Stepped drill bits are used for drilling circular holes in iron and non-iron sheets, tubes, and profiles up to a wall thickness of 4mm, for enlarging and deburring in one working operation. They can also be used for drilling into soft materials, such as wood, plastic, and plexiglass. The steel drill bit is designed for smooth and burr-free drilling and enlarging of holes without deformation of the sheet. The drill bits can be re-sharpened.
