Walter 1/2-Inch HSS Bridge Reamer with 3-Flat Shank

Heavy-Duty Solution for Misaligned Bolt Holes

Every welder and ironworker knows the frustration of steel erection or heavy assembly: you get the beam or plate in place, but the bolt holes just won't line up. Forcing a bolt through damages the threads and compromises the joint. The solution is the Walter 1/2" Reamer (01P008), a heavy-duty hole alignment tool designed to cut through the toughest fabrication challenges. Unlike standard drill bits that can grab and snap when widening a hole, this reamer is built to shave metal away smoothly, correcting alignment issues in seconds.

Built from high-quality High-Speed Steel (HSS), this reamer is tough enough to handle the heat generated when cutting through thick structural steel or stainless steel plate. It features a tapered nose that finds its way into overlapping holes that aren't perfectly concentric, guiding the cutter through to create a clean, perfectly sized 1/2" passage for your fasteners. This tool is indispensable for anyone working in steel fabrication, truck body manufacturing, or heavy equipment repair.

Walter has addressed one of the biggest annoyances with large diameter cutting tools: shank slippage. The 01P008 features a 1/2" shank with three machined flats. When you tighten your drill chuck, the jaws lock onto these flats, creating a positive drive that cannot slip. This means you can apply the necessary pressure to get the job done without stopping to retighten your chuck. Whether you are working with aluminum, stainless, or mild steel, this reamer delivers the aggressive cutting action and long service life that professional welders demand from their consumables.

Why Welders Choose This Reamer:

• Fast Alignment: Quickly fixes misaligned holes in structural joints.
• No Slipping: The 3-flat shank locks solid in your drill.
• Tough Construction: HSS body stands up to abusive job site conditions.
• Multi-Metal Use: One tool for steel, stainless, and aluminum jobs.
