Drillco 1-5/16 Bridge Reamer Taper Shank (425A220)

Description

Drillco 425A220 1-5/16 Bridge Reamer Taper Shank is designed for precise hole enlargement and alignment in demanding industrial and structural applications. Ideal for bridgework, ship construction, and steel fabrication, this reamer ensures accurate diameter sizing for high-tolerance projects. The pilot-type point enables smooth entry and precise alignment into small or slightly off-center holes. Crafted from premium-grade high-speed steel (HSS), it offers long-lasting durability and performance. The 135° self-centering split-point minimizes walking and reduces thrust requirements, while the black oxide surface treatment enhances wear resistance. Its shorter screw machine length increases rigidity to help prevent breakage. The round shank ensures a secure fit in compatible drill chucks, and the tool is proudly made in the USA.
