ITC Carbide End Mill Corner Radius 4081 - 4 Flute 38° Helix With Roll Relief, Harmonic Fluting, Radius & Coating - Steels & Exotics - 20mm x R3

Introducing the ITC Carbide End Mill Corner Radius 4081, a high-performance cutting tool designed for steels and exotic materials. This 20 mm diameter end mill features a 3 mm corner radius, a 4-flute design, a 38° helix, roll relief, harmonic fluting, and a specialized coating to deliver efficient chip evacuation, stable cutting, and extended tool life in demanding geometries.

• 3 mm Corner Radius for durable edges: The precise corner radius strengthens cutting corners, reduces chipping, and supports smoother finishes on hard steels and exotic alloys, helping parts maintain accurate geometry over long runs.
• 38° Helix with Roll Relief and Harmonic Fluting: Optimized chip flow and cutting stability minimize vibration and tool wear, delivering consistent performance even in challenging materials and intricate pocketing paths.
• Specialized Coating for extended life: The coating lowers wear and improves heat resistance, enabling longer tool life, fewer tool changes, and reliable results across mixed-material jobs.

By combining a robust geometry with advanced flute design and protective coating, the ITC Corner Radius 4081 supports faster material removal, cleaner surfaces, and predictable results. It’s a trusted choice for professionals who need reliable performance on steels and exotic materials, reducing downtime and improving throughput in demanding machining applications.
