Stock up your shop so you always have the measuring range you need. These micrometers come in a convenient case to store and organize them in one place.
To find your exact measurements, read the scales on the sleeve and thimble. These micrometers are free of electronic components that could break if dropped or short-circuit if wet. You don't have to replace any batteries, so they're always ready for the job.
Mitutoyo—The go-to for machinists and engineers. Every part is made within a Mitutoyo automated factory and tested in-house in Japan. The spindle glides as you turn the thimble with a weighty, silky-smooth feel.
Starrett—Precision machined and tested in the U.S. These Starrett micrometers come packaged in their iconic wood case, so you'll be able to spot them on the busiest of bench tops.
Calibration Certificate—Choose these micrometers when precision measurements are required for quality control or by regulation. The certificate is traceable to NIST, so you can be confident your measurements are correct and consistent.
Friction Thimble—Control how tightly the spindle closes on your part without the risk of damaging it. You can keep extending the spindle in small increments once it reaches your workpiece but not enough to overtighten. The thimble will start to resist turning to let you know you’ve applied the right amount of pressure.
Ratchet-Stop Thimble—Best for consistent, repeatable measurements. The spindle stops extending the moment it reaches your part, so it won’t overtighten. Hear and feel a satisfying click that confirms you’ve applied the right amount of pressure.

Coolant-Resistant Wide-Range Digital Outside Micrometers
![]() |
Check different-sized parts as you machine them without swapping between tools. These micrometers come with multiple anvils that you switch out, so you don't need to lug around a case of micrometers. Whether you're milling or drilling, the display and battery cover are tightly sealed, so spraying and dripping coolant won't seep in.
With an LCD display, these micrometers give instant measurements—no need to read scales. Swap between inch and metric or set the position to zero, all with the press of a button. You don't need to reset the zero point since they retain their position when turned off, also known as absolute (ABS) positioning.
Mitutoyo—The go-to for machinists and engineers. Every part is made within a Mitutoyo automated factory and tested in-house in Japan. The spindle glides as you turn the thimble with a weighty, silky-smooth feel.
With SPC Data Output—Send measurements to a computer or data processor to store, analyze, and manage data. You'll need a data cable or SPC wireless transmitter and receiver.
Calibration Certificate—Choose these micrometers when precision measurements are required for quality control or by regulation. The certificate is traceable to NIST, so you can be confident your measurements are correct and consistent.
Ratchet-Stop Thimble—Best for consistent, repeatable measurements. The spindle stops extending the moment it reaches your part, so it won’t overtighten. Hear and feel a satisfying click that confirms you’ve applied the right amount of pressure.
