930 Series

Tool 931i2412B

Tight workholding slots demand precision geometry without the stress concentrations that lead to premature failure. The 931i2412B handles 30-degree dovetail profiles in steel, aluminum, and most machinable metals where fatigue resistance matters.

The R0.01" corner radius at the dovetail root eliminates sharp stress concentrators that would otherwise initiate cracks under cyclic loading.
Three flutes balance surface finish with chip evacuation in the constrained cutting environment typical of slotting operations.
AlTiN coating extends tool life in steel applications by maintaining edge sharpness at elevated cutting temperatures.
The 0.2362" neck diameter provides clearance for the full dovetail profile while maintaining adequate tool rigidity for interrupted cuts.
This geometry works for workholding slots, T-slot preparation, and undercut features where both the included angle and root radius are specified.
