The ratchet thimble on Mitutoyo’s mechanical outside micrometer delivers a smoother, constant measuring force on the spindle to ensure accurate, repeatable measurements. The combination of the ratchet thimble and speeder enables a rapid spindle feed when measuring a wide range of different dimensions or easier, one-handed measurements.

• Ratchet functions works both from the thimble and speeder allowing easy one-handed operation
• Carbide measuring faces on the spindle and anvil resists wear to keep surfaces flatter with longer accuracy
• Heat-insulated frame minimalizes thermal expansion for consistent measurements in different environments
• Speeder is always available for quick rotation of the spindle
• Measuring force is 5-10N
• Includes a standard bar except for 0-25mm / 0-1” models
• Provided with Mitutoyo Certificate of Inspection
• Supplied in a plastic, fitted case
