Furniture jig for drilling holes drawing. The nuances of making a high-quality furniture jig, we do it ourselves Guide for drilling at an angle
A furniture jig for drilling holes, a drawing of a kind of template that allows you to accurately install assembly elements and greatly simplifies and speeds up the process.
Using this device you can make holes for:
Dowels
futorka
pinch bolt
mounting holes for mounting plate furniture hinge
mounting holes for furniture hinge cup
center for furniture hinge flange
center of the eccentric coupler
The design consists of two parts:
Marking unit
retainer
MARKING UNIT
It is an “L” shaped plate made of thick sheet corrosion-resistant steel, in which through holes with a diameter of 8 and 3 (mm) are drilled horizontally and vertically. To ensure that the processing tool fits better into the holes, chamfers measuring 0.25x45˚ are made on its edges. The plate is hardened and ground.

RETAINER
Made from a steel circle, which allows you to install a furniture jig for drilling holes at the required distance from the edge of the chipboard being processed. The movement step is ten millimeters.
Drawing
Let's say we want to install a furniture hinge:
1.
We lay the template on the facade.
2.
3.
We drill a hole with a diameter of three millimeters to the required depth for the fastening screws of the cup.
4.
We drill a hole with a diameter of three millimeters to the required depth for further processing. The prepared hole will be the guiding center for milling a hole for the flange of a furniture hinge with a diameter of thirty-five millimeters.
5.
Place the template on the body.

2.
Install the clamp into the hole.
3.
We drill a hole with a diameter of three millimeters to the required depth for further processing. The prepared hole will be the guiding center for milling a hole for the eccentric of a furniture tie with a diameter of fifteen five millimeters.
4.
From the end of the chipboard, along one center line, we drill a through hole with a diameter of eight millimeters to the required depth
In the picture shown
IN different colors shows the center on the furniture jig for various technological operations.
The main fastening element in furniture assembly is the confirmat. It is screwed in with pre-drilled holes. It is the drilling of assembly holes in chipboard for confirmations that we will consider in this article.
To assemble the chipboard parts we will need:
- Screwdriver
- Confirmation bat
- Ruler or tape measure
- Pencil and awl
Hole depth and width
Usually a confirmat size of 6.4*50 is used. Because the thread diameter is 6.4 mm, and the diameter of the confirmation body is 4.4 mm, then for high-quality fastening of parts, the hole diameter must be in the range of 4.5-5 mm and a depth of at least 50 mm.
If the thickness of the hole is greater than the specified one, the confirmat will not hold the parts well; if it is less, its thickness can tear the chipboard.
For drilling, use a confirmat drill with a diameter of 4.5 mm, which is equipped with an additional head for drilling an enlarged hole for the neck of the confirmat, which also makes a countersink for its head.
Of course, you can also use regular drill with a diameter of 5 mm, but for high-quality fastening in the hole, you will additionally need to make space for the neck of the confirmat and its cap.
In order to perfectly fasten two parts, it is necessary to mark the places of their fastenings as accurately as possible.
On the part that will be applied to the end (the one on which there will be a through hole), you need to make two measurements - along the length (usually 5-10 cm) and from the edge - exactly 8 mm (this is if the thickness of the plate is 16 mm).
On a part that lies perpendicular, mark the drilling point at the end. Here you need to maintain the same distance in length (5-10 cm from the beginning), and in width - strictly in the center (8 mm from the edge).
Markings must be done as accurately as possible, especially along the length, because If the markings are incorrect, your parts may have extra gaps or protrusions when joined.
It is better to make a through hole in the first part, attach it to the second - and immediately use a drill to mark the drilling location at the end of the second part. And then, separately, calmly drill the hole.
We make a hole at a distance of 8 mm from the edge.
The drill should ALWAYS be held strictly perpendicular to the surface.
Before making a through hole, place a piece of unnecessary chipboard under the part. This will prevent chips from appearing on the reverse side.
When the through hole is made, the part can be drilled on the fly to drill holes for the neck and head of the confirmat.
