Spindle and anvil discs are .032" thick at the edge, tapered to 1/16" at the center, making it ideal for measuring fins, lands, rib, cutting edges and other difficult-togage sections. Accurate measurements to .001" can be taken on paper, rubber, plastics, and other materials with this micrometer. Anvil and spindle faces are lapped flat and parallel over the entire disc surface.
