Norseman 20570 Type 52-AG 1-1/16″ Bridge Reamer, Spiral Flute, Hex Nut Shank

The Norseman 20570 Type 52-AG 1-1/16″ Bridge Length Reamer is engineered for precision alignment and hole enlargement in structural steel applications, making it indispensable for bridge erection, shipbuilding, and industrial construction projects. Designed for professional-grade performance, it features a hex nut shank that matches socket sizes for bolts driven through reamed holes, ensuring secure compatibility with rotary impact tools. The tapered cutting end allows for smooth entry into overlapping and misaligned holes, saving time and improving accuracy on critical alignment tasks. Constructed with durable high-speed steel (HSS) and finished with a black-and-gold oxide coating, this reamer delivers extended tool life, reduced friction, and superior wear resistance. Its spiral flute design efficiently removes material, leaving burr-free, clean holes with minimal chatter. Measuring 9-3/8″ overall length with a 7-3/8″ flute length, it offers the control, reach, and reliability required for heavy-duty applications. Proudly made in the USA, the Norseman 20570 meets the high demands of industrial professionals.
