01P005 - Walter 5/16-Inch High-Speed Steel Aligning Reamer

Heavy-Duty Solution for Misaligned Holes

Fabricators and welders know that in the real world, holes don't always line up perfectly. That's where the Walter 5/16" Reamer (SKU: 01P005) comes in. This rugged aligning reamer is the ultimate "fix-it" tool for your shop or job site, designed to quickly re-size and align holes in mating metal parts. If you are assembling truck frames, installing structural beams, or repairing heavy machinery, this tool allows you to quickly prepare holes for bolting without the frustration of binding or stalling your drill.

Built for use with standard portable power drills, this reamer features a robust 3/8" shank equipped with three flats. This design feature is a game-changer for welders working in the field; it locks the bit into the drill chuck, preventing the annoying and dangerous spinning that happens with round-shank bits under load. The reamer is crafted from top-tier High-Speed Steel (HSS), giving it the toughness to cut through mild steel, stainless steel, and aluminum without losing its edge. Its spiral flutes are designed to eject chips rapidly, keeping the cut cool and preventing the tool from jamming in deep holes.

The tapered nose of the Walter 01P005 allows for easy insertion into holes that are slightly off-center, self-centering the tool as it begins to cut. This makes it incredibly user-friendly and efficient, saving you valuable time on assembly tasks. Unlike standard drill bits which can grab and snap when enlarging holes, this reamer cuts on its side margins, providing a smooth, controlled expansion of the hole diameter. Add the Walter 5/16" Reamer to your toolbox today and experience the difference that a professional-grade alignment tool makes in your daily fabrication workflow.
