970 Series

Tool 970i2406B

Standard end mills don't cut side slots below a shoulder. The 970i2406B does.

An AlTiN-coated solid carbide keyseat cutter for steel and iron applications where side slot geometry demands reach into confined part features.
The 0.375" cutting diameter with 0.0938" cut width produces clean, dimensionally consistent slot walls in ferrous materials.
Eight flutes distribute cutting forces evenly while the AlTiN coating handles the heat buildup common in steel machining operations.
The 0.1875" neck diameter becomes your stability constraint, not the cutting diameter.
This geometry requires conservative radial engagement to prevent deflection, but the narrow cut width compensates with efficient material removal per pass.
The coating extends tool life in work-hardening steels where uncoated carbide typically dulls quickly from thermal cycling.
