At a Glance
Wide material range
The step drill bit set is suitable for drilling in steel, aluminium, cast iron, bronze, brass and plastic with diameters ranging from 5 to 30 mm.
Secure shank fixing
The 3-flat shank prevents the drill bit from slipping in the chuck and ensures stable power transmission during use.
Precise centring
The tools enable direct drilling without prior pilot drilling or centre punching, which reduces slipping on round surfaces.
