Description

Drillco 425A224 1-3/8 Bridge Reamer Taper Shank is engineered for precise hole reaming in demanding applications such as bridge construction, shipbuilding, and structural steel fabrication. Featuring a pilot-type point, this tool ensures accurate alignment and smooth entry into small or slightly off-center holes. Made from premium grade high-speed steel (HSS) with a black oxide surface treatment, it delivers durability, resistance to wear, and long-lasting performance. Its shorter screw machine length increases rigidity to reduce breakage, while the round shank provides stable operation for both portable and stationary setups.
