Teper bridge reamers (Figure H-122) are used in structural iron or steel work ,bridge work, and ship construction where extreme accuracy is not required. They have long tapered pilot points for easy entry in the out-of-line holes often encountered in structural work. Taper bridge reamers are made with straight and helical flutes to ream holes with diamiters from 1/4 to 1 5/16 in.
