ITC Carbide End Mill Corner Radius 5031 - 5 Flute Variable Helix Roll Relief Harmonic Fluting Radius + Coating - Steels & Exotics - 3mm x R0.5

The Carbide End Mill Corner Radius 5031 is a precision cutting tool designed for high-performance milling in steels and exotic materials. With a 3 mm diameter and a 0.5 mm corner radius, it delivers accurate internal radii and consistent geometry across curved features. The 5-flute design combined with variable helix, roll relief, harmonic fluting, and a specialized coating works together to optimize chip evacuation, reduce cutting forces, and extend tool life.

Designed for professionals who demand reliability and precision, this end mill is ideal for engineers, machinists, and shops tackling tough alloys and complex geometries. Expect smoother finishes, lower vibration, and dependable performance when machining curved pockets or challenging materials.

• 5‑Flute Variable Helix for Smooth, Efficient Cutting: Balances rigidity and material removal while reducing chatter and improving chip clearance for clean, accurate cuts in steels and exotic materials.
• Roll Relief & Harmonic Fluting for Stability: Minimizes edge rubbing and cutting forces; harmonic flute geometry promotes steady engagement, enhancing surface quality and tool life.
• Corner Radius R0.5 with Durable Coating: Enables precise internal radii with strengthened corner integrity; coating delivers wear resistance and better heat tolerance for longer tool life in demanding applications.

This end mill helps you maintain tight tolerances on curved features, reduces downtime from wear-related replacements, and supports faster, more predictable production runs. By combining advanced geometry with coating protection, it delivers consistent performance from the first cut to the last, making it a dependable choice for challenging milling tasks.
