That operation of the new tool has pleased with the efficiency and has not led to disappointment, it is necessary to define in advance what volume of work will be assigned to it in what conditions it will be carried out. Proceeding from it, it is also necessary to choose drill.
1. The drill of shock action is applied to drilling of openings in various materials, including, in concrete and also to twisting and screwing of screws and screws. By means of the perforator it is possible to drill openings in very solid materials as stone and the reinforced concrete. And if to equip the tool with special nozzle chisel, then it is possible to use it for removal of ceramic tile.
2. Making the choice between drill and the perforator, consider that, despite the universality, the perforator of the same power will be rather more expensive. Features of fastening in perforator chuck do not allow to use normal drills in work with it that forces to do additional expenses. If need for performance of work, interfaced to drilling over solid materials, at you is absent, then it will be rather simple to buy the hammer drill.
3. Getting drill, it is also worth paying attention to power supply type. It can come from the storage battery or from normal network of 220B. Drills network are simple technically, but they and more powerful, in comparison with battery rooms. However in the absence of access to the power supply network the mobile cordless drills are irreplaceable.
4. Remember that if you have to work with drill only at home where always near at hand there will be socket, it is better to give preference to network drill. The cost of storage batteries and the charging device is about a third of the total cost of the device that will be notable at their failure. Also cordless drill will not be able to cope with opening of large diameter or depth.
5. Pay attention to availability on the badge tool body in the form of double square. It designates that the tool has electric protection which will allow to avoid serious current blow during the work with it. Besides double isolation some drills have special protection against accidental start-up at which pressing of the main start button is confirmed by pressing of additional.
6. The compact and convenient household drill not of the biggest power will become the most convenient for the house. The main advantage of such tool is the small weight and the low price. At right operation it is possible to use drill no more than four hours a day with twenty-minute breaks in work. The professional tool is ready to hours-long daily work. For production of such drill the metallic parts increasing reliability of the body in the conditions of continuous operation are used.
