ITC Carbide End Mill Corner Radius 4081 - 4 Flute 38° Helix With Roll Relief, Harmonic Fluting, Radius & Coating - Steels & Exotics - 8mm x R0.25

The ITC Carbide End Mill Corner Radius 4081 is a high-performance cutting tool engineered for machining steels and exotic materials. Built as a 4-flute end mill with a 38° helix, roll relief, harmonic fluting, a precise corner radius, and a specialized coating, it combines advanced geometry with durable construction to deliver efficient chip evacuation, reduced cutting forces, and stable, reliable performance. Sized at 8 mm in diameter with a 0.25 mm corner radius (R0.25), it’s ideal for complex corners and deep pockets where precision matters.

• 4-flute rigidity and efficient material removal: Four cutting edges provide balanced chip load and enhanced rigidity, enabling confident feeds in steels and exotic materials for faster, more consistent material removal.
• 38° helix with roll relief and harmonic fluting: Optimized flute geometry reduces cutting forces, minimizes vibration, and promotes smooth entry and exit, improving surface finish and tool life on tough alloys.
• Corner radius and coating for durability: The precise R0.25 corner radius maintains geometric accuracy while the protective coating and carbide construction resist wear in demanding applications, extending usable life between changes.

This end mill is designed to streamline your workflow: you get reliable corners, repeatable finishes, and longer tool life in demanding materials. The combination of geometry, coating, and build quality helps reduce downtime from tool wear and rework, delivering consistent results project after project and making it a dependable choice for professional shops and serious hobbyists working on challenging steels and exotic materials.
