What can I choose from?
A simple electric hand drill can be powered from both the mains and the battery. The first has a higher capacity and the ability to work long and smoothly. Cordless drills are used in places where there is no access to a centralized power grid and during work, when frequent movement around the room is necessary.
The choice of such a device justifies itself when it is necessary to have a mobile, independent tool. The battery requires constant recharging, so experienced masters use two batteries: while one is running, the second is on charging.
Another version of the unit is a drill electric screwdriver that can both drill and twist / unscrew the screws and screws. Such tools often have small dimensions and power, but this is quite enough to work in a car repair shop and at home. These drills have a reverse function, which allows you to rotate the drill bit in both directions.
Another type of tool - impact drill. It has increased power and the ability to drill even the most durable surfaces. In addition to the standard rotation, the impact drill makes a large number of reciprocating movements, which greatly increase the force of the drill on the surface being processed.
Note! When buying a drill, you should decide for what purposes you need it to choose the most optimal option for the tool.
Selecting the
tool When sorting out the types of drills and their assignments, you should learn some nuances that will help you choose the tool. So, the drill is electric, how to choose? To assist in this matter, consider the following data necessary for the correct selection:
- Power. It is best to choose a powerful drill in order to perform any, even complex work. The market offers devices from 100 watts of power, but it is desirable to choose 350 watts and above;
- An excellent addition will be the ability to adjust the speed( two or three speeds);
- The electric shockless drill has less power than the impactor, so it is more reasonable to take the second option, as this will make it possible to work with hard surfaces;
- Presence of reverse function.
Note! It is beneficial to immediately buy additional accessories that will expand the scope of the drill.
Domestic drill against the import
It remains to be determined only with the fact, to buy an import tool or to support the domestic manufacturer. Domestic instruments have recently improved significantly in design and have received some functions, for example, speed control. But the most important advantage in their favor is still the price, which is 2-3 times lower than imported vehicles. But there are many reasons why the choice often stops on an imported drill.
Firstly, it's reliability, especially for drills with impact, where a quality anti-vibration system is needed. A poor-quality unit after three months of work begins to give signs that it can not withstand the load. Domestic tools are often inconvenient and cumbersome, that is, despite modern design, working with them is still uncomfortable.
Important! It should be taken into account that imported drills are divided into professional and amateur drills.
the drills of our manufacturers often do not include functions that for Western manufacturers have become the norm even for the cheapest devices, for example, the spindle lock button. Also, domestic tools are still equipped with a gear-crown chuck, for which special keys should be used. About such a concept as a suitcase for a drill, our firms have long forgotten, while imported drills are equipped with suitcases, even for the most simple models. These are the main points that influence the choice between domestic and imported instruments.
