The high level of hardness and extreme bending strength make this carbide grade particularly suitable for boring electronics boards and other fibre-reinforced plastics as well as milling complex materials with mini-milling cutters made of CKi®09. These complex materials include titanium-carbon sandwich constructions, hardened steel, titanium alloys and stainless steels.
The extremely high wear resistance and the impressive hardness of this carbide are due to the use of super fine grained tungsten carbide powder. The specially adapted sinter-HIP process ensures a high level of toughness while also providing optimum hardness.
