Whether in the electrical and automotive industries, in plumbing and heating technology or mechanical engineering, this step drill is the perfect tool for clean and precise drilling. Made from high-quality, stable HSS steel, it can be used for a wide range of different materials such as wood, plastic and metal. The drill bit has a titanium coating, which prevents the build-up of friction and heat and at the same time ensures a higher surface hardness. Thanks to the twisted cutting geometry, you can easily make holes with a diameter of 4-32 mm without pre-drilling.
