ITC Carbide End Mill Corner Radius 4081 - 4 Flute 38° Helix With Roll Relief, Harmonic Fluting, Radius & Coating - Steels & Exotics - 16mm x R4

Meet the ITC Carbide End Mill Corner Radius 4081—a precision cutting tool engineered for demanding steels and exotic alloys. The 16 mm diameter with a 4-flute design features a 38° helix, roll relief, harmonic fluting, an R4 corner radius, and a specialized coating to maintain accuracy and control across complex profiles.

This combination delivers efficient chip evacuation, lower cutting forces, and extended tool life, making it a reliable choice for professionals and shops tackling challenging materials and intricate geometries.

• Efficient chip evacuation and heat management: The 38° helix, harmonic fluting, and R4 corner radius work together to channel chips away smoothly while distributing heat, helping maintain precision and extending tool life.
• Stable performance on steels and exotic materials: Designed for tough alloys, this end mill maintains sharpness and consistent finishes even in challenging metals and complex geometries.
• Durable carbide with specialized coating: Premium carbide paired with a protective coating reduces wear, resists built-up edge, and delivers reliable cuts over more cycles.

In practical use, this end mill helps you achieve precise profiles and clean finishes with fewer passes, reducing cycle times and downtime. The R4 corner radius produces smooth transitions and strong part contours, while the optimized flute geometry and coating contribute to longer tool life and predictable results across demanding applications.
