How to choose a device for precision drilling holes in wood?

Drill attachments allow you to perform a variety of functions, for example, sharpening drills, working strictly perpendicularly or at a certain angle. This article describes the basic attachments that will help replace expensive tools and save a lot of money.

Features of choice, pros and cons of devices

There are quite a few different accessories available for drills. They can be used for cutting metal products, drilling in difficult places, and lapping valves. There is also a device for accurately drilling holes in wood and sharpening drills.

In many cases, a drill equipped with additional attachments allows you to replace expensive equipment, such as a lathe, hammer drill, metal cutting device, and others. This significantly reduces the cost of work. But it is worth considering that the drill attachment will fully replace the corresponding tool only in everyday life.

If you use the device frequently, the attachments will quickly wear out, and the tool itself may suffer. Therefore, we can say that attachments have both pros and cons. Clear advantages include:

• significant savings on the purchase of equipment;
• convenient storage - virtually no space is wasted;
• no need to maintain tools, clean or lubricate;
• a very large selection of attachments - there are devices for even drilling, limiters and many others.

But it is important to understand that with regular use, the attachments wear out quickly. You can make a drill stop yourself or make other accessories. However, if you need to carry out work on an industrial scale, you should use professional tools, for example, a lathe or a metal cutter.

Types of nozzles

There are several types of nozzles, they are divided depending on the purpose and design features. For example, if you need to use a drill for hard-to-reach places, install an angle adapter. And for vertical drilling, a stand is used. These and other attachments are described in more detail below.

For drilling in difficult places

If the place is difficult to reach, you will need a device for even drilling. It is needed in cases where you have to work inside narrow containers, for example, in a box. Experienced craftsmen recommend using a corner adapter. This is an L-shaped adapter. It allows you to maintain torque and number of revolutions, so there will not be much difference with the normal mode.

If you don’t have an adapter at hand, you can use a direct drilling device such as a drill stop. Essentially, this is a locking nut that rests against the wall, after which you need to stop working with the drill.

For working at right angles

It is often necessary to carry out work at a strictly right angle.In these cases, a vertical drill bit works well. This is a device based on a supporting frame. A groove is attached to it, which directs the movement, as well as a bushing. The drill clamp itself is mounted on this sleeve. The operator moves the sleeve down and up, holding a special handle. Thanks to this, the drill is installed strictly perpendicular to the surface.

This 90 degree angle drill attachment is made up of metal parts. Electromagnetic stands are also available. If desired, you can make a guide yourself using wooden blanks.

For working from different angles

There are different attachments for special tasks, such as a drill attachment for routing. But much more often they use attachments that allow you to work at different angles (not straight). They are also based on a guide frame - one or two. They are fixed at certain angles, which makes it possible to obtain a high-quality hole.

You can, for example, use an electric drill attachment that will drill at an angle of 45 degrees. Also often used are homemade stands that allow the clamp to rotate.

For lapping valves

There is also a useful device for a drill that prepares engine valves well for operation. These suction cups replace an expensive air machine. They got their name because of the way they are fastened. They are attached simultaneously to the drill and the rod.

The tool should operate at low speed. It is also recommended to use lapping paste, but only in minimal quantities. You only need to press lightly - then the grinding will take place correctly.

For sharpening drills

There is also a special drilling attachment for the drill, which allows you to sharpen drills. Replaces circular saw, lathe and other bulky tools. It resembles a round disk with many holes of different sizes.

There is a sharpening stone inside this disc. If you turn on the drill, it begins to rotate rapidly. All that remains is to insert the drill and process it. In this case, it is necessary to carefully select the diameter of the disk, since due to a discrepancy, the drill can become dull and even irreparably damaged.

A device for perpendicular drilling with a drill and sharpening drills are the most popular. They perform functions that are necessary for almost all specialists, including at home.

For working with screw piles

Such piles can only be driven with a particularly powerful drill - from 1000 W. But along with good performance, the rotation speed should not be very high - literally within 600. To combine these requirements, electric drill attachments such as multipliers are used. You can buy them in a store or make them yourself - the quality will not suffer from this, but in appearance they will not be so attractive.

Turning fixtures

A device for perpendicular drilling with a drill is very often used. Also in some cases turning accessories may be needed. These are special machines with a vice that tightly fixes the tool. It is better to purchase universal devices that are suitable for both a drill and a screwdriver.

Milling attachments

There is also a milling attachment for a drill - you can purchase it or make it yourself from wood.It is a compact device with which you can work with wooden workpieces, make corner joints, and mill grooves at the ends.

Devices for drilling and other purposes can be useful even in everyday life. Therefore, it is recommended to purchase them in advance, taking into account different tasks. A device for drilling with a drill at a right angle is especially in demand, but attachments for sharpening drills, as well as for working at different angles, may also be needed. If you plan to use the tool quite often, it is better to purchase a professional device or machine.
