The mechanical disc micrometer uses flat discs made with hardened steel in our own Japanese facilities to measure lengths of spur and helical gears. 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.
