930 Series

Tool 931i1212B

Tight workholding slots demand precision geometry that won't chip out on entry or leave poor surface finish. The 931i1212B handles 30-degree dovetail profiles in steel, aluminum, and most machinable metals where dimensional consistency matters.

The R0.005" corner radius at the dovetail root reduces stress concentration in the finished profile while strengthening the cutting edge against chipping during interrupted cuts.
AlTiN coating extends tool life in steel applications by maintaining edge sharpness through higher cutting temperatures.
The 0.1181" neck diameter provides clearance for deeper cuts while maintaining rigidity in this 0.1875" cutting diameter size.
Two flutes balance chip evacuation with surface finish quality.
Works for T-slot preparation, fixture slots, and undercut profiles where the corner radius specification is called out on the print rather than a sharp corner.
