Very often, when repairing furniture or assembling it, you need to accurately drill holes for the firmmat, dowel and other fasteners. If you drill a sheet of chipboard, it is almost impossible to do this with a simple drill, since the hole breaks and it is not always possible to make a right angle. Therefore, for such work you must have a tool called a jig.
Classification of conductors
The main function of jigs is to ensure straightness in drilling wooden surfaces throughout the entire depth of the hole. Such devices are used quite often in metal processing and, as a rule, are supplied directly with the machine. Due to the need to create such holes in furniture production in large quantities, such devices are in great demand among craftsmen.
There are the following types of conductors:
If the jig has sufficient rigidity, then it can be used not only on flat planes, but also for curved pipes, etc. In this case, it is secured with a clamp. But under no circumstances should it be used for fastening to wooden surfaces, as you can damage the furniture. You can buy it in a store, or you can also make it yourself.
The jig is in fact a template for making holes, with the help of which such work can be done with maximum accuracy. Due to the simplicity of the structure, they are often used not only in the areas of furniture production. In particular, they are actively used in the field of mechanical engineering for drilling holes in various workpieces, etc. We should not forget about the furniture industry, where such a device is used for various needs when assembling furniture fittings.
Features of self-production
When designing a conductor for confirmation, it is necessary to correctly calculate what functions it will have to perform in the future. It should be done for the most commonly used fasteners in the house. If such a device is required by furniture makers for permanent job, then it is better to buy a factory sample, which is characterized by great accuracy. In addition, manufacturers often include additional fasteners, stops and templates in the kit.
The price of such a device for professional use ranges from 400 to 1100 rubles. It depends on the immediate capabilities of a particular unit, the number of holes made, their length, etc. Many people are interested in how to make a furniture jig with their own hands. Drawings with dimensions are a must for novice craftsmen, as they allow you to make a high-quality design on the first try. Similar diagrams can be found on the Internet.
Basically, the conductor has the following elements:
- The basis of the product. It is directly applied to the plane of the furniture, on which the holes will be drilled.
- Guide bushings. A drill goes through them.
- Surface clamping parts. As a rule, they are located at the end of the conductor.
To start designing your own conductor, you need to choose the right corner. It is better to make a non-equivalent corner, since it will have much more possibilities, and choose the maximum thickness of the shelf.
Next you need to take care of in the right direction bushings. It can be made from stainless pipe. The length of the sleeve should be at least twice as long as the hole in which it will be located on the angle. The bushing should fit tightly in the hole. The simplest and most common option is planting according to the shaft principle. A corresponding hole is drilled in the corner for the already known diameter of the bushing, and then the fit is made. It is recommended to use a low interference fit.
There are cases when the jig needs to be made for drilling deep holes. Then the bushing is made with a collar. The number of possible holes, their length and the distance between them is selected to suit the specific needs of each master.
Several options can be used to attach the device:
Design for confirmations and dowels
Furniture jig for drilling holes for dowels and confirmat - very necessary equipment for furniture makers. Especially if chipboard material is used.
For these purposes, two types of conductors are used:
- Dowel jig with clamp fastening with many functions. The basis of this design is a corner made of thick aluminum. Since the device is quite long, there is an additional fastener in the middle. When turning the angle ninety degrees, the increased thickness of the device helps a lot. The bushings on the structure are located at the distance most often used for confirmations and dowels in furniture production.
- A two-slider jig, which is used to make a hole in two parts fastened together. The design consists of two strips that are connected by fasteners. It has several holes, so you can install devices at different widths.
Scope of use
Furniture jigs are devices that no furniture maker can do without in the process of work. Such devices allow you to avoid the main problem in furniture production, namely the drill entering at the wrong angle. If you make such a mistake, it is very difficult or even impossible to correct it later. Such a device not only makes it possible to correctly direct the drill during operation, but also allows the tool to constantly maintain the desired trajectory (flat, perpendicular or at an angle).
