How to choose a fixture for precision drilling holes in wood? – Setafi

Drill attachments allow you to perform a variety of functions, for example, sharpen drills, work strictly perpendicular or at a certain angle. The basic attachments that will help you replace expensive tools and save a lot of money are described in this article.

Features of choice, pros and cons of devices

There are quite a few different drill attachments available. They can be used for cutting metal products, drilling in difficult places, valve grinding. There is also a device for precise drilling of holes in wood, sharpening drills.

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

If you use the device often, the nozzles will wear out quickly, and the tool itself may suffer. Therefore, we can say that nozzles have both pluses and minuses. Clear benefits include:

• significant savings on the purchase of equipment;
• convenient storage - practically no space is wasted;
• no need to maintain tools, do cleaning, lubrication;
• a very large selection of nozzles - there are devices for even drilling, limiters and many others.

But it is important to understand that with regular use, the nozzles wear out quickly. You can make a stopper for the drill with your own hands or make other accessories. However, if you need to perform work in an industrial scale, you should use professional tools, such as 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 discussed in more detail below.

For drilling in difficult places

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

If an adapter is not available, you can use a direct drilling device such as a drill stop. In fact, this is a locking nut that rests against the wall, after which it is necessary to stop working with a drill.

For work at right angles

Often it is required to carry out work strictly at right angles. In these cases, the vertical drilling attachment is well suited. This device is based on a carrier frame. A groove is attached to it, which directs the movement, as well as a sleeve. The clamp for the drill itself is also mounted on this sleeve. The operator moves the sleeve up and down, holding on to a special handle. Due to this, the drill is set strictly perpendicular to the surface.

This 90 degree drill attachment is made up of metal parts. Also there are electromagnetic racks. If desired, the guide can be made independently on the basis of wooden blanks.

To work from different angles

There are different attachments for special tasks, such as a milling drill attachment. But much more often they use nozzles 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 a device for an electric drill that will drill at an angle of 45 degrees. Also often used are homemade racks that allow the clamp to rotate.

For lapping valves

There is also such a useful device for a drill, which prepares the engine valves well for work. These suction cups replace an expensive pneumatic machine. They got their name because of the features of fastening. They are attached simultaneously to the drill and the rod.

The tool must run at low speed. It is also recommended to use lapping paste, but only in minimal quantities. You only need to press lightly - then the lapping will be done correctly.

For sharpening drills

There is also a special drill attachment for a 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.

Inside this disk there is a stone for sharpening. If you turn on the drill, it starts to rotate rapidly. It remains only to insert the drill and process it. In this case, it is necessary to carefully select the diameter of the disk, because due to a discrepancy, it is possible to blunt and even permanently damage the drill.

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

For work with screw piles

Such piles can only be driven with a particularly powerful drill - from 1000 watts. But along with good performance, the rotation speed should not be very high - literally within 600. To combine these requirements, use attachments for electric drills such as multipliers. You can buy them in a store or make them yourself - the quality will not suffer from this, but outwardly 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 vise 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 blanks, make corner joints, 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 nozzles 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.
