930 Series

Tool 930i3218B

Sharp corners in dovetail slots create stress concentrations that can crack thin-walled workholding fixtures. The geometry needs to remove material efficiently while the corner treatment needs to preserve edge integrity under the lateral cutting forces that define undercut operations.

The 930i3218B uses a 45-degree included angle to match standard T-slot profiles while maintaining adequate tool strength at the narrow 0.2362" neck diameter.
Three flutes balance surface finish against chip evacuation in the confined cutting zone.
AlTiN coating handles the heat buildup from the sideways cutting action that generates more tool-workpiece contact than conventional end milling.
Sharp corners maximize material removal rates in steel and aluminum applications where fixture walls can accommodate the geometry.
The 0.5" cutting diameter provides sufficient rigidity for interrupted cuts in workholding slot preparation.
