Step Drill Bits 4-32mm 3pc HSS Titanium Coated for Metal

A 3-piece step drill bits set for drilling a range of hole sizes in thin metal without changing between multiple standard drill bits. Made from HSS and finished with a titanium coating, the set covers sizes from 4mm up to 32mm for common workshop and fitting jobs.

Used for sheet metal work, electrical fitting, garage repairs and general workshop use, these stepped hole cutters are handy when you need to enlarge existing holes or drill neat new ones in thin materials. They suit trade work, vehicle maintenance and DIY repairs where different hole sizes are needed for brackets, panels, trunking, light fabrication and similar jobs.

The set includes three step drill bits in overlapping size ranges: 4-12mm, 4-20mm and 4-32mm, giving good coverage for small to larger holes in one pack. The stepped design helps with controlled sizing as you work up through the bit, which is useful when accuracy matters on thinner metal sections. A supplied pouch keeps the bits together between jobs and helps keep accessories organised in the toolbox or van. With three commonly useful ranges in one set, it helps avoid constant bit swapping during regular drilling work.