Such devices are used both in the design and production of furniture, and during assembly, when there is a need to make holes for fastening elements together. Often, for such actions, conductors are used for firmmats or dowels, without which it is impossible to make straight holes. Also, you can’t do without this device if you need to make holes at an angle or at the end thin slab(it is especially important to use the device when working with chipboards).
When drilling holes using this design, the process itself is quick and simple. The fastener allows you to do work at any distance from the edge of the slab, as well as regardless of its width.
In the furniture industry, dowels are often used as fasteners. But at the same time, this option has already existed for a long time, and their use requires the presence of a drilling jig when working. The only condition and at the same time a problem is the fact that the parts being connected to each other must have a right angle during operation. Therefore, such elements must be located exactly perpendicular to each other. When making holes for dowels and adding parts, it will be very difficult to do without a jig.
Furniture production is not the only area of application for such devices. They can often be used to make holes in pipes and other round-shaped parts. Special devices allow you to make high-quality holes even in the smallest tubes.
The principle of their operation and dimensions may be different. Some narrow-profile models are better to buy than to produce yourself. But, on the other hand, the price similar devices not small, so this is a disadvantage when compared with homemade models.
How to make it yourself
The most simple designs they are cheap, and professional furniture makers are not puzzled homemade production, but prefer to buy factory models. But there are also craftsmen who want to make such a device with their own hands.
For self-creation The conductor needs to use drawings, of which there are a lot on the Internet. With your own hands you can make simple designs for confirmations and more complex ones for dowels.
For production you need to prepare the following tools:
- drill;
- classic set of tools for a locksmith;
- welding;
- Bulgarian.
The simplest conductor can be made from improvised means, which are generally found in any household, in a workshop in the country or in a garage. To create it, the simplest materials are suitable, such as reinforcement, metal sheets And wooden blocks etc. They can significantly save money in the production of such a device.
The manufacture of such a device should be carried out in several stages:
To ensure that there is little dust during operation, it is necessary to install half of the plastic bottle. It will also collect dust.
Today in construction, devices are used that facilitate the processing of materials. For example, a jig for drilling holes is one of those devices that allows you to carry out work without the use of any marking tools.
What is the product?
The presented device allows you to do the job as accurately as possible. It is a special box that provides the necessary hole parameters. That is, you can easily adjust the angle of entry of the drill into the material being processed. Moreover, if there are several parts, then drilled holes will match.
It must be said that such devices can be purchased at any hardware store. Their cost ranges from 1000-2500 rubles. However, you can make a jig for drilling holes yourself. This is especially necessary if the work requires special parameters.
Advantages of the device
The drilling jig has the following advantages:
Reasonable cost and the possibility of making it yourself.
There is no need to use a ruler, pencil or other means to mark the surface to be treated.
Reducing the labor intensity of the procedure.
Very simple use of the product, intuitive even for an amateur.
As you can see, a hole drilling jig is a very useful device for household or for a small business.
Areas of application of the product
In principle, such a device can be used almost anywhere. For example, it can most often be found in the process of making furniture. This kind of work requires precise parameters. The use of measuring instruments takes large number time. This entails additional expenses, which can be disastrous for a small business.
The conductor is also a very important device in mechanical engineering. Here the equipment of the device plays a huge role. It must be as accurate as possible. As you can see, the presented device is quite common and useful. It makes your work much easier.
Device design
The jig for drilling holes, a drawing of which you can see in the article, may have different designs. It all depends on the purpose for which the device will be used. For example, if you purchased a device in the form of a small strip or corner with holes drilled in one line, then with its help you can make holes in one row at right angles.
If you do not need such a design, but need more difficult option with holes that are not on the same axis, then you will have to make the device yourself. You can find out how to do this below. However, first you need to understand the varieties of products presented. As you can see, the jig for perpendicular drilling of holes has a not too complex structure that even an inexperienced craftsman can figure out.
Classification of devices
So, we can distinguish the following types of devices:
Stationary. They differ in that they do not have rotating elements capable of moving the workpiece. That is, those products that are drilled are of the same type.
