How to use
Secure the drill bit in a compatible rotary hammer chuck following the tool manufacturer's instructions. Mark the drilling position, use appropriate personal protective equipment, and start drilling at low speed to establish the hole, then apply steady pressure and the recommended hammering action for the material. Retract periodically to clear dust and reduce heat build-up when drilling deep holes. After completing the hole, remove dust before inserting anchors or fixings.
Usage recommendations
Use this bit in rotary hammers that accept the specified bit type and follow the rotary hammer's guidelines for drilling diameter and material. For best results in dense concrete, use controlled feed pressure and periodic withdrawal to evacuate debris. Wear eye, hearing, and respiratory protection when drilling and follow site safety rules.
