ITC Carbide End Mill Corner Radius 4081 - 4 Flute 38° Helix With Roll Relief, Harmonic Fluting, Radius & Coating - Steels & Exotics - 5mm x R0.25

The ITC Carbide End Mill Corner Radius 4081 is a precision carbide cutting tool designed for machining steels and exotic materials. It features a 5 mm cutting diameter with a 0.25 mm corner radius, delivering strong corners without sacrificing tool strength. With a 4-flute design, 38° helix, roll relief, harmonic fluting, and a specialized coating, this end mill is built to optimize chip evacuation, lower cutting forces, and extend tool life.

Designed for professionals and serious hobbyists alike, this end mill provides reliable performance on complex geometries and deep pockets. The optimized flute geometry, coating, and corner radius work together to deliver consistent finishes, reduced heat generation, and long-lasting edge retention even when working with challenging materials.

• 4-flute rigidity for demanding cuts: The four-flute design delivers strong rigidity and efficient chip removal, helping maintain accuracy and reduce deflection in steels and exotic materials.
• 38° helix with roll relief and harmonic fluting: Smooth cutting action with reduced vibration, enabling stable feeds, better surface finish, and lower cutting forces.
• Precise 0.25 mm corner radius with specialized coating: Creates clean corners and fillets while the coating enhances wear resistance and heat management for longer tool life.

With the Corner Radius 4081, you gain dependable, repeatable results from cut to finish. The combination of geometry, coating, and radius supports tighter tolerances, faster cycle times, and superior surface quality on tough materials, making it a reliable choice for production environments, workshops, and field applications where precision matters most.
