The Starrett 576XR Rounded Anvil Micrometer is useful for measuring the wall thickness of parts such as solid and split bearings, tubing, sleeves, collars, rings, various cylinders, and also measuring from the inside of a hole to an edge. The Starrett 576XR has a rounded anvil that contacts the inside curved surface and a flat spindle for contacting the outside of the work, thus producing single-point contact. This permits accurate gaging of curved surface thickness in thousandths of an inch or hundredths of a millimeter.
