970 Series

Tool 970i3204C

Standard end mills can't reach into tight geometries for side slots. The 970i3204C gets there.

An eight-flute keyseat cutter designed for steel and iron applications where precision matters more than speed.
The 0.0625" cut width produces clean slot walls in keyways and profile features below shoulders.
Eight flutes distribute cutting forces across more edges, reducing vibration when the 0.25" neck diameter limits rigidity.
TiB₂ coating handles the heat generated in ferrous materials while maintaining sharp cutting edges longer than uncoated tools.
The coating's low friction properties help with chip evacuation in the narrow slot geometry where chips have limited escape routes.
Conservative feed rates work best here.
The neck diameter controls stability, so let the multiple cutting edges do the work rather than forcing heavy cuts.
