Stepped metal drill bits 4pcs 4-32mm

Stepped drill bits are used for drilling circular holes in ferrous and non-ferrous sheets, pipes, and profiles up to a wall thickness of 4mm, for drilling and deburring in one operation. They can also be used for drilling into soft materials, such as wood, plastic, and Plexiglas. The conical drill is intended for smooth and burr-free drilling and chamfering of holes without deforming the sheet. The drills can be re-sharpened.
