Description
Drillco 425A156 7/8 Bridge Reamer Taper Shank is designed for precise hole enlargement and alignment in demanding industrial and structural applications. Commonly used in bridge construction, shipbuilding, and steel fabrication, this reamer ensures accurate diameter sizing for high-tolerance projects. The pilot-type point allows smooth entry and alignment in small or slightly off-center holes. Made from premium-grade HSS with a 135° self-centering split-point, it reduces thrust and walking. The black oxide surface treatment improves durability, while the shorter screw machine length adds rigidity to minimize breakage. The round shank ensures secure fit in drill chucks, and the tool is proudly made in the USA.
