Karnasch premium step drills & tube and sheet drills
One of the most comprehensive stock ranges of step drills and tube and sheet drills
Karnasch step drills are designed to produce perfect circular and simultaneously deburred holes in sheets up to 4 mm. The transition from one step to the other is used for chamfering or deburring the drill hole.
The Karnasch tube and sheet drills are designed for drilling thin sheets up to 4 mm. They are ideal for enlarging existing holes, drilling oblique holes and creating interlocking holes. The peeling cut produces almost burr-free holes on both sides.
