• Supplied in fitted plastic case

The Mitutoyo mechanical disc micrometer uses flat discs constructed of hardened steel in own Japanese facilities to measure lengths of spur and helical gears. The non-rotating spindle prevents workpiece deformation and wear by reducing torque on parts being measured. The flatness and thinness of the discs allow for reliable measurements in tight spaces. A ratchet-stop mechanism provides uniform pressure on a workpiece for precise, repeatable measurements and eliminates over-speed error.
