Drilling jig - an indispensable attribute on large-scale production, no matter which one. 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, the work of the worker is facilitated.
A drilling jig, as a rule, is a bar (plate) with holes and bushings (sleeves). By means of a conductor, it is much easier, for example, to drill pipes.
As for the production of furniture, they are also used here, although relatively recently.
With this equipment, the manufacturer is relieved of the following problems:
- Markup.
- Punching (point recesses in the material for the drill).
- Drilling with observance of perpendicularity.
The latter is especially difficult to do, since it requires serious skills acquired only over the years.
Some operations, such as dowel drilling (short wooden rods designed for concealed joining of parts), require very precise marking, and no less precise 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
Overhead. They do not need fixing before their intended use. Structurally simple, mobile, but they need to be kept free from the drill by hand, since often the equipment is not fixed in a special device, which is not very convenient. Given the simplicity of the design, making it yourself is quite simple. Applicable for chipboard drilling and MDF.
Conductors for drilling holes at an angle. The design is easy to imagine as the name speaks for itself. Such equipment can also be consignment note. In production quality furniture there is also drilling at an angle, which is not the easiest operation in manufacturing process- it takes skill. Although in this case it is sometimes violated desired angle, as a result, the assembly will no longer be of such high quality and suffer appearance furniture, especially if it is not made of chipboard, but of wood - here you can’t putty on ugly drilling. The equipment of the 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, without reinstallation, you can drill several holes. To work with such equipment, however, the necessary skills are required.
Device for drilling holes for dowels and confirmations
Despite the fact that today furniture industry a lot of new fittings appeared, the good old dowel is still used. This is due to the fact that the joints are not visible through this piece of fittings, and this is especially valuable in the production of natural wood furniture.
As already mentioned, dowel drilling creates a lot of problems for furniture makers, especially those who are not qualified enough.
In order for the furniture planes to be perfectly joined, it is necessary precise marking, and this equipment allows you to speed up the work and bring the quality to the desired level.
Working with confirmations - special furniture screws - although less troublesome, but also requires certain skills. And given how many holes you need to mark and drill before screwing the confirmation in one piece of furniture, such a device will greatly 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 fixture is constructed from two rulers that serve as guides and are connected to mounting plate. The holes made in it make it possible to set the bar on the details different widths. Housings moved along the 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, with opposite side there is also a stroke limiter, pressed by a lamb screw.
- The conductor is multiposition. Attaches with clamps. The design allows for vertical drilling. It is made from thick-walled aluminium. Since the device has a considerable length, it is equipped with intermediate fastening in the center of the structure. The thick wall of the angle was very successfully used, which cannot be overestimated at the moment the device is applied to the surface of the part and when the conductor is reinstalled by 90 °. The selection of the distance between the bushings is carried out according to the most common values \u200b\u200bfor the installation of dowels or confirmations.
How to work with a conductor:
- The device is fixed on the workpiece.
- The sleeve is inserted into the hole.
- Drill through the sleeve.
Do-it-yourself furniture conductor: drawings with dimensions to help
Principle of this equipment:
- Corner case. It is superimposed on the plane of the parts, which will then be connected to each other.
- Guide bushings. A drill will enter 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 this equipment you can do most of the work performed related to fasteners of various types.
Important! Kohl needed universal helper- this applies to professional furniture makers, it would be better to purchase industrial equipment, which is made more accurately and efficiently. It is such a 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 a lot of 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, perhaps, is needed not so often in a particular production, and even home master- especially. So for many users, doing it yourself will be much more profitable.
If the design of such remains relevant, then it is necessary to prepare materials for the manufacture homemade conductor for drilling under confirmation:
- Corner. You should stop your choice on the unequal type of this rental - its possibilities are wider. The corner shelf must be chosen with the greatest thickness, which can reach up to 8 mm. This is quite justified, since then you can insert guide bushings, outside diameter which reaches 6 mm. Based on this, drills from 3.5 to 4 mm can be used. Even if that diameter is not enough, then the material is drilled with a large drill, without using any other devices.
- Guide bushings. Here it will be preferable to use stainless steel pipes, which are selected, first of all, according to the inner diameter. Example: a 6×1.5 pipe is suitable for a drill no larger than 2.7 in diameter. Explanation: its inner hole will be 3 mm, and a small gap along the entire inner diameter is taken into account due to the thermal expansion of the material. The sleeve length 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 - such are available, for example, in mechanical engineering. Such parts (even used ones) will come in handy: they are made of alloyed steels and have an almost unlimited service life.
