930 Series

Tool 930i1236C

Sharp corners in dovetail work create stress concentrations that lead to premature tool failure, especially in interrupted cuts where the cutting edge repeatedly engages and disengages the workpiece.

The 930i1236C addresses this with a 90-degree included angle and 0.1875" cutting diameter designed for precision undercuts in steel, aluminum, and most machinable metals.
The TiB₂ coating provides exceptional wear resistance while maintaining the sharp edge geometry required for clean dovetail profiles.
Two flutes balance chip evacuation with rigidity in the 0.0787" neck section, which must be narrow enough to access tight geometries without deflection.
This configuration handles interrupted cuts in workholding fixture manufacturing and T-slot preparation where standard end mills cannot reach the required undercut geometry.
