970 Series

Tool 970i2404B

Standard end mills don't cut side slots below a shoulder. The 970i2404B does.

A solid carbide keyseat cutter for keyways, side slots, and profile features in steel and iron where reach into the part geometry is the constraint.
Eight flutes balance surface finish against chip evacuation in ferrous materials.
More cutting edges mean shorter chips and better walls on interrupted cuts.
The 0.0625" cut width produces clean slot walls while the 0.1875" neck diameter provides the reach needed for shouldered features.
Conservative radial engagement is the right call since the neck diameter, not the 0.375" cutting diameter, determines rigidity limits.
AlTiN coating handles the heat buildup from steel cutting operations.
The aluminum content maintains hardness at elevated temperatures while titanium provides the base wear resistance.
