How to use

Mount the KWB 242644 in an SDS Plus-compatible hammer drill according to the drill and tool manufacturer's instructions. Start drilling at low speed to locate the exact position using the self-centring tip, then apply steady pressure and proceed at the appropriate hammer mode and speed for the material. Periodically withdraw the bit to clear dust and debris and to reduce heat build-up.

Recommendations

Use appropriate personal protective equipment (safety glasses, hearing protection and gloves). Match the drill mode and speed to the material hardness; for best results in deep or hard concrete, use intermittent drilling and clear debris frequently to prolong bit life.
