Grade GC-K40UF

Our most universal carbide grade for an exceptionally wide range of applications K40UF is made of ultrafine tungsten carbide with a grain size of 0.7 µm. In combination with a cobalt content of 10 %, this allows for both superior hardness and toughness to be attained. The ultrafine grain carbide grade K40UF is particularly suitable for milling and, on account of its cutting-edge stability, has become our standard grade for high-performance drilling. Well-suited for drilling or milling applications with high-temperature alloys, stainless steels, gray cast iron, titanium alloys, and glass-fiber reinforced plastics.

Grade GC-K44UF

This grade offers a cobalt content of 12 % and a grain size of 0.5 µm, ensuring extremely high toughness while at the same time maintaining substantial hardness. Next to drilling and tapping, this grade lends itself well to milling applications with titanium alloys, high-temperature alloys, gray cast iron, stainless and hardened steels, glass-fiber reinforced plastics, and composite materials.