Invoices. Their feature is considered to be simplicity of design and low cost. To operate such a device you simply need to put it on the part that will be processed. It must be secured with a washer and nut.
Tiltable. They are capable of drilling several holes in one part. Moreover, they can have different angles relative to each other.
Rotary. In this case, the location of the conductor bushing is determined by the dividing disk.
Rocky. Such products are most often installed on professional drilling machines. They are especially in demand in the mechanical engineering industry.
How to choose the right device?
In order for the hole drilling jig, the photo of which is presented in this article, to successfully cope with the tasks assigned to it, you need to purchase correct device. When choosing and purchasing, try to follow these recommendations:
1. Type and purpose of the device. This parameter is the most important. If you choose the wrong device or its accessories, it will be useless to you and your money will be wasted.
2. Cost of the device. This parameter is also important. You should not give preference to the cheapest products that may come apart the first time you use them. Buy durable metal devices.
3. Manufacturer's warranty. Do not purchase an item from basement. There you are not insured against counterfeits or defective goods. It is better to contact an official certified point of sale, where you can exchange the product under warranty if it does not suit you or turns out to be non-functional.
4. Additional features. Today, a jig for drilling pocket holes can be equipped with special devices that help eliminate dust during operation, or with other devices.
5. Manufacturer. Here everything depends on your taste and the reputation of the manufacturer. Now the most popular is the Wolfcraft hole drilling jig.
Features of self-production
This is not at all difficult to do. First you need to select required material. A channel or corner is best suited for this purpose. Naturally, before processing the workpiece, it is necessary to make a template according to which the holes will be drilled. The diagram can be drawn on a regular sheet of paper.
Next, you need to make markings on the workpiece itself. After this, it must be clamped in a vice or using clamps, and only then drilling can begin. Please note that doing this strictly perpendicularly is quite difficult. The fact is that you can manually make a hole with a certain deviation. Moreover, the thicker the workpiece you choose, the more difficult it will be to work with.
Next you just need to drill holes at the marked locations. When doing this, take into account the diameter of the drill. It must exactly match the size of future holes on the material being processed. It is best to use for this purpose drilling machine. It is this that will allow you to achieve the desired angle of 90 degrees. If there is no drilling machine, then the drill must be fixed so that it does not deviate. To do this, you can use all kinds of stands.
Features of the device
The KWB hole drilling jig, like any other device of the presented type, must be used correctly. Only in this case will you be able to achieve a positive result. So, try to comply with these conditions:
During operation, all parts, as well as the device itself, must be as clean as possible from dust or other contaminants.
Try to choose exactly the drill that will suit your diameter.
Please note that when installing the jig, it must lie flat against the plane of the table. Naturally, at this stage you should also set the drilling depth.
When selecting the rotation speed of the drill, it is necessary to check that the drill is installed correctly for runout.
The workpiece must be very firmly fixed to the jig.
The drill must be brought to the product through the guide sleeve and drilling must begin.
Please note that you should not press too hard on the tool while working. Otherwise, the drill may simply break or lose its sharpness.
After completing the work, you must carefully remove the tool from the part and unscrew the jig.
During all manipulations, try to comply with safety rules as much as possible. For example, wear protective clothing, gloves and goggles. If you feel that the tool is starting to malfunction, stop working immediately. Otherwise, you risk injury.
That's all the features of using the conductor. Good luck!
Precision drilling, used to connect wooden, metal and other elements with each other, is the key to the fact that the product will be of high quality, without backlash, durable and will be used effectively for a long time. In case chipboard processing, OSB, MDF and other materials, it is recommended to use a jig to drill holes to achieve successful results.
Need for an assistive device
A do-it-yourself drilling jig helps with both living conditions, and during industrial processing. This product is a thick metal strip. It has several holes, inside of which there are special bushings - sleeves.
Template makers can be manufactured in different options, but everyone has the same task - marking for drilling
A step-by-step algorithm that involves using a jig to drill holes in workpieces consists of the following steps:
- determine the drilling location;
- apply a conductor to it;
- fix the device in a convenient way;
- We put sleeves in the holes;
- drill in the indicated places.
