Adapt the rotation speed of the chuck to the diameter of the drill:
- Small diameter = high speed
- Large diameter = low speed.
The impact function, if your machine has it, means that you can drill into building
materials, for example: stone, concrete, brick... The machine must be fitted with a
masonry drill. (carbide tip)
There are a number of different drill types:
- Wood drill (for drilling into wood)
- Metal drill (for drilling into metal and plastic)
- Masonry drill (for drilling into concrete and brick)
There are various types of battery charger:
- rapid = max. 1 hour
- slow = between 3 and 5 hours
To optimise your working time, it is recommended that you use 2 batteries.
Certain electric screwdrivers have rotary batteries (for example: 180°), in order to
improve the balance of the tool and make it easier to reach certain positions.
The level gauge, if your machine is fitted with one, makes it possible to ensure that
you are working perpendicular to a vertical surface.
The digital display, if your machine has one, shows the preselected settings (for
example, rotation speed)
The lighting function, if your machine has one, makes it more comfortable to work
with in dark environments.
The laser, if your machine has one, produces a beam of light which shows you
where the tool will go.
The battery charge test function tells you how much energy is left in the battery.
