How to use

Use appropriate drilling mode—hammer mode for concrete and masonry, rotary mode for softer substrates—maintaining steady pressure and avoiding overheating. Retract frequently to clear dust and debris and allow the bit to cool during prolonged drilling.

Recommendations

Use personal protective equipment such as safety glasses, dust mask and hearing protection when drilling. For clean holes and longer bit life, use a vacuum or dust extraction where possible and choose the correct drill speed and mode for the material.
