Drillco 1-9/16 Bridge Reamer Taper Shank (425A236)
Drillco 425A236 1-9/16 Bridge Reamer Taper Shank is designed for precision hole enlargement and alignment in heavy-duty applications such as bridgework, ship construction, and structural steel fabrication. This 1-9/16" bridge reamer delivers exceptional diameter accuracy, making it ideal for creating clean, precisely aligned holes in thick steel plates and structural components. It features a pilot-type point that allows for smooth entry and accurate positioning, even in small or off-center holes. The self-centering 135° split-point reduces thrust requirements, minimizes walking, and improves cutting control. Constructed from premium-grade high-speed steel (HSS), this tool offers long-lasting wear resistance and consistent performance. The black oxide surface treatment enhances durability and protects against corrosion. A shorter screw-machine length increases rigidity to reduce the risk of breakage under heavy loads. The taper shank with round compatibility ensures secure holding in standard tooling setups. Made in the USA for dependable industrial quality.