Classification of markers
A jig for drilling holes with your own hands is used in different areas production activities. Based on similar characteristics, similar auxiliary devices are usually divided into several groups:
Jig for drilling holes
An overhead jig with a turret head is suitable for drilling standard holes for dowels of any size
The group is called this way because of the way it is operated. The product is usually installed on top of the intended workpiece and fixed using screw terminals. Less often, at home, it is based on an emphasis on any plane. This way you can mark holes for furniture screws.
Rotary jig for drilling holes
This jig is used for drilling at an angle. Comfortable processing is achieved due to guide bushings.
Tilting jig for drilling holes
Tiltable for use on multiple surfaces
The group is involved in drilling on several surfaces located at an angle to each other.
Sliding jig for drilling holes
They are in demand in areas where it is not possible to fix the marker. The guide bushings are mounted on folding bars.
Not only jigs are widely used for drilling holes for confirmation, but templates are also used in mechanical engineering, when it is necessary to make many of the same type of drills in workpieces.
This device has many advantages:
- achieves maximum accuracy in finished products;
- ease of operation;
- the ability to repeat the center distance on any surface in convenient time;
- affordable cost of the finished product;
- You can make a homemade jig for any workpieces and different center distances.

Scope of application
During the furniture assembly process, some drawings indicate where to drill holes where the pins will be located inside. In such a situation, you cannot do without an accurate tool. It will not be possible to align the mates on the parts being connected as clearly as possible with simple markings, so a furniture jig will be useful for drilling holes.
Even a simple device in the form of a strip with a stop greatly facilitates and speeds up the process of making holes of the same type
In addition, the templating engine facilitates quick detection of the required points after the marker is located. In addition to holes for dowels, cavities for installation are also needed door hinges. They can also be made using a rigid stencil.
Marking and drilling multiple holes at an angle or perpendicularly, at the end or on the main surface in a pipe without help is always problematic. This is due to the special geometry of the workpiece. You can also save time and get the desired result thanks to the conductor. The set of auxiliary devices can be supplemented with an installation that ensures perpendicularity of the drill entry.
The difference between store-bought and homemade
Importance of this equipment, which performs an auxiliary function, is difficult to overestimate. Some people prefer to do it with my own hands so that the product has the necessary functionality and is suitable for a specific job. Other experts strive to choose the most comfortable product from the products offered in online stores.
When purchasing, you need to pay attention to the manufacturer. The final price tag depends on the capabilities of the template. At home, it is enough to use household units, but for daily operations it is worth acquiring a professional product.
Making it yourself doesn't take much time. Also suitable materials always at hand.
Homemade device
It must be taken into account that this device includes a certain number of parts:
- body corner element, which must be applied one by one to the workpieces intended for connection with dowels or self-tapping screws;
- guide sleeves-sleeves through which the drill will pass during the drilling process;
- clamps that provide a strong connection between the tool and the workpiece through a screw or cam connection.
A homemade template should include drawings and markings that are most often found at home on furniture and other areas. You will need to stock up on special stops to help with the work. The average cost of finished samples will be about 500-1000 rubles. The difference between them is the dimensions, functionality and the number of guide bushings.
Assembly drawing of a homemade marker
How to make a jig for drilling holes with your own hands
Design begins with choosing a corner that will serve as a base blank. It is preferable to choose a base with different sides, as well as the greatest possible metal thickness. According to GOST 8510, the most acceptable products will be those with side parameters of 63x40 mm and 8 mm thick. With such overall dimensions, it will be possible to use bushings 6 mm long, and there will be internal space for a drill of no more than 4 mm in diameter.
In most cases, these values are enough to make your own template with your own hands. Additionally, you will need bushings, which at home are usually cut from stainless steel, corresponding to GOST 9941 or GOST 9940 for seamless and all-welded pipes, respectively.
