ITC Carbide End Mill Corner Radius 4081 - 4 Flute 38° Helix With Roll Relief, Harmonic Fluting, Radius & Coating - Steels & Exotics - 20mm x R0.75

Developed for steels and exotic materials, the ITC Carbide End Mill Corner Radius 4081 is a high-performance cutting tool designed for reliable, precise material removal. With a 20 mm diameter, a 4-flute configuration, and a R0.75 corner radius, this end mill delivers accurate profiles and durable edges in demanding geometries. The 38° helix, roll relief, harmonic fluting, and specialized coating work together to improve chip evacuation, reduce cutting forces, and extend tool life in tough applications.

• Corner Radius for Complex Profiles: The R0.75 corner radius enables precise inside corners and smooth contours, reducing finishing steps and improving part quality in steels and exotic materials.
• 38° Helix with Roll Relief: A steep, stable helix paired with roll relief lowers cutting forces and enhances chip evacuation for cleaner cuts and longer tool life.
• Harmonic Fluting with Durable Coating: Harmonic fluting minimizes vibration for stable cuts while the specialized coating resists wear, extending life in hard alloys and exotic metals.

This combination supports faster, more reliable machining with fewer tool changes and less rework. By delivering consistent finishes and predictable performance across challenging materials, it helps professional shops and serious hobbyists improve productivity and achieve higher-quality results.
