ITC Carbide End Mill Corner Radius 5031 - 5 Flute Variable Helix Roll Relief Harmonic Fluting Radius + Coating - Steels & Exotics - 10mm x R2

Introducing the Carbide End Mill Corner Radius 5031, a purpose-built cutting tool engineered for high-performance machining of steels and exotic materials. With a 10 mm diameter and a 2 mm corner radius (R2), this end mill combines a 5-flute design with a variable helix, roll relief, harmonic fluting, and a specialized coating to deliver efficient chip evacuation, gentler cutting forces, and longer tool life.

Designed for professionals and serious enthusiasts tackling curved surfaces and hard alloys, this tool maintains stable cuts, reduces heat buildup, and produces consistent radii and surface finishes across multiple passes. Its durable carbide construction and tuned geometry help you keep production running smoothly, even on demanding jobs.

• 5-Flute Variable Helix with Roll Relief: Minimizes vibration and chatter, enhances chip evacuation, and delivers smoother, more precise cuts on tough materials and curved geometries.
• Harmonic Fluting with Corner Radius: Optimized edge engagement around the R2 radius for consistent radii and surface finishes, while reducing cutting forces and rubbing.
• Coating Optimized for Steels & Exotics: Provides superior wear resistance and edge protection, extending tool life in demanding materials and helping maintain sharpness between changes.

With its proven geometry and durable coating, the 5031 corner-radius end mill helps you achieve reliable, repeatable results faster. Expect fewer passes to reach depth, cleaner corners, and longer tool life in hard steels and exotic alloys. This translates to less downtime, higher throughput, and confidence that your parts meet tight tolerances on curved features.