Choice of mounting method
Options:
- Fixation with 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.
- The emphasis is spring. It will securely fix the conductor on the part. For such an emphasis, a flat spring with an appropriate clamping force is suitable.
- Clamps external. They need to be placed underneath rubber gaskets. Corrugated rubber is ideal as a material. This, of course, slightly increases the weight of the tool, and the elasticity of the pads can negatively affect the squareness of the bushings. To prevent this from happening, the drill is inserted into the sleeve in order to mark the hole, and only then the clamps are clamped.
For drilling pipes and cylindrical parts
AT modern furniture not only chipboard, fiberboard, MDF and wood are used. As additional elements may apply steel pipes different diameter. Covered with chrome or stainless steel, they perfectly complement the overall furniture ensemble.
It is very difficult to drill a spherical surface - the drill strives to slip to the side. Yes, and marking is not so easy when there are a lot of holes and they are arranged in several rows.
In order for the notorious colander to turn out of the pipe, but the correct part with precisely made holes, you need a jig - this perfect solution in the given situation.
There are steel conductors made in the form of an adjustable clamp. This design feature allows you to clamp pipes in them different diameter and drill holes in them with high precision.
Without being able to make such a device, you can use waste materials, making an even simpler device using a bar and a strip of plywood. So, a bar cut diagonally lengthwise into circular saw, can be nailed or screwed with screws at an angle of 90 ° to plywood. The resulting device is superimposed on top of the pipe, and a strip of plywood, resting against a table or workbench, does not allow the specified angle to be violated. Pre-drilled holes in the bar desired diameter 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.
Do-it-yourself furniture conductors and templates
How conductors are made is now clear, as well as their need for furniture production.
Not only conductors, but also templates are necessary in furniture production. The simplest template will sometimes save a lot of time and enable no less accurate drilling 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 interconnected by screws in the upper part of the structure - this is how they are attached to the square. The square is drilled under 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 at all. And the price of this equipment is below any idea of \u200b\u200bsavings.
Instead of metal, you can and should use those materials that are inexpensive and easy to process.
Materials:
- Plywood.
- Textolite or fiberglass - preferably thick.
- Hard wood.
- 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 summarizing what has been said. Making a jig or a template yourself or buying it in a store is up to each individual. If a home craftsman needs to make some kind of furniture in a single copy and there is material for the conductor, as well as the possibility of manufacturing 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 mass-produced furniture, and enough people work in it, it is probably easier to purchase something ready-made, especially since these irreplaceable assistants they will need masters in several copies.
In the latter case, it makes sense to purchase more expensive, accurate and wear-resistant conductors instead of making handicraft ones that are less accurate and durable.
Good luck in your work!
In the manufacture of cabinet furniture, it becomes necessary to be able to accurately and quickly drill into the end of parts. As a rule, this need is due to the use of euro screws (confirmants), in which holes with diameters of 4.5-5.0 mm are drilled into the end of the parts (depending on the density of the plate) to a depth of 35-55 mm (depending on the length of the euro screws).
Of course, for such purposes there are special drilling and welding machines, but they are not easily accessible to private furniture makers or small organizations due to their high price, plus to this, the machines are not convenient due solely to stationary use. To simplify the work of a furniture maker, conductors were invented - small devices for precise drilling with a conventional hand-held electric drill. Today there are several manufacturers on the market, paying no low price, you can buy a ready-made conductor. This article will discuss how a good home-made jig can be made from improvised and easily accessible material in a couple of hours.We use ball bearings as guide bushings. The bearings are made of durable steel and will last a long time. In order for the drill to be well oriented in the jig, two bearings are used for each working distance (bearings are arranged coaxially one under the other).
To make a conductor (for three working fixed distances), we need:
- A piece MDF boards 16mm thick.
- A piece of MDF board 10mm thick.
- Six pieces (a pair for each working distance) of any ball bearings with an inner diameter of 5.0 mm, an outer diameter of not more than 16 mm. The height of the bearing should be as small as possible and no more than 8mm.
- A dozen self-tapping screws 4x25 mm.
- Glue PVA, "Superglue".
- Futorka furniture with internal thread M6 (see photo).
- Screw M6x50. Nut M6. Washer Grover 6mm.
Manufacture of the body of the conductor.
