Quality products are always well sharpened, so they are tightly fixed on the surface. A large base has a slow drilling speed. Interaction is based on the frictional force between elements. High quality fixtures are usually yellow in color., this shade indicates the presence of titanium dioxide in the alloy. Yellow drills have a long service life in contrast to disposable gray drills.

This category of devices includes auger view of the Lewis drill, which has an improved working part.
Such a tool is considered relevant for the formation of a deep hole, which, moreover, has a large diameter.
Feathers
Similar type of drill for working with wood surfaces used if desired to create a hole with a diameter of less than 25 mm... They are used when there are no strict requirements for compliance with the parameters.

Crowns can have different diameters and a removable base.
Cutters
Milling nozzle not only drills wood, but also makes grooves in it with different configurations. The use of devices of this type is considered the most relevant when complex wood surface treatments are required.

- It is best to drill wood with a feather nozzle at a low rotational speed, which does not exceed 500 rpm. The speed of work is directly affected by the diameter of the future hole: the larger its dimensions, the lower the rotational speed should be.
- In the case when the drill is not long enough to form the hole, the master must use a special adapter. The extension is fixed to the tool holder.
- Before starting drilling, it is recommended to bring the drill to the surface at an angle of 90 degrees. In this case, the location of the sharp protrusion should be concentrated in the center of the future hole.

- The shavings that accumulate in the hole must be gradually eliminated. If there is a lot of sawdust, then you should stop drilling and remove wood waste.
