930 Series

Tool 931i1248B

Tight workholding slots demand precision geometry and surface finish. The 931i1248B delivers a 120-degree included angle with R0.005" corner radius for dovetail profiles where stress concentration matters.

The AlTiN coating handles the interrupted cuts typical in slotting operations while maintaining edge sharpness through steel and aluminum.
Two flutes balance chip evacuation with rigidity on this 0.1875" cutting diameter.
The corner radius serves two functions: it reduces stress concentration at the dovetail root and extends tool life by eliminating sharp edge breakout.
The 0.0787" neck diameter provides clearance for deeper slots while maintaining sufficient strength for the cutting forces.
Designed for steel, aluminum, and most machinable metals in workholding applications where fatigue resistance and dimensional accuracy both matter.
