256RL-3
Starrett Disc Type Micrometer
with rotating or non-rotating spindles


These tools are used to measure the thickness of work sections such
as ribs, lands, fins, cutting edges on form tools, and chordal thickness
of gear teeth. Because of their large anvil and spindle faces, the 1"
and 25mm sizes are also useful for measuring the thickness of sheet
materials like paper, cardboard, rubber, and plastics.
