Drillco 1 Bridge Reamer Taper Shank (425A164)
Drillco 425A164 1 Bridge Reamer Taper Shank is engineered for precision reaming in demanding applications such as bridgework, ship construction, and structural steel fabrication. Designed for extreme diameter accuracy, it features a pilot-type point for smooth entry and precise alignment in small or off-center holes. Made from premium grade HSS, it provides long-lasting durability. The self-centering 135° split-point reduces walking and thrust, while the black oxide surface treatment extends tool life. Its shorter screw machine length adds rigidity to minimize breakage, and the round shank allows compatibility with standard tooling. Made in the USA, this reamer delivers reliable performance in industrial environments.
