Tool 931i0812B
Small dovetail profiles demand precision without sacrificing edge strength. The 931i0812B delivers a 0.125" cutting diameter with 30-degree included angle for tight workholding slots and undercut features where space is limited.
- The R0.005" corner radius at the dovetail root reduces stress concentration in fatigue-critical applications while strengthening the cutting edge against chipping in interrupted cuts.
- Two flutes balance chip evacuation with rigidity on the 0.0787" neck diameter.
- AlTiN coating extends tool life in steel and aluminum by maintaining sharp cutting edges at higher temperatures.
- The coating's aluminum oxide layer forms a thermal barrier that keeps the carbide substrate cooler during extended cuts.
- Designed for steel, aluminum, and most machinable metals in both roughing and finishing operations.
