Grade GC-K55SF

Our newly-developed premium carbide grade for high-performance applications has set the benchmark for carbides. K55SF is made of superfine tungsten carbide with grain sizes between 0.2 and 0.5 µm, significantly surpassing the hardness of our previous grades. This super-fine grain carbide grade features high cutting-edge stability while maintaining high wear resistance and considerable toughness. The application scope spans the usage with highly wear-resistant materials, such as stainless and hardened steels, graphite, high-strength aluminium alloys, as well as abrasively acting composite materials, e.g. Kevlar® and GFRP. Taking advantage of this material’s full potential and superior performance means using it in demanding applications which require feed rates or cutting speeds that are significantly higher than those supported by conventional carbide materials.