The choice should begin by selecting a tube according to its internal cross-section. Usually the 6x1 mm format is used, which makes it easy to use a drill with a diameter of 3.6-3.7 mm. It is important to follow the rule that the minimum sleeve length can be twice the outer diameter of the tube.
The liner is seated with a slight interference fit or in a transitional format. It makes sense to do it in a shaft system, because the basis will be a stable outer diameter of the tube. It is for this that the voids in the corner are drilled. It is worth using the h9/P10 fit.
In some cases, a scriber is required to make sufficiently deep holes. This technique involves the presence of a stepped sleeve with collars. Strict GOST 12214 determines the parameters for machine jigs.
How many sockets to drill and how to position them is determined by the owner of the tool independently according to his needs. Traditionally, one of the following mounting options is chosen:
- using a spring-loaded stop that presses the jig to the part thanks to the elastic material;
- You can firmly fix the conductor using self-tapping screws, but when working with chipboard and similar materials, you should refrain from this method;
- external clamps, under which there are rubberized gaskets for safety reasons.

A drilling jig is an indispensable attribute in large-scale production, no matter what kind. Where there is a lot of drilling, it is really necessary, especially when production is serial or mass.
With the help of a conductor, production is greatly accelerated and the worker's work is made easier.
A drilling jig, as a rule, is a bar (plate) with holes and bushings (sleeves). Using a jig it is much easier, for example, to drill pipes.
As for furniture production, they are also used here, although relatively recently.
With the help of such equipment, the manufacturer is relieved of the following problems:
- Marking.
- Punching (point depressions in the material for a drill).
- Drilling while maintaining perpendicularity.
The latter is especially difficult to achieve, since it requires serious skills acquired only over the years.
Some operations, for example, drilling for dowels (short wooden rods designed for hidden joining of parts), require very precise markings, and no less accurate drilling at an angle of 90°.
With such a device as a conductor, these tasks are solved easily and simply.
Types: choose the one you need
Invoices. They do not require fixation before being used for their intended purpose. Structurally simple, mobile, but they need to be held with a hand free from the drill, since often the equipment is not secured in a special device, which is not very convenient. Considering the simplicity of the design, making it yourself is quite simple. Used when drilling chipboard and MDF.
Jigs for drilling holes at an angle. The design is easy to imagine, since the name speaks for itself. Such equipment can also be an overhead one. In production quality furniture There is also drilling at an angle, which is not the simplest operation in the production process - this requires skill. Although in this case the required angle is sometimes violated, the assembly as a result will not be of such high quality and will suffer appearance furniture, especially if it is not made of chipboard, but of wood - here you won’t be able to fill in an unsightly drill. The equipment desired design completely eliminates unnecessary problems.
Rotary conductors. They have folding brackets, and this allows drilling on two adjacent planes.
Sliding gearboxes. With their help, you can drill several holes without reinstallation. To work with such equipment, the necessary skills are still required.
Device for drilling holes for dowels and confirmats
Despite the fact that today a lot of new accessories have appeared in the furniture industry, the good old dowel is still used. This is explained by the fact that the connections are not visible through this piece of fittings, and this is especially valuable in the production of furniture made from natural wood.
As already mentioned, drilling for dowels creates many problems for furniture makers, especially those who are not sufficiently qualified.
In order for the furniture planes to fit perfectly together, precise markings are necessary, and this equipment allows you to speed up the work and bring the quality to the required level.
Working with confirmats - special furniture screws - although less troublesome, also requires certain skills. And considering how many holes need to be marked and drilled before screwing the confirmation into one piece of furniture, such a device will significantly speed up the work, and its quality too.
The simplest devices
- The conductor is two-slider. It allows you to drill holes in two adjacent (mating) parts. The device is constructed of two rulers, which serve as guides and are connected to a mounting strip. The holes made in it make it possible to install the strip on parts of different widths. Housings moved along rulers (replaceable) have a set of guide bushings, where the distances between them are different. The conductor is fixed by means of a connecting strip, and on the opposite side there is a travel limiter, pressed by a thumbscrew.
