970 Series

Tool 970i1204B

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.
Six flutes balance surface finish with chip evacuation in the 0.0625" cut width.
More flutes would pack chips, fewer would leave tool marks in steel applications.
The 0.0938" neck diameter is the stability constraint here, not the 0.1875" cutting diameter.
Conservative radial engagement keeps deflection in check when cutting below shoulders or into pockets where spindle access is limited.
AlTiN coating extends tool life in steel and iron by managing heat buildup during interrupted cuts.
The aluminum content forms a protective oxide layer that maintains edge sharpness through thermal cycling.
