The choice of a drill depends on the specifics of the upcoming work. Sometimes you can do with a percussion drill, and sometimes you need a more professional tool. To choose a drill, you need to know some features of the various types of this tool.

Types of Drills

Kinds

Two types can be divided:

  • conventional drill with a blow (screwdriver);
  • hammer drill.

A percussion drill is a less powerful tool than a hammer drill. Her drilling function is the main one. It is great for working with materials such as steel and wood. Tiles are also drilled with a drill. In order to work with not very hard materials at home, an ordinary drill is quite suitable.

The puncher is a professional tool. The drilling function is not the main one. Usually, during operation, the shock function does not turn off. The puncher is an excellent tool for working with concrete. With its help, holes of large diameter can be made in concrete walls.

A simple drill can work where a small hole diameter is required. For example, it can produce holes in concrete with a diameter of up to 13 mm, in a tree. up to 20 mm, and in steel. up to 8-9 mm. Larger holes require another, more powerful tool.

Specifications

Drills have three main characteristics by which they differ.

  1. Drilling diameter. This indicator has already been discussed above. In order for the drilling diameter to be high, a more powerful tool must be selected.
  2. Rated power.
  3. The number of revolutions per minute.

It is a mistake to assume that the power of the drill depends on the number of revolutions per minute. In fact, the opposite is true: the maximum speed of rotation of the drill depends on power.

The choice of a drill / driver

Working conditions

The drill / driver has two main functions:

  • drilling;
  • twisting and unscrewing various fasteners.

Each model may have one of two functions prevailing. Therefore, choosing a tool, you must immediately decide what will be a priority: drilling or loosening screws. The choice of a drill / driver depends on the specifics of the upcoming work.

The most convenient version of a drill / driver is a cordless drill. It can function where it is impossible to bring an electric cable. During the construction of a new house, for example, there may simply not be access to the mains nearby. Drill with the battery will save the situation.

How to determine what the drill is more focused on. drilling or twisting? To do this, look at such characteristics as:

  • number of revolutions per minute;
  • torque.

If the tool has about 1000 revolutions per minute or more, then this is a great drill for drilling. If the indicator is closer to 400-500, then this is definitely a screwdriver.

Cordless drill When choosing a model with a battery, great attention should also be paid to the battery itself. There are many different devices of this type on the market today. Batteries are:

  • nickel cadmium;
  • nickel. metal hydride;
  • lithium ion.

The nickel-cadmium battery should be removed immediately. It is not environmentally friendly. Because cadmium is a harmful allergen. Nickel. metal hydride devices are not bad. Lithium-ion batteries are the highest quality, but there is so far little tool with such devices on the Russian market.

What else to consider

Screwdriver

Electric drill screwdriver works by pulling the trigger. The stronger the master clicks on it, the higher the speed of the drill. Working with an electric drill is tiring, because the hand is overstrained. When choosing, it is better to buy a professional tool that is maximally adapted for comfortable work.

The choice of an impact drill depends not only on the type of work, but also on its scale. An unprofessional drill cannot function continuously. She needs constant rest. Therefore, if repair is foreseen, it is better to take a professional tool. Of course, it is more expensive. But he will not constantly fail.

The best power tools are produced in Western countries. The fact is that there is a very highly developed segment of highly skilled workers. Almost all new developments in the field of electrical devices come from there.
