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!
  • excessive torque does NOT make you screw faster, it really just wrecks stuff...
• there may also be variable speed settings (slider on top)
  • only change when the drill is fully stopped
  • 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)

It has a 2 step metal gearbox for different drilling speeds. A torque limit for screwing can be set with the dial behind the chuck. Please use it to avoid breaking bits and screws due to too much torque! The chuck can hold up to 13mm drill bits.
The drill was donated by Ed and the batteries/charger are sponsored from multiple member donations and our Amazon Smile.

This drill got new batterys.
Please be aware that the charger can be a bit confusing - green light means "not charging" - red light means "charging"
If there is no light, make sure the charger is plugged in and switched on.

AlphaTools AS 18 A

Ciaran's AlphaTools drill comes with two battery packs. The batteries barely hold a charge anymore, perhaps we could upgrade them to use recycled 18650 cells from laptop batteries?

It has two speeds and many torque settings.

The charger can be a bit confusing - green light means "not charging" and you'll have to press the yellow button to start charging a battery!

Private Tools

Bosch PSR 960

Manual:	in the box

Lukas has a Bosch PSR 960 you might be able to use! Unfortunately, its battery has gotten pretty bad.

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

Please do not leave the battery in the charger for more than 3 or 4 hours, the old NiCd batteries will heat up and suffer from quite the memory effect!
