Drillco 1-5/8 Bridge Reamer Taper Shank (425A240)

Description

Drillco 425A240 1-5/8 Bridge Reamer Taper Shank is engineered for precise hole enlargement and alignment in demanding structural and industrial applications. Commonly used in bridgework, ship construction, and structural steel fabrication, this reamer delivers accurate diameter sizing for high-tolerance projects. The pilot-type point provides smooth entry and proper alignment into small or slightly off-center holes. Made from premium-grade high-speed steel HSS, it offers exceptional durability and performance. The 135° self-centering split-point minimizes walking and reduces thrust requirements, while the black oxide surface treatment improves wear resistance. Its shorter screw machine length increases rigidity to reduce breakage, and the round shank ensures a secure fit in compatible drill chucks. Proudly made in the USA.
