Electric drill is a multifunctional tool with electric drive, which produces work as a result of the twisting and reciprocating motion. However, universality is not always a convenient property for the tool. Therefore, each series of the line of drills is designed for a certain type of work, but all of them are associated with the use of rotational movement of the working body.

Classification and varieties of drills

The whole tool, depending on the version, can have different power, operate in a certain speed range. The device of the cartridge, the diameter of the drill, the additional function of blows to one point - the features of the instruments of this class.

Based on the technical characteristics, the electric drills are distinguished according to the functions performed:

  • shock;
  • screwdriver, wrench, screwdriver;
  • angular;
  • mixer;
  • universal;
  • ordinary.

The impact drill combines two actions. She uses a drill to form a hole. At the same time, when working with a solid material, stone or brick, axial movement is simultaneously reported to the drill. Drilling with simultaneous longitudinal destruction accelerates the work. However, it is impossible to use such a tool on fibrous wood - a split of the canvas will result.

Angle drill is used in cramped conditions where it is not possible to use a linear tool. Rotation is transmitted from the engine through a reducer and a chuck in which a drill is attached. If the gearbox with the cartridge is located with the letter G, the torque is transmitted at an angle and then the drill body itself is parallel to the wall on which the hole is drilled.

Work with a screwdriver in safety goggles. Legs should stand on a stable platform, it is dangerous to make drilling from the ladder.

Low-power devices with a smaller number of revolutions are used, like drills, screwdrivers. A drill with a special attachment instead of a screwdriver is used to twist nuts and screws. This is a tool for furniture collectors, used in small domestic work. If you need to drill a hole in the tree, the screwdriver will cope.

How to determine the class of the tool

Household tools are easier and cheaper. For home use, it is cheaper to buy a network appliance. Rechargeable batteries do not like prolonged inactivity and come into disrepair from the lack of recharging at a critical time. It is recommended to work with household tools no more than 4 hours a day with interruptions for cooling the shell and bearings. When choosing a device, you need to know if a drill with a high speed is more suitable for drilling a tree. Stone and brick are drilled at reduced speeds. Screwing screws require the lowest speed, but there must be a reverse. This will quickly remove the fasteners by changing the rotation of the screwdriver.

The difference between a professional tool

Drills for professional work have significant differences. Nozzles that make an amateur instrument multifunctional, professionals have no honor. Targeted use tool with two speeds. But comfortable grip reduces fatigue. Despite the use of durable and wear-resistant parts, the weight of the tool is reduced. The tool is adapted to work in conditions of high dust or humidity.

Caring for the tool will extend the service life. Never break the wire, make sure that the insulation is secure. After finishing the work, clean the available places with a brush, remove the drill for storage in a dry place.
