About Reamers

Morse Taper-Shank Reamers for Hole Alignment

Use these reamers in stationary machines to ream, true, enlarge, align, and debur holes. They’re also called bridge reamers, car reamers, and aligning reamers. All have tapered ends for easy entry into misaligned holes. Do not use for reaming tapered holes.
