Holemaker® Pro-Cut ASP powder steel cutters offer incredible wear resistance & ductility. ASP® steels are produced by powder metallurgy through a 3-step process: gas-atomisation, hot isostatic pressing and post processing operations such as forging, rolling or drawing. Suitable for drilling railway line, stainless-steel & hardened steels, where high wear resistance and lifetime are required. • Incredible wear resistance • Uniform micro-structure • Less susceptible to breakage
