What this step drill does
The Walter Surface Technologies 01W111 is a straight-flute step drill with nine progressive hole sizes ranging from 1/4 inch to 3/4 inch. It mounts in a 3/8 inch chuck and is built for repetitive sheet-metal work in automotive and fabrication shops. The tool is supplied new and ships directly from the manufacturer.
Who it suits and who it does not
It suits technicians who need to enlarge existing holes or drill multiple diameters in thin steel, aluminium or plastic without changing bits. It is not for buyers who need a single large diameter in one pass, for deep-hole drilling in thick plate, or for impact-driver use where a hex shank is required.
Capacity and headroom
The nine steps cover the common range from 1/4 inch up to 3/4 inch, letting you drill or deburr standard conduit and pipe-entry sizes in one tool. Each step is limited by the flute length, so material thicker than the step depth will require a different bit. The 3/8 inch shank fits most corded and cordless drill chucks, but the straight shank prevents use in quick-change hex adapters.
