Step Drill Bit Set 3pc HSS Titanium Coated Hex Shank

A 3-piece step drill bit set for drilling and widening holes in thin metal and plastic. Made from HSS with a titanium nitride coating, these bits use a 1/4in hex shank and give you a compact option for sheet material, panel work and general fitting jobs.

Used for enlarging existing holes or creating new ones in light-gauge materials, this step bit set is handy for garage work, workshop use, electrical fitting, automotive jobs and DIY repairs. It suits anyone working on thin sheet metal, plastic panels, trunking, covers or enclosures where a stepped bit can help produce the size needed without reaching for several separate drill bits. For regular maintenance and installation work, it is a practical choice when different hole sizes come up on the same job.

The set includes three size ranges: 3-12mm, 4-12mm and 6-20mm, which helps cover a useful spread of common hole sizes. Each bit has a titanium nitride coated HSS construction, while the 1/4in hex shank gives a straightforward fit for compatible drills and bit holders. A nylon storage bag is included, making it easier to keep the bits together between jobs and helping keep accessories organised in the toolbox or van. The stepped format is also useful when controlled hole enlargement is needed on thinner materials.
