970 Series

Tool 970i4008B

Standard end mills can't reach side slots trapped behind features. The 970i4008B cuts where access matters more than speed.

Eight flutes on a 0.625" cutting diameter generate surface finishes that eliminate secondary operations in steel and iron applications.
The 0.125" cut width produces precise keyway tolerances while the 0.3125" neck diameter provides sufficient rigidity for controlled radial engagement.
AlTiN coating extends tool life in interrupted cuts where heat cycling degrades uncoated carbide – the additional hardness layer maintains sharp cutting edges through multiple thermal cycles.
The geometry favors accuracy over material removal rates.
Conservative speeds and feeds prevent deflection at the neck, which is typically the failure point in slender cutting tools.
Profile work and slot milling in hardened steels benefit from the coating's oxidation resistance above 1500°F.
