The perforator is the device combining in itself electric drill and pick hammer. By means of the perforator you will be able to drill openings in concrete, without wasting special physical efforts, nerves and plenty of time. If you have started houses repair, time to buy the high-quality tool has come.
Instruction
1. The manual perforator is generally used for destruction of firm surfaces or punching of openings. Therefore when choosing the perforator it is necessary to pay special attention to power as it plays important role in definition of opportunities of this tool. Power of modern perforators is in limits of 450-2000 Watts. And there is no accurate division into categories, it is only possible to tell that the perforator with power up to 900 Watts is household. If power exceeds this digit – the tool is considered professional. For probitiya of thick walls it is better to buy the perforator with power from 1200 Watts.
2. The impact strength of the tool shows with what energy the perforator interacts with wall surface. Speed of operation of the tool and efficiency depends on this indicator. The impact strength is directly proportional capacities and is measured in Joules. For example, the perforator with power of 750 Watts and impact strength of 2.8 Joules is capable to do openings in concrete up to 25 millimeters thick, and the tool with power of 1500 Watts and impact strength of 20 Joules – 52 millimeters. For household use choose the perforator with impact strength of 3-4.5 Joules.
3. There are two types of perforators – vertical and horizontal. In the vertical tool the engine is located perpendicular to shock axis therefore the perforator is similar to the inverted letter L. Such type of the perforator has certain advantage in respect of power and cooling of the motor (professionals choose vertical perforators). In the horizontal tool the electric motor is located parallel to shock axis, such perforator is convenient for work in narrow apertures as it is narrower and extended (it is recommended for household use).
4. Pay attention also to additional characteristics. The reverse allows to carry out the movement of drill in opposite direction that allows to take it easily. The regulator of switching of speeds determines the speed of operation of the tool. The anti-vibration system will help to avoid negative impact of vibration on the person. Soft descent will allow to avoid sharp breakthroughs during turning on of the tool. The stopper of the switch is fixer which helps to avoid constant continence switch finger.
