Description
Drillco 420A220 1-5/16 Bridge Reamer Taper Shank is engineered for precise hole enlargement in bridgework, ship construction, and structural steel fabrication where exact diameter control is critical. A pilot-type point provides accurate alignment and smooth entry into small or off-center holes, while a 3-flute design improves centering and finish quality. The reduced shank paired with 3 flutes makes this reamer well-suited for portable drilling applications.
