What else needs to match?
Bosch Professional GKF 600: buying checks
This search is for cutters with a 1/4 inch shank used with the documented UK collet. Cutter diameter and other limits still apply.
- Match the cutter shank exactly to the approved collet actually installed; 6 mm is not 1/4 inch and 12 mm is not 1/2 inch.
- Check maximum cutter diameter, insertion depth and the chosen base in the tool manual.
- Keep the selected tool speed within the cutter’s rating and follow the maker’s material and feed guidance.

Use 1/4 inch shank cutters with the supplied UK collet. A 6 mm or 8 mm cutter requires its own approved matching collet.

- Check maximum cutter diameter, insertion depth and the chosen base in the tool manual.
- Keep the selected tool speed within the cutter’s rating and follow the maker’s material and feed guidance.
