Features & Benefits

The Mitutoyo gear tooth micrometer measures the over-pin diameter of gears. Precision carbide anvil and spindle ball-tipped measuring surfaces are interchangeable, with optional ball-tip faces allowing for measurement of various gear modules. A ratchet-stop mechanism provides uniform pressure on a workpiece for precise, repeatable measurements. Readings are displayed on an easy-to-read LCD readout.

  • Available in Metric and Inch/Metric models
  • Interchangeable ball anvil-spindle tips for various gear modules (0.5-5.25) are optional
  • Ratchet mechanism provides an audible click to ensure measurement is performed with a constant force
  • SPC output function allows for quick and easy data management in real time
  • Functions include Zero/ABS Setting, Data Hold, Data Output, Function Lock, 2 Presets, and inch/mm conversion (on inch/metric models only)
  • Alarm: Low Voltage, Counting Value Composition Error
  • Satin chrome finish on the sleeve and laser etched measurements on thimble for easier reading
  • Frame has a non-slip finish for better grip in shop environments
  • Includes a standard bar except for 0-25mm and 0-1” models
  • Supplied in fitted plastic case (models over 150mm have a wooden case)
