Do not stop your choice on these sets. You have to remember – each operation has its own peculiarity, requires its power, speed and duration of the instrument. The work tool with the overload, or at the limit of its possibilities leads to malfunction. Good universal tool not exist in nature. In good – should only cut or crimp, but only a screwdriver wrapped screws. Stop your choice on the tool with additional features can be used only if their application will be from 15 to 20% of the estimated volume of work.
Another significant change – the presence of reverse rotation. This feature will be especially useful for drills. Without a reversal is impossible to screw or unscrew the screw. And if the drill has a reverse, it is absolutely necessary and another device – speed controller.
If you purchased a powerful and heavy crimp tool, it is desirable that it contains the starting current limiter. Such a tool more smoothly accelerating, not “twitch” in his hands and does not create an unnecessary burden on the electricity grid.
For an instrument with a large release of dust (grinding machines, jig saws, planers, milling machines), it is desirable to have the adapter – a special partrubok on the tool body, with which you can connect the vacuum cleaner.
