970 Series

Tool 970i3206B

Standard end mills don't cut side slots below a shoulder. The 970 Series does.

A solid carbide keyseat cutter for keyways, side slots, and profile features where reach into the part geometry is the constraint.
The 0.5" cutting diameter with 0.0938" cut width produces clean slot walls in steel and iron applications.
Eight flutes provide fine surface finish while maintaining adequate chip evacuation at the narrow cutting width.
The 0.25" neck diameter is the stability constraint here, not the cutting diameter, so conservative radial engagement keeps chatter out of the equation.
AlTiN coating handles the heat buildup that comes with steel cutting, particularly in interrupted cuts where thermal cycling would otherwise wear the edge prematurely.
The coating chemistry works well with ferrous materials where adhesion and crater wear are the primary failure modes.