The main rule is that when drilling at the end, the drill must be strictly perpendicular to the end of the part. If you don't hold the drill straight, the drill bit may move to the side and come out, ruining the part.
When drilling, you need to pull the drill out several times so that chips do not clog in the hole.
This option is considered the most accurate and, moreover, the fastest. But in order to make a hole in two parts at the same time, you will need to fix them before drilling. To do this, you may need special clamps, clamps and other devices.
Hole Drilling Tools
In order not to mark 8 mm from the edge both into the layer and at the end each time, you can use a special device, which, by the way, is easy to make yourself.
It represents some wooden template with a metal sleeve for the drill inside.
It looks like this, see photo:
And this is a more professional thing:
Watch a short video on precision drilling holes in chipboard for confirmations and assembly of furniture parts:
Drilling for dowels
The hole for the dowels is made with an 8 mm drill. Also, in order not to drill through the part, it is advisable to equip it with a depth limiter.
At the end we drill with the same drill to a depth of 20 mm. Do not forget that during any work the drill must be strictly perpendicular to the plane of the part.
Of course, if you picked up a drill for the first time in your life, you won’t do very well. But this activity can be learned quite quickly.
Very often, when repairing furniture or assembling it, you need to accurately drill holes for the firmmat, dowel and other fasteners. If you drill chipboard sheet, then 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 conductor.
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-equal-flanged corner, since it will have much more possibilities, and choose the maximum thickness of the shelf.
Next you need to take care of the correct direction of the sleeve. 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 to fit 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 while working. 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 cannot do without this device if you need to make holes at an angle or in the end of a 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 do 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 of such devices is not small, so this is a disadvantage when compared with home-made 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 plastic bottle. It will also collect dust.
Today, construction uses devices 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 required parameters holes. 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, the hole drilling jig is 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. Using measuring instruments takes a lot of 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 conductor for perpendicular drilling The holes have 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. However, they may have different angle in relation 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, which help eliminate dust during operation, or 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 a drilling machine for this purpose. It is this that will allow you to achieve the desired angle of 90 degrees. If drilling machine no, then the drill must be fixed so that it does not deviate. To do this, you can use all kinds of stands.
Features of using 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!
Sometimes at home you need to make holes in blanks made of wood, metal, chipboard or other material.
Rotary
The device body is equipped with bushings that adjust the rotation axes in horizontal, vertical and inclined planes. These models of jigs are designed for drilling cylindrical products.
Sliding
The name speaks for itself, the jig is not attached in any way, it is simply placed where the hole needs to be made.
Tiltable
Capable of making holes in several planes.
Stationary
They do not have rotating elements and are capable of moving the part and processing workpieces of the same type.
Universal
These conductors have a function such as readjustment. This allows small businesses to quickly and conveniently switch to the production of a new product.
Description of conductors
Let's start with the concept of conductor is a so-called template, the use of which allows for comfortable and ultra-precise drilling.
Moreover, you can drill either perpendicular to the surface or at any angle. If you use a conductor, then you do not need any special qualifications to do complex calculations, make markings where the holes will be, which saves a lot of time.
Areas of application
As we can see, due to the versatility and simplicity of their design, conductors are widely used in different areas activities.
Mechanical engineering
In the mechanical engineering industry, they are used for drilling holes in various workpieces made from common materials. Conductors are used that repeat the drawing with exact observance of all dimensions. Also used when drilling holes of mixed type is required.
Furniture production
The most important distribution of conductors was in furniture production. Furniture conductors are used for installing fittings, assembling furniture and many other technological processes.
At the same time, furniture assembly is neat, precise and fast. A large amount of furniture contains dowels, which must be installed very precisely and there is no need for a conductor.
The most common jig for dowels is doweling. They mainly use overhead conductors made of lightweight materials.
Construction
Another area in which jigs are widely used for drilling holes is construction. They are used to drill technological holes in building structures, For example, .
Main advantages of use
You can buy a conductor or make it yourself.
But before choosing a model, you should decide for what tasks it will be used and, based on all this data, you should choose the type and design of the tool.
