970 Series

Tool 970i4012B

Standard end mills can't reach into tight geometries for side slots. The 970i4012B cuts where others won't fit.

An AlTiN-coated solid carbide keyseat cutter designed for steel and iron applications requiring precise side slots below shoulders.
The 0.625" cutting diameter provides adequate material removal while the 0.3125" neck diameter allows access into restricted areas.
Eight flutes balance surface finish with chip evacuation in the narrow 0.1875" cut width.
The AlTiN coating extends tool life in ferrous materials by resisting crater wear at higher cutting temperatures.
This matters when machining steel where heat buildup typically limits performance.
The narrow neck geometry means conservative radial engagement keeps deflection in check during slotting operations.
Built for keyways, side slots, and profile features where part geometry restricts tool access.
