Step drill bit set 4–32 mm

Set with three HSS step drill bits for drilling and enlarging holes in thin sheet metal, metal, plastic and other suitable materials. The set is practical for workshops, motorsport, tuning and custom builds where clean and precise holes in different sizes are often needed.

A step drill bit, also called a cone drill bit, makes it possible to drill several hole sizes with the same drill bit. The stepped design makes it easier to enlarge existing holes in a controlled way and achieve a clean edge without constantly changing drill bits.

The set covers sizes from 4 millimetres to 32 millimetres and is therefore suitable for mounting grommets, switches, cable routing, fittings, brackets and other components. The hex shank provides a good grip in the drill chuck and helps reduce the risk of the drill bit slipping during use.
