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
Tool Bits
- screwdriver bits and bit holders
- drill bits (shafts typically limited to 10 mm)

Lukas has a Bosch PSR 960 you might be able to use soon, provided it can be fixed up!
There are two batteries, but one is quite old and only holds its charge for a very short time. It should really be upgraded to Li-ion cells[1] or a corded pack soon...
Technical Data
- battery: 9.6 V, 1.25 mAh (old one: 1.2 mAh), 4/5 Cs NiCd
- "Cs" might refer to discharge capacity, would be 5 to 6.25 A - power consumption as verified with a lab power supply: 2.5 A without resistance/5 A on torque setting 3 out of 5
- charger: "AL 1404", 7.2 to 14.4 V, 400 mA -> 3 h charging time for above packs
