The Mitutoyo mechanical disc micrometer uses flat discs constructed of hardened steel in our 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.
- Available in Metric and Inch models
- Ratchet mechanism provides an audible click to ensure measurement is performed at a constant force
- Knurled friction thimbles provide quick adjustments even when wearing gloves
- Satin chrome finish on the sleeve and laser etched measurements on thimble for easier reading
- Frame has a baked enamel finish for durability and longer lifespan
- Supplied in fitted plastic case
