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-K6UF
Our new carbide grade for reaming applications. Offering a relatively low cobalt content of 6 %, this grade has been developed specifically with reaming applications in mind that demand both superior hardness and resistance to wear. K6UF is also well-suited for drilling applications with composite materials and for deep-hole drilling.
