Mitutoyo 293-340-30 Digital Micrometer, Inch/Metric, Ratchet Stop, 0-1" (0-25.4mm) Range, 0.00005" (0.001mm) Resolution, +/-0.00005" Accuracy, Meets IP65 Specifications

These are of excellent quality. The fact that you get a metric and a standard mic for the price of one, with the quality that Mitutoyo is known for, was enough to justify the purchase. This is a one-of-a-kind tool because of the DRO. Mitutoyo provides a one-year warranty and an inspection certificate. br>One feature that I particularly enjoy is the ability to set the dro to zero. Any measurement will be shown as the difference between the size of the gauge block and the part you're measuring if you start with a 0 on a gauge block. The only regret I have is that I did not purchase these sooner. br>br>However, the case they provide is rather cheap, and if you don't add some foam yourself, the micrometer will shake inside.

Simply zero your part at the dimension on the print, and you'll be able to see if you're within tolerance in no time. Because it's easier to read than regular mics, this has helped me speed up my work a little. It's still preferable to be able to read the graduations on a mic rather than relying on the readout 100% of the time, but if you need to read in tenths or millionths, the readout is the only option. br>br>A big plus is the hold button. When taking blind measurements, there's no need to be concerned about scratching parts. br>br>My only minor quibble is the speed with which the barrel changes measurement, but I should have gotten the quantumike version instead if I wanted it to move faster. But knocking a star isn't enough because I knew it was like this when I bought it. If you're not used to the size, the longer length compared to a regular mic will take some getting used to. I still recommend it to anyone looking for a good microphone. Mics quickly pay for themselves if used on a daily basis at work.

After that, you're in the micrometer's noise region. 0001" Because you can't reach the ratchet end of the spindle with the same hand as you can with a Starrett mechanical micrometer, I only gave it a three-star rating. In addition, the Starrett has a better feel for the measuring point than the Mitutoyo. Perhaps it's because the spindle is made of plastic rather than metal, and the threads aren't as good. You can't even take the spindle out to oil the threads. It's a good deal for the money, but I'll stick with my Starretts.

This microphone is fantastic! It's silky smooth and crisp, and the digital readout is lightning fast, repeating to less than a tenth of a second every time. Because it is a little old school and avoids the fancy battery things, the mic is still marked with the same old vernier scale as any other Mitutoyo mic if the battery goes out. With this mic, you can't afford to lose. Buy it.

This Mitutoyo micrometer set is without a doubt one of the best you can get at this price point. As long as the faces are kept clean, measurements are extremely consistent and accurate. This set has been in my possession for nearly three years, and the battery is still functioning properly. Granted, I only use it on occasion, but it's comforting to know that you have a high-quality tool at your disposal. br>The DRO is excellent, and the in/mm conversion is extremely useful, as micrometers are almost always analog in comparison to calipers in my experience. The analog scale was uncalibrated out of the box, so they didn't pay much attention to it. br>One feature I'd like to see is a vernier scale on the sleeve as a backup in case the battery dies and you don't have a spare. I also enjoy using a vernier scale from time to time for the sake of experimentation. br>br>(1/27/18): br>br> After a little more than three years of moderate use, the battery finally died.

One of the reasons I bought it was because it is easy to misread an analog micrometer if you don't use it often. br>Mitutoyo has a great reputation, so much so that there are counterfeit versions from the far east. In the context of, adding and subtracting numbers. If you're not familiar with 025, it's a cheap way to protect yourself from destroying a part you're working on.

This was bought for everyday use in the home. We probably don't need this many micrometers, but we wanted to invest in a high-quality tool that would last, and this Mitutoyo micromoeter fits the bill. It's simple to use, and it's also simple to remove the battery when you're not using it to extend its life. The ratchet mechanism is fantastic; when the ratchet is used to zero the tool and take measurements, the readings are extremely accurate and consistent. It's convenient to be able to switch between inches and millimeters on the digital readout, and it's also nice to be able to use it as a purely analog (mechanical) device. br>br>The battery is one minor drawback; it appears that purchasing a genuine 938882 replacement battery when the time comes is essential. The genuine tool battery has a flat discharge characteristic, minimal voltage sag, and the tool performs consistently until it is nearly dead. The low-cost SR44 replacements, which cost $1 each. 50 to $1. When the battery is new, it works fine, but as it is used, the voltage drops gradually, resulting in erratic behavior when the battery is partially discharged.

At work, I frequently use these. Instead of borrowing everyone else's mics, I needed a set of my own. Almost every day, I use a pin to check my pair. They're activated gauges. Despite the fact that no print I've ever seen has ever mentioned a ridiculous tolerance for millionths. These will suffice; however, I gave them a four-star rating because the tenths should be printed on the barrel as well, rather than being digital only.
