930 Series

Tool 930i2018B

Sharp corners in dovetail work create stress risers that chip carbide edges, especially in steel applications. The geometry has to handle both the undercut operation and the material's tendency to work-harden under the cutting edge.

The 930i2018B uses a 45-degree included angle with three flutes to balance chip evacuation with rigidity in the reduced neck section.
The 0.1772" neck diameter provides clearance for the undercut while maintaining strength at the critical stress point.
AlTiN coating extends tool life in steel by reducing crater wear and adhesion.
The coating's aluminum oxide layer forms a thermal barrier that keeps the cutting edge stable during interrupted cuts.
Three flutes handle the chip load effectively in both steel and aluminum without packing.
The sharp corner radius maintains precise feature geometry for workholding applications where dimensional accuracy determines clamp effectiveness.
