ITC Carbide End Mill Corner Radius 6021-R - Multi-flute 52° Helix With Roll Relief, Coating & Radius - Steels & Exotics - 12mm x R0.25

Introducing the Carbide End Mill Corner Radius 6021-R, designed for demanding machining in steels and exotic materials. This 12 mm diameter tool features a precise 0.25 mm corner radius (R0.25), a multi-flute design with a 52° helix, roll relief, and a specialized coating to optimize cutting performance and durability.

These elements work together to provide efficient chip evacuation, lower cutting forces, and enhanced cutting stability—helping you achieve reliable results even on challenging materials and curved features.

• 52° Helix with Multi-Flute Geometry: Promotes smooth entry and aggressive material removal while maintaining stability, reducing chatter and improving finish on hard steels and exotic alloys.
• Roll Relief and Special Coating: Minimizes rubbing and heat buildup, extending tool life and enabling longer runs between changes in high-demand applications.
• Precise R0.25 Corner Radius: Delivers accurate curved profiles and consistent surface finish on complex geometries without compromising strength or tool durability.

Whether you’re profiling tight radii, finishing curved pockets, or tackling tough material assemblies, the 6021-R delivers dependable, repeatable performance in a single setup. Its carbide construction and feature set are tailored to meet professional expectations for precision, reliability, and productivity in steel and exotic-material machining.