First, you need to make the case itself. There is no need to explain anything in particular about the case, everything is elementary. The cross section of the body is the letter "P" with one end (closed) wall. This wall will be used as a stop, will set the zero point, the starting point for drilling. When drilling, the stop is pressed against the end of the part. Main dimensions:
- The external size of the conductor is arbitrary.
- The upper part, in which the bearings will be planted, is made of 16mm MDF, the rest of the parts are 10mm MDF.
- The distance between the two sidewalls (where the workpiece will be placed) is16.5mm whatcorresponds to the actual thickness of the plate plus a small gap for ease of installation and removal of the conductor.
- The distances between the centers of the bearings and the stop: 50, 70, 100 mm, are the most common in furniture practice.
To assemble the housing, it is necessary to accurately cut out all four parts (top, two side and one end), measurements are recommended to be performed with a caliper. Further, holes for self-tapping screws are marked and drilled, which will fasten all the parts together. The body is assembled with PVA glue.
The distance between the side walls of the conductor is 16.5 mm (for laminated chipboard with a nominal thickness of 16 mm).
Fitting bearings.
After the glue dries, we proceed to marking and punching the holes for the bearings. We try to be very accurate in this operation! To drill holes for the bearings, we need either a drill fixed in the rack. Run precise drilling by hand is very difficult, but, with a certain skill, it is possible. We mark the centers of the bearings with a pencil, kernim. By punching, we drill three through holes with a diameter of 2 mm. We clamp a feather drill (punch) into the drill chuck, the diameter of the punch should be equal to the outer diameter of the bearings. We drill two blind (non-through) holes for each bearing on each side of the previously drilled through hole. The drilling depth of the punch (the penetration depth of the central pin is not taken into account) should be approximately 1 mm greater than the height of the bearing. As a result, we should get six mounting holes(three on each side) for bearings. You can try to insert bearings in seats, the bearings should enter freely, but without noticeable play. After fitting, you need to lubricate the outside of each bearing with glue and put it all the way in its place. If "Super Glue" is used (it absorbs and dries quickly), then this operation is performed using a rubber mallet.
Top conductor. Distances between bearing centers and stop.
Making an adjustable stop.
To be able to drill at any arbitrary distance from the stop (not only 50, 70, 100 mm), it is necessary to supplement the jig with a simple adjustable stop - a long screw. Drilling in the center of the end stop through hole with a diameter of 0.5 mm less than the outer diameter of the furniture fitting (see photo). We twist the futorka. We screw a long screw into the futorka, not forgetting to first screw the nut onto the screw and put on the Grover washer. Now, by changing the depth of the screw, you can set any drilling distance from 0 to 100 mm.
Furniture booth. You will need a hex wrench to screw the futorka into the jig body.

Drill out. This maximum depth can be drilled.The length of the drill used and the depth of its fastening in the drill chuck should be selected taking into account the thickness of the conductor (that is, almost the total height of the two bearings).
If desired, the surface of the conductor can be sanded with a fine sandpaper, primed and painted (for example, spray enamel). Practice has shown that the accuracy of drilling with a jig is no worse than +/-0.5 mm and largely depends on how much the actual thickness was made (plateschipboard) differs from the calculated thickness. In any case, an error of a maximum of half a millimeter is not critical for end-to-end drilling in the manufacture of cabinet furniture.

Very often, when repairing furniture or assembling it, it is necessary to accurately drill holes for the firmament, dowels and other fasteners. If drilling chipboard sheet, then with a simple drill it is almost impossible to do this, since the hole is broken and it is not always possible to make a right angle. Therefore, for such work, it is imperative to have a tool called a jig.
Classification of conductors
The main function of conductors is to ensure straightness in drilling wooden surfaces throughout the entire depth of the hole. Such fixtures in metal processing are used quite often and, as a rule, are supplied directly with the machine. In connection with the need to create such holes in the production of furniture in large quantities, such devices are in great demand among craftsmen.
There are such types of conductors:
If the conductor has sufficient rigidity, then it can be used not only on flat planes, but also for curved pipes, etc. In this case, it is fixed with a clamp. But in no case should it be used for mounting on wooden surfaces, as you can ruin the furniture. You can buy it in the store, as well as do it yourself.
The conductor is in fact a template for making holes, with which such work can be done with maximum accuracy. Due to the simplicity of the structure 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 blanks etc. Do not forget about the furniture industry, where such a device is used for a variety of needs when assembling furniture fittings.
