Top 5 Digital Micrometers for Machinists
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:
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.
A surprisingly reliable micrometer at an affordable price. The hard carbide tips make it more durable than other models in the same price range.
The brand says it all. Investing in a Starrett micrometer means investing in quality and durability. Without any doubt one of the best models in the market.
This micrometer’s electronic microprocessor can hold measurements at any position, convert to absolute value, set a temporary zero position, and return to a true zero reading.
One of the most appreciated brands by Practical Machinist’s members. The Mitutoyo 293-185 Quantumike is IP65 coolant proof rated and features carbide-tipped measuring faces suitable for use in harsh working conditions. You can take accurate, reliable readings with its consistent pressure.
In the end, micrometers are instruments that will stay with you throughout your career.
Choose your model wisely, use it carefully and calibrate it frequently. Follow these three easy pieces of advice and you will see that your investment will pay off.
