930 Series

Tool 931i0824B

Miniature dovetail profiles demand precision without chipping or poor surface finish. The 931i0824B handles small workholding slots and undercut features in steel, aluminum, and most machinable metals where dimensional tolerance matters.

The 60-degree included angle provides standard dovetail geometry while the R0.005" corner radius eliminates the sharp stress concentration point at the profile root.
This radius also strengthens the cutting edge compared to sharp-corner alternatives, reducing microchipping in interrupted cuts.
AlTiN coating extends tool life in steel applications by providing thermal barrier protection and improved lubricity during chip evacuation.
The 0.0591" neck diameter offers clearance in restricted geometries while maintaining rigidity for the 0.125" cutting diameter.
Two flutes balance chip clearance with edge strength for these precision profiles.
