Conical / step drills

Perfect tool for handling sheet material. They are used in such industries as electrical engineering, plumbing and heating devices, car service, aviation production and for the manufacture of panel equipment. The tool is suitable for working on common industrial materials such as non-ferrous metals, tool steel, plastic, duroplast, as well as sheet steel with a thickness of not more than 4.0 mm. Squirrels work without prior centering. And thanks to their hollowing out of a solid solid form with the help of cubic boron nitride - CBN, the cutting edges of the drills are more robust and sharp.
