The Alpha Onsite+ 6-30mm step tip step drill is a single bit that cuts a range of hole sizes from 6mm up to 30mm. Its patented step tip starts the hole without pre-drilling, so you can go straight in and step up to the size you need, producing clean, burr-free holes.
A handy bit for sparkies, fabricators and DIYers drilling sheet steel, plastic and similar materials. Because one step drill covers many sizes, it saves swapping bits on the job, and the step-tip start means no separate pilot hole before you cut.
