930 Series

Tool 931i3236C

Tight clearances around workholding slots leave little room for chip evacuation errors. The 931i3236C handles these confined spaces with a 0.1969" neck diameter that provides access while maintaining rigidity for the 0.5" cutting diameter.

The R0.01" corner radius at the dovetail root serves two functions.
It reduces stress concentration in the finished workpiece, extending fatigue life in dynamic workholding applications.
The radius also strengthens the cutting edge by eliminating the sharp corner that would otherwise chip under interrupted cuts.
TiB₂ coating increases surface hardness to 3000 HV, extending tool life in steel applications where abrasive wear accelerates at the cutting edge.
The three-flute configuration balances chip evacuation with surface finish in aluminum, steel, and most machinable metals.
