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

The ITC Carbide End Mill Corner Radius 5031 is a high-performance carbide end mill designed for steels and exotic materials. It features a 12 mm diameter with a 2 mm corner radius (R2), along with a 5-flute geometry, variable helix, roll relief, harmonic fluting, and a specialized coating to tackle curved surfaces and demanding alloys. This tool is built for precision and reliability in professional machining environments.

Engineers, machinists, and practitioners who work with tough metals will appreciate the balance of cut stability, efficient chip evacuation, and long tool life this end mill provides. Whether you're finishing tight radii, creating curved pockets, or contouring exotic alloys, it delivers consistent results with minimal downtime.

• 5‑Flute Variable Helix design: Promotes smooth cutting and stable tool engagement, improving surface finish and reducing chatter on curved features in steels and exotic materials.
• Roll relief + Harmonic fluting: Optimizes chip flow and minimizes rubbing, delivering cleaner cuts and lower cutting forces for steadier operation and longer tool life.
• Specialized coating for durability: Provides enhanced wear resistance in tough alloys, helping maintain sharpness over more cuts and reducing risk of built-up edge.

With its combination of geometry, relief, and coating, this end mill helps you complete complex parts faster, maintain tight tolerances on curved geometries, and reduce downtime due to tool wear or breakage. It offers reliable performance across steels and exotic materials, making it a dependable choice for job shops, maintenance teams, and machine operators who demand repeatable, high-quality results.
