This wolfcraft step drill bit is designed for precise drilling in stainless steel, sheet steel, nonferrous metals and plastic. This drill bit has a unique flute design, which ensures that it drills perfectly round holes into sheet metal. A fluted shank also prevents the drill bit from slipping into the chuck. It also has a self-centring point, which ensures that it will not walk and which eliminates the need for centre punching. The drill bit is made of high-speed steel. Delivery includes one step drill bit with a gradual diameter: 4/6/8/10/12/14/16/18/20 mm.
