ITC Carbide End Mill Corner Radius 5031 - 5 Flute Variable Helix Roll Relief Harmonic Fluting Radius + Coating - Steels & Exotics - 8mm x R0.25

Meet the ITC Carbide End Mill Corner Radius 5031 — a high-performance cutting tool designed for steels and exotic materials. This 8 mm diameter end mill features a corner radius of 0.25 mm (R0.25), 5 flutes, and advanced geometry including variable helix, roll relief, and harmonic fluting, all paired with a durable coating. It’s built for professionals who need reliable performance when machining curved profiles and tough materials.

With its optimized geometry and coating, the 5031 maintains steady cutting forces, promotes smooth chip evacuation, and delivers consistent finishes on challenging parts—from precision pockets to intricate radii.

• Efficient chip evacuation and smooth cutting: The combination of variable helix and harmonic fluting reduces built-up edge and clears chips more effectively, delivering steadier cuts and cleaner finishes on steels and exotic materials.
• Durable carbide with wear‑resistant coating: Premium carbide paired with a wear‑resistant coating extends tool life in tough materials, resisting heat and abrasion for more cycles between replacements.
• Optimized geometry for curved profiles: Roll relief and precise corner radius maintain stability and accuracy when profiling and pocketing curved features, reducing chatter and improving surface finish.

Equipped for demanding workshops and production environments, this end mill helps improve throughput by reducing downtime for tool changes, producing precise radii on curved features, and delivering repeatable results across parts. The combination of carbide hardness, coating wear resistance, and harmonic flute design translates to longer life, fewer replacements, and dependable performance in steels and exotic materials.
