930 Series

Tool 930i2412B

Sharp corners on dovetail cutters chip out when interrupted cuts hit fixture bolt holes or material transitions. The geometry demands it. You're undercutting at angles where chip evacuation fights against the cut direction.

The 930i2412B addresses this with a 30-degree included angle that balances undercut capability with structural strength.
Three flutes provide the surface finish fixture work requires while maintaining rigidity in the 0.2362" neck section.
Sharp corners maximize the crispness of workholding slot edges where precise fit-up matters.
AlTiN coating handles the heat buildup that occurs when chips pack against the undercut geometry in steel and aluminum applications.
The coating extends tool life in interrupted cuts where thermal cycling would otherwise cause premature failure.
Applications include fixture plate prep, T-slot manufacturing, and any undercut geometry a standard end mill cannot physically reach.
