ITC Carbide End Mill Corner Radius 5031 - 5 Flute Variable Helix Roll Relief Harmonic Fluting Radius + Coating - Steels & Exotics - 4mm x R0.25

The Carbide End Mill Corner Radius 5031 is a 4 mm diameter, 5-flute carbide cutter designed for steel and exotic material machining. It combines a precise R0.25 corner radius with a specialized coating, along with a variable-helix, roll-relief, and harmonic-fluting geometry to deliver efficient chip evacuation, lower cutting forces, and steadier cuts on curved features.

• Variable Helix for smoother cuts: Minimizes chatter and vibration across a range of materials, helping you achieve consistent finishes and easier tool control during demanding milling operations.
• Roll Relief + Harmonic Fluting for stability and finish: Designed to reduce cutting loads and promote uniform chip formation, which translates to better surface quality and longer tool life in tough steels and exotic alloys.
• Precise Corner Radius with durable coating: The 0.25 mm radius enables accurate radii on curved profiles while the coating enhances wear resistance and reliability in challenging machining environments.

This end mill is built for professionals who require dependable performance, precise radii, and extended tool life in difficult materials. Its combination of geometry and coating supports efficient machining workflows, reduced rework, and consistent results across multiple passes and profiles.
