930 Series

Tool 931i1636B

Tight spaces demand precision geometry. The 931i1636B handles 90-degree dovetail cuts in confined areas where larger tools won't fit, with a 0.25" cutting diameter and reduced 0.114" neck for clearance around complex workholding fixtures.

The R0.01" corner radius at the dovetail root reduces stress concentration in the finished profile.
This matters when the workholding slot will see repeated clamping loads or vibration during machining operations.
The radius also strengthens the cutting edge at the profile transition, extending tool life in interrupted cuts.
AlTiN coating provides wear resistance in steel applications while maintaining good lubricity in aluminum.
Two flutes balance chip evacuation with surface finish in both ferrous and non-ferrous materials.
The 90-degree included angle matches standard workholding requirements.