So why should you use jigs for drilling holes?:
- Intuitive use that does not require professional skills.
- Low price of the device, as well as the possibility of self-production.
- Saves a lot of time.
- There is no need to mark the surface to be treated using.
- Maintain precision when drilling.
A jig for drilling holes is an integral part not only of production, but it will also be useful in home life.
How to make a conductor with your own hands
Since there are many types of conductors, we will consider original design and analogue respectively. And so let's begin.
Jig for perpendicular drilling
Its main purpose is to produce holes in thick workpieces at an angle of 90. In essence, it is a set of bushings combined in one body. Usually these are overhead conductors, which are widely used in furniture assembly.
Just place the device on the surface and you can start drilling right away, without punching. There is one drawback: the device should be held tightly, especially at the beginning of work. Because vibration can cause the device to shift.
This type of conductors can be made with your own hands.
- You can use it as a base wooden block, a piece of PCB, reinforcement with square section 10x10 mm.
- We treat the surface well, clean it and begin marking.
- Please note that the center of the holes should be 8 mm. from the edge of the workpiece. This is due to the fact that 8 mm. this is half the thickness of the sheet.
- According to standards, there should be exactly 32 mm between the centers of the holes.
- After that, we make holes with a diameter of 5 mm in these centers.
A homemade conductor can be used, but for more convenient use a stop should be constructed; for this, metal 23-25 mm wide is used. and 1 mm thick, after which the sheet is bent at an angle of 90 and attached to the jig. Also, bushings of different diameters can be inserted into the base of the conductor.
Conductor for pipes and cylindrical blanks
Everyone knows that making a hole in a sloping surface is problematic; the end of the drill constantly jumps off. This type of conductors is fixed in a given position and allows you to work with high precision.
This type of conductors can be made quickly and independently.
- To do this, we need a block of hard wood, loosened diagonally. And we attach a piece of plywood to the edge of the block using self-tapping screws.
- Then we make holes of the required diameter in the wooden block.
That's it, the conductor is ready for work. To make the holes less likely to break, they can be reinforced with metal sleeves, which are made from round pipes of different diameters.
Jig for drilling holes at an angle
This type of drilling is rarely used.
It should be noted here that in metal products this type of hole is made only with a milling cutter. And as for wooden products, then there are ready-made solutions in the form of kits.
It’s easy to use these jigs; we press the workpiece tightly to the base, set the specified height, and as a result we get smooth and beautiful oblique holes at an angle. Yes, if we don’t need a through hole, then don’t forget to put a stop ring on the drill itself.
On your own this type The devices are difficult and problematic to manufacture. There is enough simple ways and options, but they are not accurate. So, for example, a drill is placed on a prepared inclined surface and our workpiece is drilled at the resulting angle, as we understand, the accuracy suffers greatly.
Jig for drilling holes for dowels
Their main purpose is to maintain the alignment of the holes, into which dowels will subsequently be installed. That is, when you apply the jig to both sides of the product, you get a perfect joint.
As you understand, this type of conductors can be made independently. If you have a flow of workpieces with the same geometry, it will be convenient for you to use an overlay template. It is advisable to use hardboard or other material as a template. transparent material(plastic).
We mark and drill holes. It is advisable to drive brass or copper tubes into the holes so that the drill does not break the calibration hole.
Universal device
When you use blanks various forms and sizes, then you will need universal device. The most interesting thing is that this device can be made from scrap materials.
- For this we need plywood, about 15 mm thick.
- We make three identical blanks.
- We make holes along the edges into which dowels are installed as legs.
- We make one hole in the middle, which we reinforce with a metal tube.
- Let's make three metal strips with symmetrically located holes, they will serve as a shoulder. These shoulders are responsible for the linearity of the holes of the future conductor.
- We make cuts in the plywood blanks and install metal shoulders, securing everything. Our universal self-centering jig is ready.
Conclusion
Any universal conductor for drilling holes is made to save time and money. Whether you make it yourself or buy it ready-made in a store is up to you to decide.
