SERIES 169 Disc Micrometer-Non-Rotating Spindle

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
