Norseman 20520 Type 52-AG 3/4″ Bridge Reamer, Spiral Flute, Hex Nut Shank

The Norseman 20520 Type 52-AG 3/4″ Bridge Length Reamer is a heavy-duty tool designed for aligning and enlarging holes in structural steel applications. Perfect for bridge erection, shipbuilding, and industrial construction, this reamer features a hex nut shank that matches the socket size for bolts driven through reamed holes. Its tapered cutting end allows smooth entry into overlapping and misaligned holes, reducing alignment time and ensuring clean, accurate results. Manufactured with high-speed steel (HSS) for superior strength and durability, the reamer is finished with a black-and-gold oxide coating to reduce friction, increase lubricity, and extend tool life. The spiral flute design efficiently removes material, producing burr-free, precise hole enlargements. With an overall length of 9-3/8″ and a flute length of 7-3/8″, this bridge reamer provides extended reach and control for professionals in structural steelwork. Proudly made in the USA, it meets the highest standards for quality and reliability.
