35° helix geometry

The 35° helix balances cutting-edge support, chip flow, and stable engagement in stainless steel and titanium.

Controlled cutting geometry

End and peripheral cutting geometry is batch inspected, with dimensional reports available.

Precision h5 shank

Shank diameter d uses an h5 tolerance to support secure location, runout control, and repeatable tool changes.

ZrN coating

Champagne-gold ZrN PVD coating for repeat B2B procurement of stainless-steel and titanium tooling.
