How to use

Secure the drill bit in a compatible hammer drill or rotary hammer with the appropriate chuck or SDS connection. Mark the drilling position and start at low speed to establish the hole, then apply steady pressure and increase speed as appropriate for the material. Withdraw the bit periodically to clear dust and chips and prevent overheating. For deep holes, drill in stages if necessary and ensure stable support of the workpiece.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, hearing protection and dust mask. Match drill speed and hammer action to the material being drilled and allow the bit to cool periodically during extended use to prolong service life.
