Bridge Reamers are designed for use in structural steel, in the building industry, bridge erection, and ship construction. The cutting end of the flutes is tapered therefore allowing the reamer not only to enter overlapping holes but also permits insertion into very badly misaligned holes. Bridge Reamers are commonly used in portable electric or pneumatic machines
