Up for sale is a premium piece of American industrial history: a genuine Brown & Sharpe No. 576 Hardened and Stabilized precision machinist tool.

​Anyone in toolmaking, aerospace machining, or custom fabrication knows that vintage Brown & Sharpe is the absolute pinnacle of quality.

This isn't cheap modern import steel—this is master-class, stabilized American tool steel engineered to never warp, shift, or lose its precision tolerances over a lifetime of use.

​Condition:

Excellent, exceptionally clean condition. The faces are smooth, the edges are incredibly sharp and crisp, and it has been meticulously cared for in a climate-controlled shop environment. There is very slight, nominal cosmetic wear on the bottom surface from sitting on a surface plate (clearly highlighted in the close-up photo), which has absolutely zero impact on its flawless performance.
