970 Series

Tool 970i2416C

Standard end mills don't cut side slots below a shoulder. The 970i2416C does.

An 8-flute solid carbide keyseat cutter for steel and iron applications where precise 0.25" slot width matters.
Eight flutes distribute cutting forces across more edges, reducing per-tooth loading and extending tool life in harder materials.
The 0.1875" neck diameter provides necessary clearance while maintaining reasonable rigidity for the 0.375" cutting diameter.
TiB₂ coating handles the heat buildup common in steel cutting operations.
Titanium diboride forms a hard, low-friction surface that stays stable at elevated temperatures.
This combination works particularly well in interrupted cuts where thermal cycling would otherwise degrade uncoated edges.
Conservative radial engagement keeps deflection manageable given the neck constraint.
The geometry prioritizes clean slot walls over aggressive material removal rates.