Features of independent production
When designing a conductor for confirmation, it is necessary to correctly calculate what functions it will have to perform in the future. You need to do it under the most commonly used fasteners in the house. If such a device is required by furniture makers for permanent job, it is better to buy a factory sample, which is highly accurate. 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 being made, their length, and so on. Many are interested in how to make a furniture jig with your own hands. Dimensional drawings are a must for novice craftsmen, as they allow you to make a design with high quality on the first try. Similar schemes can be found on the Internet.
Basically, the conductor has the following elements:
- Product base. It is directly applied to the plane of the furniture, on which holes will be drilled.
- Guide bushings. A drill goes through them.
- Parts for surface clamping. As a rule, they are located on the end of the conductor.
To start designing your own conductor, you need to choose the right corner. Better not do equal-shelf corner, since it will have much more opportunities, and choose the maximum thickness of the shelf.
Next, you need to take care of right direction bushings. It can be made from stainless pipe. The length of the sleeve must be at least twice as long as the hole in which it will be located on the corner. The bushing in the hole should sit with an interference fit. The simplest and most common option is a shaft fit. Under the already known diameter of the sleeve, a corresponding hole is drilled in the corner, and then a landing is made. It is recommended to use a low interference fit.
There are cases when the conductor needs to be made for drilling deep holes. Then the sleeve is made with a collar. The number of possible holes, their length and the distance between them is chosen according to the specific needs of each master.
Several options can be used to mount the device:
Design for confirmations and dowels
Furniture jig for drilling holes for dowel and confirmat - very necessary fixture for furniture makers. Especially if chipboard material is used.
For these purposes, two types of conductor are used:
- Clamp-on dowel jig with multiple functions. The basis of this design is a corner made of thick aluminum. Since the fixture is quite long, there is an additional mount in the middle. When turning the corner ninety degrees, the increased thickness of the fixture helps a lot. The bushings on the structure are located at the distance most often used for confirmations and dowels in the manufacture of furniture.
- A two-slider jig, which is used to make a hole in two parts fastened together. The design consists of two strips, which are connected by fasteners. It has several holes, so you can install devices at different widths.
Scope of use
Furniture conductors are devices that no furniture maker can do without in the process of work. Such devices avoid the main problem in the production of furniture, namely, the entry of the drill at the wrong angle. If you make such a mistake, then it is subsequently very difficult to correct or even impossible. Such a device not only makes it possible to correctly direct the drill during operation, but also allows the tool to constantly keep the desired trajectory (even, perpendicular or at an angle).
Such devices are used both in the design and manufacture of furniture, and in assembly, when there is a need to make holes for attaching elements to each other. Often, for such actions, conductors are used for confirmations or dowels, without which even holes cannot be made. Also, this device is indispensable if it is necessary to make holes at an angle or at the end of a thin plate (it is especially important to use the device when working with chipboard plates).
When drilling holes using this design, the process itself is quick and simple. Fasteners allow you to work at any distance from the edge of the plate, and also regardless of its width.
In the furniture industry, dowels are very often used as fasteners. But at the same time, this option has already existed for a long time, and their use requires the mandatory presence of a drilling jig during operation. The only condition and at the same time a problem is the factor that the parts to be connected to each other must have a right angle when working. 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 scope of such devices. Often they can be used to make holes in pipes and other rounded parts. Special devices make it possible quality holes even in the smallest tubes.
The principle of their work and dimensions may be different. Some narrow-profile models are better to buy than to produce on your own. But, on the other hand, the price of such devices is not small, so this is a disadvantage when compared with home-made models.
How to DIY
Most simple designs are cheap, and professional furniture makers are not puzzled homemade production, and prefer to buy factory models. But there are also such masters who want to make such a device with their own hands.
For self-creation the conductor needs to use the 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 a tool:
- drill;
- classic set of tools for a locksmith;
- welding;
- Bulgarian.
The simplest conductor can be made from improvised means, which are basically found in any household, in a workshop in a country house or garage. To create it, the simplest materials are suitable, such as reinforcement, metal sheets and wooden bars etc. They allow significant savings in the production of such a device.
The manufacture of such a device should be carried out in several stages:
In order to have little dust during operation, it is required to mount half 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 allow you to work without the use of any marking tools.
What is a 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 details, then drilled holes will match.
I must say that such devices can be purchased at any hardware store. Their cost ranges from 1000-2500 rubles. However, the jig for drilling holes can be made independently. This is especially necessary if special parameters are required for operation.
