01P012 - Walter 3/4-Inch HSS Bridge Reamer with 3-Flat Shank

Premium Industrial Hole Alignment Solution

The Walter 3/4" Reamer (SKU: 01P012) is a high-performance cutting tool designed for the rigorous demands of industrial metalworking and maintenance operations. Manufactured in the United Kingdom, this tool represents the pinnacle of European metallurgy, utilizing top-quality High-Speed Steel (HSS) to deliver exceptional durability and cutting precision. It is specifically engineered to enlarge and align existing holes, making it an indispensable asset for structural steel erection, heavy machinery assembly, and automotive frame repair.

One of the standout features of this reamer is its robust 1/2" shank equipped with three precision-ground flats. This design consideration is critical for industrial users, as it ensures a positive lock within the drill chuck. Unlike round shanks that may slip under the high torque required to ream through thick steel or stainless plate, the 3-flat design transmits power efficiently, protecting both the tool and the operator. The reamer's geometry includes a tapered lead, allowing it to enter misaligned or undersized holes smoothly without grabbing or binding, which is essential when fitting up multi-layered assemblies.

Versatility is at the core of the Walter 01P012. It performs exceptionally well across a broad spectrum of materials, including aluminum, mild steel, and stainless steel. Whether you are correcting bolt hole alignment on a flange or widening apertures for rivets, the superior heat resistance of the HSS construction ensures the cutting edges remain sharp longer than standard carbon steel alternatives. For MRO professionals seeking reliability and precision, this Walter reamer offers a solution that reduces downtime and increases productivity on the shop floor.

Technical Excellence

Walter Surface Technologies has built a reputation for creating tools that solve specific industrial challenges. This reamer is no exception, featuring spiral flutes that actively eject chips from the hole, preventing clogging and heat buildup. This results in a cleaner finish and reduced mechanical stress on your power tools.