- The conductor is multi-position. Fastened with clamps. The design allows for vertical drilling. It is made of thick-walled aluminum angle. Since the device is quite long, it is equipped with an intermediate fastening in the center of the structure. The thick wall of the angle was used very successfully, which cannot be overestimated at the moment of placing the device on the surface of the part and when reinstalling the jig to 90°. The selection of the distance between the bushings is carried out according to the most common values provided for installing dowels or confirmations.
Procedure for working with a conductor:
- The device is fixed on the workpiece.
- The sleeve is inserted into the hole.
- Drill through the sleeve.
DIY furniture jig: drawings with dimensions to help
The principle of this equipment:
- Angular housing. It is superimposed on the planes of the parts, which will then be connected to each other.
- Guide bushings. The drill will go through them.
- Clamping devices. They fix the conductor and are made from the end part.
Designing your own jig should be based on the fact that with the help of this equipment it is possible to do most of the work performed related to various types of fasteners.
Important! If you need a universal assistant - this applies to professional furniture makers, then it would be better to purchase industrial equipment that is made more accurately and with high quality. It is this kind of device that will be preferable and will quickly pay for itself, especially if you also take into account the fact that this device often comes with many different templates, stops and other little things that are also necessary in the work. They are much cheaper than buying at retail.
And yet this device, if necessary, can be made with your own hands.
Such equipment may not be needed very often in a given production, let alone home handyman- especially. So for many users it will be much more profitable to do it themselves.
If the design of such remains relevant, then you need to prepare materials for the manufacture of a homemade conductor for drilling for confirmation:
- Corner. Your choice should be made on the unequal type of this rental - its possibilities are wider. The corner shelf should be chosen with the greatest thickness, which can reach up to 8 mm. This is quite justified, since then it is possible to insert guide bushings with an outer diameter of up to 6 mm. Based on this, you can use drills from 3.5 to 4 mm. Even if that diameter is not enough, then the material is drilled out with a large drill, without using any other devices.
- Guide bushings. Here, stainless steel pipes will be preferable, which are selected primarily by internal diameter. Example: a 6x1.5 pipe is suitable for a drill no larger than 2.7 in diameter. Explanation: its internal hole will be 3 mm, and a small gap along the entire internal diameter is taken into account due to thermal expansion of the material. The length of the sleeve is the depth of the hole in the corner, multiplied by two or more. The fit of the bushings is either transitional, or with an interference fit, or according to the shaft system. The latter is the most appropriate.
Instead of pipes, of course, you can use ready-made bushings used in wire drawing machines - these are available, for example, in mechanical engineering. Such parts (even used ones) come in handy: they are made of alloy steel and have an almost unlimited service life.
Choosing a mounting method
Options:
- Fixation using self-tapping screws. They are screwed into the part, which prevents the device from moving due to friction. This is convenient because these marks will be needed for subsequent drilling of other holes.
- Spring stop. It will securely fix the jig to the part. For such a stop, a flat spring with an appropriate clamping force is suitable.
- External clamps. Rubber pads must be placed under them. Corrugated rubber is ideal as a material. This, of course, slightly increases the weight of the equipment, and the elasticity of the pads can negatively affect the perpendicularity of the bushings. To prevent this from happening, the drill is inserted into the sleeve to mark the hole, and only then the clamps are clamped.
For drilling pipes and cylindrical parts
IN modern furniture Not only chipboard, fibreboard, MDF and wood are used. As additional elements may be applied steel pipes of various diameters. Covered with chrome or stainless steel, they perfectly complement the overall furniture ensemble.
It is very difficult to drill into a spherical surface - the drill tends to slide to the side. And it’s not so easy to mark when there are a lot of holes and they are located in several rows.
In order to ensure that the pipe does not turn out to be the notorious colander, but the correct part with precisely made holes, you will need a jig - this perfect solution in the current situation.
There are steel conductors made in the form of an adjustable clamp. This design feature allows pipes to be clamped into them different diameters and drill holes in them with high precision.
