Product Description
The GPP 4 Flute Corner Radius End Mill is a high-performance solid carbide end mill engineered for precise, productive milling. Manufactured from premium ultra-fine grain tungsten carbide, it combines high hardness with the toughness needed for consistent, chatter-free cutting and a superior surface finish. It is optimized for machining hardened steel.
Precision edge preparation and a carefully engineered helix angle reduce cutting forces and improve chip evacuation, allowing higher feed rates without sacrificing accuracy. An advanced PVD coating lowers friction and dissipates heat, extending tool life even in continuous production.
Key Features
- Sub-micron grain tungsten carbide substrate for an ideal balance of hardness and toughness
- Precision-ground cutting edges hold tight diametral tolerances for accurate, repeatable results
- Optimized helix angle evacuates chips cleanly and reduces cutting forces
- Advanced nano-coating lowers friction and resists heat for extended tool life
Applications
Ideal for CNC milling, slotting, profiling, contouring and finishing. MSU Tools also manufactures custom geometries, coatings and dimensions to suit your specific material and application — contact our engineering team to discuss your requirements.
