970 Series

Tool 970i4012C

Standard end mills can't reach into tight geometries for side slots. The 970i4012C gets there.

A 5/8" diameter keyseat cutter designed for steel and iron applications where you need to cut 0.1875" wide slots below shoulders or inside pockets.
The 0.3125" neck diameter keeps the tool rigid enough for controlled cuts while allowing access into restricted areas.
Eight flutes distribute cutting forces evenly across the small engagement zone.
TiB₂ coating handles the heat buildup that comes with cutting steel in confined spaces.
The coating extends tool life when chip evacuation is limited and cutting temperatures climb.
Conservative feeds work better than aggressive ones.
The neck geometry sets the stability limits, not the cutting diameter.
