Champion 980-1 1" HSS Straight Flute Taper Shank Bridge Reamer — Structural Steel Hole Alignment
The Champion 980-1 is a heavy-duty 1" HSS straight flute taper shank bridge reamer designed to enlarge and align off-size, misshapen or misaligned holes in structural steel. This individual reamer is the exact 1" diameter and is suited to bridge fabrication, steel erection, shipbuilding and heavy maintenance work.
The straight flute and right-hand cut provide controlled material removal and a rigid cutting action. Straight-flute bridge reamers are also easier to hand-regrind and easier to dislodge if they become bound in a hole. The taper shank is designed for power tools with Morse taper spindles.
