How to use

Secure the drill bit in the rotary hammer according to the tool manufacturer's instructions, ensuring the correct shank type and a firm lock. Mark the drilling point, start at low speed to position the tip, then apply steady pressure while allowing the hammer action to do the cutting. Periodically withdraw the bit to clear dust and prevent clogging; for deep holes, pull the bit out more frequently. Use appropriate personal protective equipment, including eye protection, hearing protection and a dust mask when drilling masonry or concrete.

Recommendations

For best results when drilling hard materials, maintain a moderate feed pressure, avoid excessive side forces, and replace the bit if wear reduces cutting efficiency. Match the bit diameter to fixings and anchors specified for 5 mm holes, and use a drill with sufficient impact energy for durable performance.
