How to use

Install the drill bit into an SDS+ chuck until it locks securely. Select appropriate hammer drill settings for the material and start drilling at moderate feed pressure to allow the carbide tip to cut effectively. Withdraw periodically to clear debris if drilling deep holes and maintain steady alignment to preserve centering accuracy.

Usage recommendations

Use appropriate personal protective equipment (safety goggles, hearing protection and dust mask) and ensure the drill and bit are suitable for the workpiece. For best results in reinforced concrete, start with a pilot position and use progressive feed pressure; replace the bit when wear reduces performance.
