Product Description

High Performance Ball Nose Bit Tungsten Carbide High Hard Material Processing





  • Suitable for machining on hardened and high-alloy steel, steel casting, chill casting, malleable cast iron, chromium-nickel steel, brass, copper, aluminum with a high percentage of silicon, and abrasive plastic
  • Extra-long-length end mills have longer cutting edges and can make deeper cuts than long-length end mills
  • Four flutes produce a better finish than fewer flutes
  • Carbide can run at higher speeds than high-speed or cobalt steel, resisting wear and high cutting temperatures
  • Ball nose end mills (also called ball end) create contoured surfaces­­­


HG680 high speed and high hardness milling cutter series is made of high-quality European grain tungsten steel material, with bending strength of 4600mpa and grain size of 0.2 μm, which is coated with imported Balzers high-performance composite coating.
