Made of high-quality HSS steel for greater stability and durability The drill bit size is 10-45 mm With titanium coating for additional surface hardness. Suitable for various materials Compatible with all standard drills Features: A step drill bit is a valuable aid for achieving clean and precise drilling. The tool is very popular due to its versatile use in a wide range of applications: in the automotive, sanitary, heating technology, or mechanical engineering sectors. Its production from solid, high-quality HSS steel makes it suitable for processing materials such as stainless steel, structural steel, and plastic. The titanium coating prevents the formation of friction and heat and significantly increases the surface hardness. The drill bit also features a deburring area for deburring the rear cutting surface. The three-sided handle also prevents the chuck from slipping. Thanks to the spiral cutting shape, drilling burr-free holes with a diameter of 10-45 mm will no longer be a
