ITC Carbide End Mill Corner Radius 5031 - 5 Flute Variable Helix Roll Relief Harmonic Fluting Radius + Coating - Steels & Exotics - 8mm x R2.5

The ITC Carbide End Mill Corner Radius 5031 is a high‑performance milling tool designed for steels and exotic materials. With an 8 mm diameter and a 2.5 mm corner radius, it creates precise, rounded inner corners on curved profiles while delivering efficient material removal and consistent hole and pocket finishes.

Built for professionals who demand dependable, repeatable results, this 5‑flute end mill features a variable helix, roll relief, harmonic fluting, and a specialized coating. The advanced geometry supports stable cuts, efficient chip evacuation, and extended tool life when machining tough alloys and exotic workpieces.

• 5‑Flute, Variable Helix for Stable Cutting: Enhances rigidity and reduces vibration, enabling clean, accurate finishes on radii and challenging materials.
• Roll Relief & Harmonic Fluting for Lower Cutting Forces: Dampens chatter and lowers cutting forces for smoother operation and improved surface quality.
• R2.5 Corner Radius with Durable Coating: Delivers precise corner geometry on 8 mm parts while the coating improves wear resistance and longevity in steels and exotics.

This end mill helps you complete curved profiles and pockets with confidence, delivering consistent results from start to finish. The combination of optimized flute geometry, vibration control, and wear‑resistant coating translates to fewer tool changes, improved productivity, and reliable performance across demanding milling applications.
