How to use

Withdraw the bit periodically to clear debris if drilling deeper holes and allow the bit to cool if it becomes hot.
Usage recommendations
Use appropriate personal protective equipment including eye protection, hearing protection and gloves. For reinforced concrete, confirm rebar position before drilling. Match drill speed and hammer settings to material hardness and hole depth to maximize bit life.
