ITC Carbide End Mill Corner Radius 4081 - 4 Flute 38° Helix With Roll Relief, Harmonic Fluting, Radius & Coating - Steels & Exotics - 5mm x R0.5

The ITC Carbide End Mill Corner Radius 4081 is a high-performance cutting tool engineered for precision milling in steels and exotic materials. With a 5 mm diameter and a 0.5 mm corner radius, it delivers accurate radii and clean pocketing while maintaining strong edge life for demanding parts.

Designed for professionals who demand reliability, this end mill combines a 4-flute design with a 38° helix, roll relief, harmonic fluting, and a specialized coating. The result is efficient chip evacuation, lower cutting forces, and stable performance even when cutting hard alloys and complex geometries.

• Corner Radius for Crisp Edges: The R0.5 corner radius enables precise inside and outside radii, reducing the need for secondary finishing and delivering accurate pocketing in steels and exotic materials.
• 38° Helix with Harmonic Fluting: Optimizes chip flow and minimizes vibration, yielding consistent surface finishes and smoother cuts across challenging materials.
• Roll Relief + Coating for Durability: Roll relief lowers cutting forces and wear, while the advanced coating extends tool life and resists built-up edge during tough machining.

This tooling setup helps you complete parts faster with fewer passes, reduce downtime from tool changeovers, and achieve repeatable results in demanding applications. It’s the dependable choice for machinists, engineers, and shops that prioritize precision, durability, and consistent performance in steels and exotic materials.
