How to use
Mount the diamond core bit securely to a compatible core drill using the 1 1/4" threaded connection. Position the drill at the marked drilling point and ensure proper alignment before starting.

Withdraw the core bit periodically to clear debris and inspect the segments for wear.
Usage recommendations
Use appropriate personal protective equipment including eye protection, hearing protection and a dust mask or extraction system when dry drilling. For best segment life and hole quality, use water cooling and avoid excessive side loads. Match feed speed and rotational speed to the material hardness and the drill motor specifications.
