Top 5 Digital Micrometers for Machinists

June 25, 2019 1:05 pm

Micrometers are one of the most important tools for any machinist. They are extremely precise tools that, if well maintained and accurately calibrated, will last forever. Ask anyone in your job shop how old their mic is, and you’ll find out that most of them will have likely been around for decades.

Micrometers, like other tools, tend to be passed down from father to son or from retiring mentors to young apprentices. If you are one of the lucky machinists who inherited such a valuable instrument, the only advice we can give you is to take good care of it.

If you are not one of them—or you are one of them, but you are considering purchasing a new model—we are here to help you find the best digital micrometer for your needs.

Digital micrometers, unlike their analog counterparts, have a digital display that makes it easier to read measurements. If you are looking for alternatives to digital mics, check out our ultimate guide to micrometers.

When it comes to precision tools, our advice is to always invest in a tool that will last long and measure precisely and consistently. We understand, however, that sometimes your budget might not allow that, so we’ve included some more affordable models that will also help you get the job done.

Here are the top five models that we recommend:


5. iGaging 0-1″ Digital Electronic Micrometer

Ideal for machinists on a budget, the iGaging Large Display Digital is an easy-to-read micrometer for measuring very small items. Connect it to a computer’s USB port to input the dimensions directly into your favorite design program.

    You didn’t even mention how much faster it is to run the thimble in and out on a quantumike. It’s game changing.

  • I have found that the Mitutoyo brand of digital micrometers is the best when it comes to repairing them. They have the best parts drawings and the best in stock availability of all of their parts. Straight forward to repair also.

    Quantamike is the pinicle in today’s market, none of these other micrometers even come close at the moment

  • Eddiet20 says:

    Agree with all above, I have been an instrument repair tech for 30+ years, originally trained at Mitutoyo, Starrett and those cheap chinamade micrometers are just garbage…

    +1 Quantumike.
    I only wish they had the larger ones at a more reasonable price aaaaand more availability.

    The Mit digi’s are the heads and shoulders best IMO.
