ITC Carbide End Mill Corner Radius 4081 - 4 Flute 38° Helix With Roll Relief, Harmonic Fluting, Radius & Coating - Steels & Exotics - 5mm x R1

The ITC Carbide End Mill Corner Radius 4081 is a 5 mm diameter carbide end mill with a 1 mm corner radius, engineered for high-precision machining in steels and exotic materials. It features a 4‑flute design, a 38° helix, roll relief, harmonic fluting, a defined radius, and a specialized coating to support clean radii, steady cutting, and longer tool life.

Ideal for professionals and shops that routinely work with challenging geometries—from tight radii and fillets to complex pockets—this end mill delivers reliable performance, efficient chip evacuation, and consistent results across demanding applications.

• Corner Radius for Smooth Fillets: Enables clean, precise radii and durable edges on steels and exotic alloys, reducing post-machining finishing and improving part accuracy.
• 38° Helix with Roll Relief & Harmonic Fluting: Promotes smooth cutting and efficient chip flow while minimizing vibration and cutting forces for stable performance in hard materials.
• Specialized Coating for Extended Tool Life: Enhances wear resistance and heat tolerance, helping the tool maintain sharpness and deliver repeatable results over more cycles.

This end mill is designed to streamline your workflow: achieve accurate radii in a single setup, reduce downtime from tool changes, and maintain consistent finishes across production runs and job-site projects in steel and exotic materials.
