The KWB 1598400 mandrel is intended for use with compatible bi-metal holesaws and provides a stable connection and precise pilot drilling during hole-cutting operations. It is designed for right-hand rotation and matches standard holesaw setups for general workshop and installation tasks.

Advantages

How to use

Secure the mandrel in the drill chuck and attach a compatible HSS bi-metal holesaw to the arbor following the holesaw manufacturer's instructions. Ensure the pilot drill is centered on the intended drilling point, start drilling at low speed to establish the pilot hole, then increase speed as appropriate for the material. Apply steady pressure and allow the holesaw to cut without forcing to avoid overheating.

Recommendations

Use cutting lubricant when drilling metals to prolong pilot and holesaw life. Check that the drill and mandrel are tight before use and replace the pilot drill if it becomes dull to maintain accurate hole placement.
