GMF53/GMF57 series CHAMFER EDGE PREP end mills are available from 3-20mm diameter with a Weldon shank. The V7 plus range from YG-1 offer the highest metal removal rates and silent machining of steels, stainless steels, heat resistant super alloys such as inconel & cast iron. The special multiple helix design eliminates vibration when employing large cuts and high feed rates. The results are exceptional tool life, excellent surface finish and the shortest cycle times. For the best results use in a hydraulic chuck or high-performance tool holder with excellent clamping torque.

  • Y1200 coated ultrafine micrograin carbide
  • HPC (High performance cutting)
  • Multiple helix geometries and unequal flute spacing enable higher feed rates and larger cut depths
  • Helix & unequal flute spacing reduces vibration
  • High heat resistance of Y1200 coating ensures exceptional tool life in stainless steel, titanium and HRSA machining
  • Chamfer corner protection to prevent against tool chipping
