HSS Step Cone Drill Bit Titanium 4-20mm Pagoda Drill Deburring

No matter if in the electrical and automotive industry, in plumbing, heating or mechanical engineering: this step drill bit is the perfect tool for clean and precise drilling. Made of durable, high-quality high-speed steel, it allows for a flexible processing of a wide variety of materials, such as stainless steel, mild steel and plastic.The drill bit has a titanium coating that prevents the formation of friction and heat while providing increased surface hardness. In addition, the bit is equipped with a deburring zone for deburring the rear cutting surface as well as a three-surface shank that prevents the drill chuck from slipping. Thanks to the helical cutting geometry, you can easily make burr-free holes with a diameter of 4-20 mm without pre-drilling.
