High Performance Finishing End Mill Cutting Tools 4 Flutes Long Service
KTC Tungsten Carbide High Speed High Hardness End Mills
Flat end mills are constructed of M7 high speed steel, solid carbide, or M42 or PM30 cobalt. Carbide and cobalt mills are considerably harder, more rigid and resistant to heat generated during the milling process. They can also be run at faster speeds than high speed steel mills. Square end mills can also be coated with a variety of ceramic coatings that reduce wear and friction which results in increased speed and tool life.
Specifications
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.