Advantages of the device
The jig for drilling holes has the following advantages:
Affordable cost and the possibility of self-manufacturing.
There is no need to use a ruler, pencil or other means to mark the surface to be treated.
Reducing the complexity of the procedure.
Very simple use of the product, intuitive even for an amateur.
As you can see, the hole jig is very useful device for household or for a small business.
Applications of the product
In principle, such a device can be used almost everywhere. For example, most often it can be found in the process of making furniture. In this work, precise parameters are required. The use of measuring instruments takes a large number of time. This entails additional expenses that can be detrimental to a small business.
The conductor is also a very important device in mechanical engineering. This is where equipment 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 the job much easier.
Device design
A jig for drilling holes, the drawing of which you can see in the article, may have different design. It all depends on the purpose for which the device will be used. For example, if you purchased an apparatus in the form of a small strip or a corner with holes drilled in one line, then with its help you can make holes in one row at a right angle.
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. How to do this, you can find out further. However, first you need to understand the varieties of products presented. As you can see, the conductor for perpendicular drilling of holes has a not too complicated structure, which even an inexperienced master can figure out.
Apparatus classification
So, we can distinguish the following types of devices:
Stationary. They differ in that they do not have rotary elements capable of moving the workpiece. That is, those products that are drilled are of the same type.
Overhead. Their feature is the simplicity of design and low cost. To work, such a device just needs to be put on the part that will be processed. At the same time, it should be fastened with a washer and a nut.
Overturned. They are able to drill multiple holes in one piece. However, they can have a different angle in relation to each other.
Swivel. In this case, the location of the drill bushing is determined by the dividing disc.
Rocky. Such products are most often installed on professional drilling machines. They are in particular demand in the engineering industry.
How to choose the right device?
In order for the jig for drilling holes, the photo of which is presented in this article, to be able to successfully cope with the tasks assigned to it, you need to purchase correct device. When choosing and buying, try to be guided by the following recommendations:
1. Type and purpose of the device. This setting is the most important. If you pick up the wrong device or its equipment, then it will be useless for you, and money will be thrown away.
2. The cost of the device. This parameter is also important. Do not give preference to the cheapest products that can disperse on the first use. Buy durable metal devices.
3. Manufacturer's warranty. Don't buy the item basement. There you are not insured against fakes 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 is not functional.
4. Additional features. To date, a jig for drilling pocket holes can be equipped with special devices that help eliminate dust during operation, or other devices.
5. Manufacturer. Here it all depends on your taste and the reputation of the manufacturer. Now the most popular jig for drilling holes is Wolfcraft.
Features of self-production
This is not at all difficult to do. To start, you need to choose necessary material. For this purpose, a channel or corner is best suited. Naturally, before processing the workpiece, it is necessary to make a template, according to which holes will be drilled. The scheme can be drawn on a regular sheet of paper.
Next, you need to make markings on the workpiece itself. After that, it must be clamped in a vice or with clamps, and only then start drilling. Keep in mind that doing this strictly perpendicular is quite difficult. The fact is that manually you can make a hole with a certain deviation. Moreover, the thicker the workpiece you choose, the more difficult it will be to work with it.
Next, you just need to drill holes in the marked places. When doing this, consider the diameter of the drill. It must exactly match the size of future holes on the material being processed. It is best to use a drilling machine for this purpose. It is he who will achieve the desired angle of 90 degrees. If a drilling machine no, 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
Drill jig holes KWB, like any other device of the type presented, must be used correctly. Only in this case can you achieve positive result. So, try to comply with the following conditions:
During operation, all parts, as well as the device itself, must be cleaned as much as possible from dust or other contaminants.
Try to choose exactly the drill that will suit you in diameter.
Please note that during the installation of the jig, it must lie flat against the plane of the table. Naturally, at this stage, you should also set the drilling depth.
When choosing the speed of the drill, it is necessary to check the correct setting of the drill for runout.
The workpiece must be very firmly fixed on the jig.
Through the guide sleeve, the drill must be brought to the product and drilling started.
Please note that during operation, do not press too hard on the tool. Otherwise, the drill may simply break or lose its sharpness.
After completing the work, it is necessary to carefully remove the tool from the part and unscrew the jig.
During the implementation of all manipulations, try to follow the safety rules as much as possible. For example, wear protective clothing, gloves and goggles. If you feel that the tool has started to act up, immediately stop working. Otherwise, you risk injury.
That's all the features of the conductor. Good luck!
