There are a great many different types of drills. They differ significantly only in external parameters (length and diameter) and the material for which they are made and sharpened. Accordingly, first you need to choose the dimensions - for this it is enough to look at the diameter and length of the screws, anchors, etc., which you are going to fasten into the finished holes. Next, you need to select the appropriate drills for each type of work.

Step 1

For drilling holes in soft materials such as drywall, very soft wood, soft insulation panels, etc., flat pen drills are suitable. They are easy to manufacture and therefore very cheap.

Step 2

For drilling wood and chipboard, there are special drills for wood. They look like conventional twist drills with conventional obliquely sharpened symmetrical heads. With proper use, wood drills serve for a long time, since the work is done with soft material.

Step 3

There is also a special type of drill for metalworking. They have a spiral shape, but unlike wood drills, their head is made of high-strength hardened steel.

Step 4

Special drills are used to drill bricks. They are usually spiral-shaped, dark gray in color, with a reinforced head. Outwardly, they look like victorious ones, but they cannot be used to drill concrete, so don't even try. It is a narrow-purpose tool that does a great job of its function, but fails to do anything else.

Step 5

wall. However, keep in mind: such materials are difficult to work with and by themselves will blunt any tool. Even with a good quality drill, it will be difficult for you to make holes in concrete. If you need to drill more than three or four holes, it is better to stock up on several drills, since a blunt head will not cut into a wall, even if you press hard on the drill. The drill will simply rotate at idle, gradually heating up, from which, as a result, it may break. So when dull, they must be replaced in a timely manner.

Step 6

Tile drill. Tile is a very fragile material and can crack easily under excessive stress. Therefore, there are two types of special drills for working with it: with a crown-shaped victorious head and with diamond dusting. Pobeditovoe drills faster, but there is still a chance to accidentally split the tile, so it is better to use it when drilling a workpiece that has not yet been glued. A diamond drill will almost certainly not split the tiles (unless you press down on the drill and not turn on the hammer mode), but the drilling process is very long. In fact, it is a steel rod coated with the smallest diamond coating, and it drills due to the slow abrasion of the surface. By the way, this type of drill is suitable for drilling glass, but this is not necessary in normal household conditions.
