ITC Carbide End Mill Corner Radius 4081 - 4 Flute 38° Helix With Roll Relief, Harmonic Fluting, Radius & Coating - Steels & Exotics - 20mm x R1

Introducing the ITC Carbide End Mill Corner Radius 4081—engineered for precision machining in steels and exotic materials. This 4-flute carbide end mill features a 38° helix, roll relief, harmonic fluting, a defined corner radius (R1), and a specialized coating. With a 20 mm cutting diameter and a 1.0 mm corner radius, it delivers efficient chip evacuation, stable cutting, and extended tool life on demanding geometries.

• Optimized chip evacuation and cooling: The combination of a 4-flute design, harmonic fluting, and roll relief promotes smooth chip flow and reduces heat buildup, helping maintain consistent performance during tough cuts.
• Stable, precision cuts in hard materials: A 38° helix paired with roll relief minimizes cutting forces and chatter, yielding clean finishes and reliable results when machining steels and exotic alloys.
• Durable coating and reliable geometry: A wear‑resistant coating plus a geometry that preserves the corner radius (R1) under demanding operations supports longer tool life and repeatable accuracy across multiple jobs.

This end mill is designed to improve your workflow by delivering predictable feeds and finishes, reducing downtime from tool wear, and enabling you to tackle complex parts with confidence. Whether pocketing, profiling, or finishing tight radii, the ITC Corner Radius 4081 helps you achieve consistent results and higher throughput.
