Cordless drills are very versatile tools and should not be missing from any workshop. Besides drilling, as the name implies, they are mostly used for driving screws ("electric screwdriver").

Here's a nice video about the internal mechanics of a typical drill!

Proper Use

Please follow these simple guidelines to avoid damage to your screws, material, or the drill itself:

• the torque (DE: Drehmoment) can typically be set with the ring before the chuck
  • better start out too low than to round your screw in the first try - wood may also be damaged if screws (especially self-tapping/"Spax") are inserted too deep
  • the drilling setting at the end of the scale should only be used for drilling, it creates way too much torque for screws and screwdriver bits!
• there may also be variable speed settings (slider on top)
  • use the slower one (1) for screwing to prevent slipping
  • the higher speed can be used for drilling

Bits

• screwdriver bits and bit holders
• drill bits (shaft diameter typically limited to 10 mm)

Lukas has a Bosch PSR 960 you might be able to use!

It has six torque settings and only one speed.

Power Supply

There used to be two batteries, but one was quite old and only held its charge for a very short time. It was therefore upgraded to a corded pack.

Charger for the intact one: "AL 1404", 7.2 to 14.4 V, 400 mA -> 3 h charging time for the 1.2 Ah pack...
