How to use

Secure the appropriate diameter bimetal hole saw onto the holder’s M12 thread and tighten according to the hole saw manufacturer’s instructions. Insert the 13 mm HEX shank into the drill chuck or adapter and clamp firmly. Position the pilot drill on the intended drilling point and start drilling at low speed to establish the pilot hole, then increase speed as required. Maintain steady pressure and allow the tool to cut without forcing to prevent overheating and wear.

Usage recommendations

Use cutting lubricant when drilling metal, keep RPM appropriate for the material and hole diameter, and replace the carbide blades if wear reduces cutting quality. Ensure the drill and holder are compatible with the machine and follow safety practices including eye protection and secure workpiece clamping.
