Practical advice
- Only apply the power tool to the screw/nut when the tool is switched off. Rotating tool inserts can slip off.
After working at a low speed for an extended period, you should operate the power tool at the maximum speed for approximately three minutes without load to cool it down.
When drilling into metal, only use sharpened HSS drills (HSS = high-speed steel) which are in perfect condition. The Bosch accessory range guarantees appropriate quality.
Before screwing larger, longer screws into hard materials, it is advisable to pre-drill a pilot hole with the core diameter of the thread to approx. 2/3 of the screw length.
