Spherical Face Micrometer-Spherical Anvil & Spindle

The Mitutoyo spherical face micrometer measures the thickness of curved parts within +/- 0.0001” for accuracy and displays readings on an analog mechanical counter. Available in inch or metric units.

Features & Benefits

The Mitutoyo spherical micrometer is available with either a spherical face on the anvil and a flat spindle measuring surface or with spherical measuring surfaces on the anvil and spindle, depending on the application. A ratchet-stop mechanism provides uniform pressure on a workpiece for precise, repeatable measurements and eliminates over-speed error. The micrometer has a measurement range of 0 to 1.0″ (0 to 25.4mm), resolution of 0.00005″ (0.001mm), and an accuracy of +/- 0.0001″

  • Available in Metric and Inch models
  • Available with spherical anvil and flat spindle or with spherical anvil and spherical spindle
  • Measurements are displayed on a mechanical analog mechanical counter on the micrometer’s frame
  • Designed to measure the wall thickness of various tubing, curved parts and pipe wall thickness
  • Spherical measuring faces are 0.59” in diameter and carbide-tipped for durability
  • Ratchet mechanism provides an audible click to ensure measurement is being performed at a constant force
  • Satin chrome finish on the sleeve and laser etched scale on thimble for easier reading
  • Frame has a non-slip finish for better grip in shop environments
  • Includes a standard bar except for 0-1” and 0-25mm models
  • Supplied in fitted plastic case
