970 Series

Tool 970i1603C

Standard keyseating gets unstable when the neck diameter drops this low. The 970i1603C handles it.

Six flutes on a quarter-inch cutting diameter distribute cutting forces across more edges, reducing individual flute loading when the 0.125" neck becomes the weak point.
TiB₂ coating adds surface hardness without building thickness that would compromise the already tight clearances in steel and iron keyway operations.
The 0.0469" cut width produces precise slot dimensions while the narrow neck reaches into shoulder areas where larger tools bind.
Steel and iron work generate heat that breaks down uncoated edges in these confined cuts.
The coating extends tool life by maintaining edge sharpness longer under the interrupted cutting conditions typical in keyseat operations.
Conservative speeds keep the thin neck from deflecting while the multiple flutes maintain surface finish.
