Made from high-quality HSS steel for stability and durability Drill size is 10-45 mm With titanium coating for additional surface hardness Suitable for various materials Compatible with all common drills Features: A step drill is a valuable tool for successful, clean and precise drilling. The tool is very popular due to its versatile use in a wide variety of applications: in the automotive, sanitary, heating technology or mechanical engineering sectors. Because it is made from stable and high-quality HSS steel, it is suitable for machining materials such as stainless steel, structural steel and plastic. The titanium coating prevents the formation of friction and heat on the one hand and ensures that the hardness of the surface is significantly increased on the other. The drill also has a deburring zone that is used to deburr the rear cutting surface. In addition, the three-sided sleeve has the advantage of preventing the chuck from slipping. Thanks to the spiral cutting shape, making
