Broca KWB 1598400 1,6 cm giro a la derecha

Mandrel for HSS bi-metal holesaws with integrated HSS pilot drill. 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

The mandrel combines a hardened shank for secure clamping with an HSS pilot drill to start and guide the holesaw accurately. Its right-hand rotation design is compatible with standard power drills and helps reduce wobble and material damage during cutting. The integrated pilot drill simplifies setup and speeds up the drilling process.

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.
