  • GENERAL METAL MACHINING APPLICATION (UP TO HRC58)：Designed for general machining of mild steel, alloy steel, and cast iron with hardness up to HRC58, suitable for common CNC milling and workshop operations
  • CM124 MICROGRAIN CARBIDE WITH 12% COBALT：Manufactured from ultra-fine grain carbide rods (CM124) containing 12% cobalt, providing an excellent balance of toughness, wear resistance, and cutting stability
  • 4 FLUTE HIGH-SPEED SOLID CARBIDE BALL NOSE / CORNER RADIUS DESIGN：Features a high-speed solid carbide 4-flute ball nose (corner radius R1) structure, optimized for finishing, contouring, and 3D surface machining of steel and cast iron. The multi-flute design enhances tool rigidity, enables stable high-speed cutting, improves surface finish, and offers greater edge durability compared to 2-flute end mills in metal machining applications
  • 35° HIGH HELIX & OPTIMISED EDGE GEOMETRY：The 35-degree large helix angle ensures cutting sharpness, while the specially designed front and back angles enhance edge strength and wear resistance
  • NOMINAL FLUTE LENGTH WITH REINFORCED END DESIGN：The listed flute length refers to the nominal design length. Due to reinforced end geometry for edge strength and tool life, the effective cutting length near the tool end may be slightly shorter, which is normal for carbide end mills
  • NANO COATING FOR HEAT & WEAR RESISTANCE：Advanced nano coating reduces friction and heat buildup during machining, improving tool life and maintaining consistent performance in steel and cast iron cutting
