ITC Carbide End Mill Corner Radius 4081 - 4 Flute 38° Helix With Roll Relief, Harmonic Fluting, Radius & Coating - Steels & Exotics - 3mm x R1

The ITC Carbide End Mill Corner Radius 4081 is a precision cutting tool designed for demanding steels and exotic materials. With a 3 mm diameter and a 1 mm corner radius (R1), this end mill delivers accurate, clean corners and smooth profiles for complex geometries commonly found in engineering and manufacturing applications.

Engineered for reliability, it combines a 4-flute geometry with a 38° helix, roll relief, harmonic fluting, a defined radius, and a specialized coating. This advanced configuration promotes efficient chip evacuation, lowers cutting forces, stabilizes the cut, and extends tool life even when working with tough materials and intricate contours.

• Corner Radius for Precise, Smooth Corners: The 1 mm corner radius enables accurate contouring and reduces edge chipping, helping you achieve high-precision finishes on steels and exotic alloys.
• 38° Helix with Roll Relief and Harmonic Fluting: This geometry reduces vibration and cutting forces while improving chip evacuation, delivering steadier cuts and consistent surface quality.
• Durable Carbide with Specialized Coating: The hardened coating enhances heat resistance and wear protection, helping the tool maintain sharpness and extend life in demanding materials.

This end mill supports faster, more reliable machining by delivering precise corners, stable performance, and longer tool life. It helps you finish complex parts with cleaner edges, fewer passes, and less downtime—boosting productivity across a wide range of professional and DIY applications.
