ITC Carbide End Mill Corner Radius 4081 - 4 Flute 38° Helix With Roll Relief, Harmonic Fluting, Radius & Coating - Steels & Exotics - 12mm x R3

The ITC Carbide End Mill Corner Radius 4081 is a high-performance cutting tool designed for professionals who machine steels and exotic materials. It features a 12 mm cutting diameter with a corner radius of R3, a 4-flute design, a 38° helix, roll relief, harmonic fluting, and a specialized coating to handle complex geometries with confidence. This end mill is built to improve chip evacuation, reduce cutting forces, and deliver stable cuts under demanding conditions, helping you achieve consistent finishes and longer tool life even on tough alloys.

• R3 Corner Radius for Precise Pockets: Enables clean, accurate radii and reduces stress concentration at corners, improving part fit and minimizing finishing work.
• 38° Helix with Roll Relief and Harmonic Fluting: Enhances chip flow and reduces vibration for smoother cuts, extending tool life and delivering steadier finishes on hard materials.
• Coated Carbide with 4 Flutes: Combines wear‑resistant coating and robust geometry to deliver reliable performance in steels and exotic alloys, reducing downtime and tool changes.

Designed to support efficient workflows, this end mill helps you complete pockets, contours, and radii faster with fewer passes and more consistent results. Its durable construction and optimized geometry reduce downtime, improve surface finish, and provide predictable performance across challenging jobs, making it a dependable addition to any shop floor.
