ITC Carbide End Mill Corner Radius 4081 - 4 Flute 38° Helix With Roll Relief, Harmonic Fluting, Radius & Coating - Steels & Exotics - 12mm x R1.25

The ITC Carbide End Mill Corner Radius 4081 is a precision carbide milling tool designed for steels and exotic materials. With a 12 mm diameter and an R1.25 corner radius, this 4-flute end mill is optimized for producing accurate radii and clean, consistent cuts on challenging workpieces.

Designed for engineers, machinists, and busy workshops, it delivers dependable performance across contouring, pocketing, and finishing tasks. Its 38° helix, roll relief, harmonic fluting, dedicated radius, and advanced coating work together to promote efficient chip removal, reduced cutting forces, and longer tool life in tough materials.

• R1.25 Corner Radius: Delivers precise radii and smooth transitions, helping maintain tight tolerances and reduce corner chipping on steels and exotic alloys.
• 38° Helix with Roll Relief and Harmonic Fluting: Optimizes chip evacuation, lowers cutting forces, and minimizes vibration for stable, productive milling and longer tool life.
• 4-Flute Design with Coating: Balances rigidity and chip clearance while the coating improves wear resistance and heat tolerance to extend tool life in demanding materials.

This combination of geometry and coating supports consistent, reliable performance across repeated passes, enabling smoother surfaces, fewer tool changes, and better overall efficiency in your milling operations.
