ITC Carbide End Mill Corner Radius 5031 - 5 Flute Variable Helix Roll Relief Harmonic Fluting Radius + Coating - Steels & Exotics - 12mm x R2.5

Introducing the ITC Carbide End Mill Corner Radius 5031, a high-performance cutting tool engineered for steels and exotic materials. With a 12 mm diameter and a 2.5 mm corner radius (R2.5), it delivers precise curved radii on complex parts while maintaining reliable chip control and steady cutting action. Built for professionals who demand consistent results, it helps achieve accurate finishes even in challenging, hard-to-machine alloys.

This end mill combines a 5-flute design with a variable helix, roll relief, harmonic fluting, and a specialized coating to optimize performance under demanding conditions. The geometry and coating work together to reduce cutting forces, improve stability, and extend tool life when machining tough materials and intricate profiles.

• Efficient chip evacuation: Roll relief and harmonic fluting promote clean chip flow, lowering heat and reducing the risk of built-up edges during heavy cuts on steels and exotic materials.
• Stable, precise cuts: The 5-flute layout with a variable helix delivers rigidity and smoothness, minimizing vibration for consistent radii and better surface finish on curved features.
• Durable carbide with specialized coating: Hardened carbide plus a protective coating resist wear in abrasive materials, helping maintain sharpness and extend tool life across demanding jobs.

Used in production or shop environments, this end mill helps you complete complex radii faster, with tighter tolerances and fewer tool changes. It supports reliable performance across hard-to-machine materials, contributing to improved throughput, better part quality, and more predictable machining results.
