35° helix geometry
The 35° helix balances cutting-edge support, chip flow, and stable engagement in stainless steel and titanium.
3ROUG / 4ROUG · ZrN Coated · 3 / 4 Flute · 35° Helix
Roughing tooth geometry is designed for efficient stock removal and reduced cutting load during heavy milling. ZrN-coated options support stainless steel and titanium production where throughput and tool supply consistency matter.
35° helix geometry; available in Ø2.5–20 mm across 23 orderable SKUs.

The 35° helix balances cutting-edge support, chip flow, and stable engagement in stainless steel and titanium.
End and peripheral cutting geometry is batch inspected, with dimensional reports available.
Shank diameter d uses an h5 tolerance to support secure location, runout control, and repeatable tool changes.
Champagne-gold ZrN PVD coating for repeat B2B procurement of stainless-steel and titanium tooling.
