ITC Carbide End Mill Corner Radius 4081 - 4 Flute 38° Helix With Roll Relief, Harmonic Fluting, Radius & Coating - Steels & Exotics - 8mm x R0.5

The ITC Carbide End Mill Corner Radius 4081 is a high-performance cutting tool designed for precise corner radii in steels and exotic materials. With an 8 mm diameter and a 0.5 mm radius, this 4-flute end mill features a 38° helix, roll relief, harmonic fluting, and a specialized coating to deliver reliable, consistent cuts on complex geometries.

• Corner radius for precise, repeatable edges: Achieves a consistent R0.5 corner radius on every pass, reducing post-machining finishing and ensuring tight tolerances.
• 38° helix with roll relief and harmonic fluting: Delivers smoother cutting action, improved chip evacuation, and reduced cutting forces for steadier operations and longer tool life.
• Coated carbide for steels and exotic materials: Provides enhanced wear resistance and heat tolerance, maintaining sharpness and extending tool life in challenging alloys.

This tool helps you complete parts faster with tighter tolerances, fewer secondary operations, and longer intervals between tool changes. The precise R0.5 corner radius supports clean, accurate corners, while the flute design, helix angle, and coating work together to deliver stable cutting, better surface finishes, and reliable performance in demanding materials.
