Round-Shank Reamers for Hole Alignment with Safety Collar
A collar on the shank prevents you from reaming past the cutting edge. These reamers are for use with hand-held electric and air tools. Also known as bridge reamers, car reamers, and aligning reamers, they ream, true, enlarge, align, and debur holes. All have tapered ends for easy entry into misaligned holes. They are not for reaming tapered holes.
