Ultra micro-grain quality carbide standard 2-flute key way and R angle end mill

   
Concentricity⊙≤0.005mm.
◆.Extensively applied and lengthened, It has excellent cutting performance (sharp and perfect blade quality and excellent chip discharge), so it is applicable for extensive field from general machining to special machining.
 ◆.2-flute (flute passing center) 45°high helix (MR11) can be applied in normal finish machining and quench-hard finish machining (machining of HRC40°-60°)
 ◆.VRA201:It can be applied in discontinuous milling of materials with larger impact performance, but due to
its bad wear resistance, it is applied in special machining of materials between high cobalt steel M42 (bad wear resistance) and general tungsten steel (brittle)
