Bridge reamers are installed in a compatible power tool to enlarge, debur, and finish holes in structural materials to a specific size. The reamers have tapered flutes that ease the tool's entry into rough-cut or misaligned holes. Also called construction reamers, alignment reamers, and car reamers, they are designed for reaming difficult-to-machine materials such as iron and structural steel in metalworking applications where extreme precision is not required. Bridge reamers, car reamers, and alignment reamers are commonly used to ream rivet holes in parts for automobiles, bridges, rail cars, ships, and pressure vessels.
