ITC Carbide End Mill Corner Radius 5031 - 5 Flute Variable Helix Roll Relief Harmonic Fluting Radius + Coating - Steels & Exotics - 12mm x R0.25

The Carbide End Mill Corner Radius 5031 is a 12 mm diameter carbide cutting tool designed for precision machining of steels and exotic materials. It features a 0.25 mm corner radius, a 5-flute design with variable helix, roll relief, harmonic fluting, and a specialized coating to boost durability and performance.

Designed for professionals and enthusiasts who need reliable, repeatable results on curved profiles and demanding materials, it delivers efficient chip evacuation, reduced cutting forces, and extended tool life—helping you achieve clean corners and smooth finishes with confidence.

• Variable Helix Design: The variable helix reduces vibration and chatter, providing smoother cutting and longer tool life when working with steels and exotic materials.
• Roll Relief & Harmonic Fluting: Roll relief lowers contact pressure on the flute, while harmonic flute geometry enhances stability and chip evacuation for clean cuts and reduced burrs.
• Corner Radius Geometry with Durable Coating: The 0.25 mm corner radius enables precise fillets on curved profiles, and the specialized coating improves heat resistance and wear performance for demanding materials.

In use, this end mill delivers consistent, high-quality finishes on challenging workpieces, lowers downtime through extended tool life, and supports accurate depth control across complex geometries. Its robust carbide core and coating are trusted for reliability in production environments and precise manual machining alike.
