12-Step Range
The Walter 01W105 step drill creates 12 distinct hole sizes from 3/16 inch to 7/8 inch in a single pass. It is designed for electricians, plumbers and metalworkers who need to enlarge pilot holes quickly without changing bits. The straight-shank design fits standard 3/8 inch drill chucks. This tool suits professionals who value speed on repetitive drilling tasks.
Build Integration
The 3/8 inch shank locks into any keyless or keyed chuck rated for that capacity, so no special adapter is required. A single bit replaces a tray of individual twist drills, freeing pouch space and reducing change-over time on the job site. It works with corded or cordless drills that deliver sufficient torque for steel. Buyers who need a hex-shank impact-rated version will need a different tool.
Capacity Headroom
The 12-step progression covers common conduit, pipe and fastener clearance sizes up to 7/8 inch diameter. Each step self-centres, reducing walk on thin sheet metal and keeping holes round. Material thicker than the step height may require multiple passes or a larger drill press setup. Users drilling holes larger than 7/8 inch must select a different bit.