Not being able to make such a device, you can use waste materials, making an even simpler device using a block and a strip of plywood. Thus, a block cut diagonally lengthwise into circular saw, can be nailed or screwed with screws at an angle of 90° to the plywood. The resulting device is placed on top of the pipe, and a strip of plywood, resting against a table or workbench, prevents the specified angle from being violated. Holes of the required diameter pre-drilled in the block are placed taking into account the required distances between future holes, which will allow you to quickly and accurately drill the pipe exactly according to the drawings.
DIY furniture conductors and templates
How conductors are made is now clear, as is their necessity for furniture production.
Not only conductors, but also templates are needed in furniture production. The simplest template will sometimes save a lot of time and allow drilling to be no less accurate than a jig.
For example, the simplest metal prefabricated invoice template, consisting of two sheet blanks measuring 130×70 mm and a steel square with a cross-section of 20 mm. They are connected to each other with screws at the top of the structure - this is how they are attached to the square. The square is drilled for the bushings, where the latter are pressed. Such a device for drilling holes in the end of a part made of chipboard will make it possible to drill without thinking about marking and perpendicular drilling. And the price of this equipment is below any idea of savings.
Instead of metal, you can and should use those materials that are inexpensive and easy to process.
Materials:
- Plywood.
- Textolite or fiberglass - preferably thick.
- Hardwood.
- Hardboard or its equivalent.
It must be borne in mind that these materials are short-lived, and so that the devices do not have to be made every day, it is quite reasonable to press metal tubes into them.
In conclusion, it is worth summing up what has been said. Making a conductor or template yourself or buying it in a store is a matter for everyone individually. If a home craftsman needs to make some furniture in a single copy and there is material for a conductor, as well as the possibility of making it, you can use this. It is possible that such equipment will never be useful to the master again.
But if even a small furniture workshop is engaged in the production of serial furniture, and enough people work in it, it is probably easier to purchase something ready-made, especially since these irreplaceable helpers They will need several masters.
In the latter case, it makes sense to purchase more expensive, accurate and wear-resistant jigs instead of making homemade ones, which are less accurate and durable.
Good luck in your work!
A jig for drilling holes is a device used in mechanical engineering to simplify the process of processing a part. In essence, it is a template that serves to guide or position the workpiece. Can be used on various equipment, such as a diamond drilling machine.
In mechanical engineering, jigs are fairly precise devices (up to 0.05 mm (depending on the requirements for the part being manufactured)). They come in two main types: overhead (in the form of slabs) and box-shaped, which are three-dimensional structures. There are also jigs for mixed type drilling. These devices are used to reduce labor intensity: from technological process When processing the part, the marking operation is eliminated, in addition, it becomes possible to drill several holes at the same time.
The drilling jig is used only in serial and mass production. This is explained by the fact that for a small batch of parts it is not practical to manufacture a separate device, which, moreover, will have to be installed and configured separately.
A drilling jig is usually used to process several holes lying in the same plane. It is best if the parts are unified by standard size, this will allow the device to be used for a wide range of products.
The drilling jig is also used in light industry and construction. Such devices are only of the overhead type and are made of lighter materials, such as wood or plexiglass. These products are not designed for great accuracy; the positioning error is only ±0.5 mm. But this is more than enough to make holes for fittings in furniture or drill a series of holes in the wall of the house. The equipment used is a regular drill or a tabletop drill press.
You can make your own conductor for household needs. It will be needed during repairs, when you need to make a lot of the same type of holes and there is no desire to waste time on preliminary marking. To make it, you can use any available materials: on a sheet of metal or wooden board mark and drill all the necessary holes that will serve as guides. If necessary, an additional plumb line is made so that shavings or concrete chips do not fall on the floor. You can make a dust-free jig when the template is covered with a specially fitted half of a plastic bottle.
The main advantages of these devices are high positioning accuracy of holes without preliminary marking, high labor productivity and reduced perpendicularity deviation (due to guide bushings). However, using a jig for drilling is not always economically justified, especially with small batches of parts in production.
