How to use

Select the appropriate cutter size for the required hole, install the pilot bit and secure the arbor into the drill chuck. Engage the QuickLock mechanism to attach the cutter to the arbor, ensuring it is locked before starting the drill. Start drilling at moderate speed to establish the pilot hole, apply steady pressure and increase speed as appropriate for the material. After cutting, retract the cutter and remove the workpiece; allow metal parts to cool before handling.

Usage recommendations

For best results use steady feed and appropriate drill speed for the material being cut. Wear eye protection, gloves and hearing protection as required. When cutting metal, clamp the workpiece securely and clear chips frequently to avoid overheating. Replace worn pilot bits and cutters to maintain hole quality.
