ITC Carbide End Mill Corner Radius 5031 - 5 Flute Variable Helix Roll Relief Harmonic Fluting Radius + Coating - Steels & Exotics - 16mm x R2.5

The ITC Carbide End Mill Corner Radius 5031 is a high-performance cutting tool designed for precision work in steels and exotic materials. Its 5-flute design combines a variable helix, roll relief, and harmonic fluting with a defined corner radius and a specialized coating to improve chip evacuation, reduce cutting forces, and extend tool life.

With a 16 mm diameter and a corner radius of 2.5 mm (R2.5), this end mill is ready for curved features and demanding profiles, delivering consistent radii and smooth surface finishes across tough materials.

• 5‑Flute Variable Helix with Roll Relief: Balances cutting forces and minimizes vibration for stable entry and cleaner finishes when machining steels and exotic alloys.
• Corner Radius R2.5 for Curved Features: Maintains precise radii on curved geometry, reducing edge chipping and preserving part accuracy.
• Specialized Coating for Tough Materials: Enhances wear resistance and heat management, delivering longer tool life and reliable performance in challenging workpieces.

This combination of geometry and coating translates into faster, more predictable machining. You’ll experience less downtime from dulling or breakage, fewer tool changes, and consistent tolerances on curved surfaces. The ITC 5031 end mill is designed to deliver dependable results across steels and exotic materials, helping you finish jobs on time and with repeatable quality, whether you’re prototyping, producing, or refurbishing components.
