Norseman 20540 Type 52-AG 7/8″ Bridge Reamer, Spiral Flute, Hex Nut Shank

The Norseman 20540 Type 52-AG 7/8″ Bridge Length Reamer is a high-quality tool built to meet the demands of structural steelwork, including bridge erection, shipbuilding, and industrial construction. Designed for aligning and enlarging holes in heavy-duty steel, this reamer features a hex nut shank that matches the socket size of bolts driven through the reamed hole, ensuring accuracy and compatibility with rotary impact sockets. The tapered cutting end allows the reamer to enter overlapping and misaligned holes with ease, minimizing effort while improving alignment efficiency. Constructed from high-speed steel (HSS) and finished with a durable black-and-gold oxide coating, this reamer provides exceptional toughness, reduced friction, and extended tool life. Its spiral flute design ensures clean, burr-free hole enlargements, while the extended 9-3/8″ overall length and 7-3/8″ flute length provide the reach and control needed for professional results. Proudly made in the USA, the Norseman 20540 is trusted for its durability, precision, and reliability.
