ITC Carbide End Mill Corner Radius 4081 - 4 Flute 38° Helix With Roll Relief, Harmonic Fluting, Radius & Coating - Steels & Exotics - 1.5mm x R0.25

The ITC Carbide End Mill Corner Radius 4081 is a precision carbide milling tool engineered for demanding steel and exotic-material work. With a 1.5 mm diameter and a 0.25 mm corner radius, it combines a 4-flute design, a 38° helix, roll relief, harmonic fluting, and a specialized coating to optimize cutting performance. This setup delivers reliable, efficient cuts even on tough alloys and complex geometries.

Designed for professionals who demand consistent radii, tight tolerances, and smooth finishes, this end mill excels in pockets, profiles, and shoulder operations. Its geometry and coating work together to improve chip evacuation, reduce cutting forces, and extend tool life—helping you achieve repeatable results across batches without constant tool changes.

• Corner Radius R0.25 for Durable, Accurate Corners: The precise 0.25 mm radius strengthens corner integrity, reduces stress concentrations, and promotes longer tool life while delivering consistent radii in tight features.
• 38° Helix with Roll Relief and Harmonic Fluting: This advanced geometry supports faster material removal with minimal vibration, smoother chip flow, and improved cutting stability for clean finishes on hard materials.
• Coated Carbide for Steels & Exotics: The specialized coating paired with a carbide body resists wear in tough alloys, enabling higher feed rates, reduced downtime, and reliable performance in demanding applications.

Shareable confidence comes standard with the ITC 4081: you get a compact, rigid tool that maintains precision across challenging steels and exotic materials, minimizes tool changes, and delivers consistent surface quality. Whether you’re prototyping, batch-manufacturing, or finishing intricate features, this end mill helps streamline setup, improve throughput, and achieve dependable, repeatable results with every cut.
