varieties and their use + Video Sometimes at home you need to make holes in the workpieces for wood, metal, chipboard or other material.

And the presence of a screwdriver does not save and does not allow making holes strictly at an angle of 90, we are not talking about oblique holes at various angles.

To facilitate material handling, use a jig for drilling.

These devices are widely used in the furniture industry.

General information about conductors

Today in our article, we will talk about the types of conductors, their scope and opportunities to make your own.

Types of conductors

It should be noted that these devices are used not only for drilling holes, but also when milling, turning and cutting are performed.

Consider the main types of devices.


This type of jigs is superimposed on top of the workpiece. It can lie either freely or be crushed with bolts or clamps. They are appreciated for their simplicity of design and low cost.

bushings that adjust the pivot axes in the horizontal, vertical and inclined planes. These models of jigs are designed for drilling cylindrical products.


The name speaks for itself, the conductor is not attached in any way, it is simply applied where a hole needs to be made.


Able to make holes in several planes.


They do not have rotary elements, they are able to move the part and process the same type of workpieces.

These conductors have this function as changeover. 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 - this is the so-called template, the use of which allows for comfortable and ultra-precise drilling.

Moreover, you can drill both perpendicular to the surface, and at any angle. If you use a jig, then you do not need special qualifications, do complex calculations, make markings where there will be holes, which saves a lot of time.

Fields of application

As we can see, due to the versatility and simplicity of their design, conductors are widely used in various fields of activity.

Mechanical Engineering

In the mechanical engineering industry they are used for drilling holes in various blanks made from common materials. They use conductors that repeat the drawing with exact observance of all dimensions. Also used when mixed hole drilling is required.

Furniture production

The most important distribution conductors received in the furniture industry.

Furniture conductors are used for installing fittings, assembling furniture and many other technological processes.

At the same time, the assembly of furniture is neat, accurate and fast. A large number of furniture, contain dowels, which must be installed very accurately and here without a conductor anywhere.

The most common dowel conductor is doweling. They mainly use overhead conductors made of lightweight materials.


Another area in which conductors are widely used for drilling holes is construction. With their help, drilling of technological holes in building structures is carried out, for example, when installing sandwich panels .

Solves a wide range of tasks, especially in drilling metal pipes. Allows you to clearly maintain perpendicularity when drilling. Also used when drilling holes in tiles.

Main advantages of using

The jig can be bought or made by yourself.

But before choosing a model, you should decide for what tasks, it will be used, and on the basis of all this data, you should choose the type and design of the tool.

So why use jigs to drill holes :

  1. Intuitive use that does not require professional skills.
  2. Low price of the device, as well as the possibility of self-production.
  3. Saves a lot of time.

  4. The surface to be treated does not require markings using Construction Levels .
  5. Observance of accuracy when drilling.

A jig for drilling holes is an integral part not only of production, but also will be useful in home life.

How to make a conductor with your own hands

Since there are many varieties of conductors, we will therefore consider the original design and analogue, respectively. So, let's begin.

A jig for perpendicular drilling

Its main purpose is to get holes in thick workpieces, at an angle of 90. In fact, it is a set of bushings combined in one body. Usually these are overhead conductors, which are widely used in furniture assembly.

It is worth attaching the device to the surface and you can start drilling immediately, without punching. There is one drawback, the device should be held firmly, and especially at the beginning of work.

Because vibration can move the device.

This type of conductors can be made by hand.

  1. As a basis, you can use a wooden block, a piece of PCB, reinforcement with a square section of 10x10 mm.
  2. We process the surface well, clean it up and proceed to the marking.
  3. Please note that the center of the holes must 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 chipboard sheet.

  4. According to standards, there should be exactly 32 mm between hole centers.
  5. After that, in these centers we make holes with a diameter of 5 mm.

A self-made jig can be used, but for more convenient use, an emphasis should be designed, for this they use metal 23-25 ​​mm wide. and 1 mm thick. , after which the sheet is bent at an angle of 90 and attached to the conductor. Also, bushings of different diameters can be inserted into the base of the jig.

Jig for pipes and cylindrical workpieces

Everyone knows that making a hole in a sloping surface is problematic, the end of the drill constantly jumps off.

This type of jigs is fixed in a given position and allows you to work with high accuracy.

This kind of conductors can be done quickly and independently.

  1. To do this, we need a block of hardwood, loose on the diagonal. And we attach a piece of plywood to the edge of the bar with self-tapping screws.
  2. Then we make holes of the required diameter in a wooden block.

That's all the conductor is ready to work. In order for the holes to break less, they can be reinforced with metal sleeves, which are made of round pipes of different diameters.

Jig for drilling holes at an angle

This type of drilling is rarely used.

Suitable when holding a drill or screwdriver at the desired angle is almost impossible.

It should be noted here that in metal products this type of holes is made only by a cutter.

As for wooden products, there are ready-made solutions in the form of kits.

It's easy to use these conductors, 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 do not need a through hole, then it is unforgettable to put a stop ring on the drill itself.

It is difficult and problematic to make this type of device on our own. There are quite simple methods and options, but they are not very accurate.

So, for example, a drill is placed on a prepared inclined surface and our workpiece is drilled at the obtained angle, as we understand the accuracy suffers greatly.

Conductor for drilling holes for dowels

Their main purpose is to maintain the alignment of the holes, in the future into which the dowels will 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 stream of workpieces with the same geometry, it will be convenient for you to use an invoice template.

It is desirable to use hardboard or other transparent material (plastic) as a template.

Marking and drilling holes. It is advisable to drive brass or copper pipes into the holes so that the drill does not break the calibration hole.

Universal attachment

When using workpieces of various shapes and sizes, you will need a universal attachment. The most interesting thing is that this device can be made from scrap materials.

  1. For this we need plywood, about 15 mm thick.
  2. We make three identical blanks.
  3. Along the edges we make holes in which the dowels are installed as legs.
  4. We make one hole in the middle, which we reinforce with a metal tube.
  5. We 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.

  6. We make cuts in plywood blanks and install metal shoulders, fix everything. Our universal self-centering jig is ready.


Any universal jig for drilling holes is made to save time and money. Whether you make it yourself or buy it ready-made in the store, it's up to you to decide.

It should be noted here that for one time or for home use, it is enough to buy the simplest jig, and if you are constantly practicing, then you should drip on professional equipment for drilling holes, which is expensive (Wolfcraft).

If you decide to buy equipment, then it should be done only in official and certified points where you will receive a full guarantee of quality!

When working with conductors, you must follow the safety rules. Good luck with your choice.
