970 Series

Tool 970i4016B

Standard end mills can't reach into shoulders to cut side slots. The 970i4016B gets there.

Eight flutes in a 0.625" cutting diameter generate the surface finish steel and iron applications demand while maintaining the narrow 0.25" cut width needed for precise keyways.
The 0.3125" neck diameter provides adequate rigidity for the cutting forces while allowing clearance into restricted part geometries.
AlTiN coating handles the heat generation from continuous side cutting in ferrous materials.
The coating's aluminum content forms a protective oxide layer at elevated temperatures, extending tool life when cutting steel where heat buildup is inevitable.
Eight flutes mean more cutting edges sharing the load, reducing individual edge stress.
Conservative radial engagement keeps cutting forces within the neck's capability.
The geometry does the work.
