Difference between drill and drill.

Drill and drill refer to cutting tools. When working with each of them, depressions or holes of a cylindrical shape are obtained. At first glance, this suggests that the drill and drill are virtually indistinguishable. However, the answer to the question of how a drill differs from a drill is not so simple. Each tool has many varieties, but you can clearly define what belongs to drills and what to drills. There is one important criterion for this. So, first things first.

What is drilled and what is drilled?

Using these cutting tools, you can make holes or recesses in almost anything:

• wood and materials based on it (chipboard, OSB, fiberboard, etc.);
• plastic;
• metal;
• stone;
• ceramics;
• brick, concrete and so on.

The difference between a drill and a drill is that it is usually used for processing durable, non-shock-absorbing materials - concrete, stone. A drill is better suited if you need to drill softer and more elastic arrays: wood, plastic. Metal, although it has great strength, the material is elastic, springy, so it is also processed with a drill. What this is connected with - we will consider below.

Comparison

Drills have a large number of varieties. Some are designed exclusively for processing wood and plastic, others are universal and can be used when drilling holes even in brick and concrete, when the use of a drill is impractical for some reason. They differ in the design of the cutting edge, the number of chutes for removing chips or other removed waste (concrete dust, etc.). Processing of the material by drilling is carried out as follows: the drill rotates at high speed around its axis, the cutting edge enters the material to be processed, and waste is discharged through the chutes.

Drills of a special design are used for drilling large-diameter holes, which among specialists have the slang name "crown". They are used for processing soft materials (wood, plastic) and are hollow drills. For the processing of tiles, drills of a special type are also used, which have received the unofficial name "feather". These drills usually have a diameter of no more than 10 millimeters.

The fundamental difference between a drill and a drill is that it is designed for processing materials in a shock-rotational way. That is, the drill, during operation, performs not only rotational (around the axis), but translational (along the axis) movements. This method of processing makes it possible to punch holes in durable materials, the processing of which with drills is impossible or very difficult. The drill bit usually has a slightly rounded working edge to increase its working life. With the help of a drill, it is possible to punch holes up to 1000 mm (1 meter) long, however, the work is carried out in three stages with a gradual increase in the penetration depth.

Typically, the drill and drill differ in the type of shank (the part of the tool that is mounted in the chuck). The drill is usually simply clamped with three jaws. And for the drill, there is a special chuck that allows the working tool to move along the axis of rotation. There are electric drills with a chiseling function, in which a conventional chuck is used, but practice has shown that, in comparison with hammer drills, where a drill is used, they are ineffective.
