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.
