M35 Cobalt-Coated Step Drill

Product Features：

The M35 cobalt step drill (HSS Co) is a step drill with very high hardness, mainly used for drilling high-hardness steel plates, such as stainless steel plates and quenched steel plates, meeting tasks that many customers cannot accomplish with ordinary HSS4241 step drills. When drilling stainless steel, a hand drill or a bench drill can be used. A hand drill can drill plates up to 1mm thick, and a bench drill can drill plates 2-3mm thick.
