Mitutoyo 505-742J Dial Caliper, 0.1" per Rev, 0-6" Range, 0.001" Accuracy

The Caliper is excellent. It came accurate out of the box. It feels like a high quality product in your hand and has nice smooth movement. I am very happy I decided to go with this high end caliper even though i'm just a D.I.Y.er.

As expected of Mitutoyo, a high quality, very precise instrument. Super repeatable; that first image is after running it out to 6", back and forth a couple times, and then back to zero. Seems like it has no backlash at all. What more could you ask for from a caliper?No word yet on durability, I'll update the review if it develops issues after a while. No news is good news.I bought this as a replacement for my cheap digital caliper, which measured fine, except every time I wanted to use it, the battery was dead. Back to analog.One thing to note is that the case does not come with any foam. While the dial does say "shockproof", I take that with a grain of salt. I modified the case with some 3M UHB double sided foamy tape stuff and it brings me peace of mind. One other reviewer mentioned this and padded his own case.It also does not have a barrel hinge, and instead just a thin piece of plastic. I would imagine after opening and closing it ten thousand times, it would cold work the plastic until it broke, like bending a paper clip back and forth until it breaks in half. Maybe they use magic plastic that won't work harden, what do I know.

The dial readout is very crisp and easy to read; it is marked for every 0.001" (one thousandths). It is easy to interpolate by eye to 0.0005" (five ten thousandths) and probably to 0.00025" (25 one hundred thousandths). I am very pleased and used these to identify a ten thousandths error in a recently purchased replacement part.I love the dial readout. It is much easier to read than a vernier scale. I prefer the dial to electronic readout since there is no battery to go dead while the tool sits in my tool drawer. This is the perfect choice for users that only occasionally make measurements with this level of precision. Be sure to read and follow the card in the plastic envelope: wipe the calipers down with a lightly oiled rag to remove the shipping preservative. It will slide much more smoothly that way.Just buy it! The quality is a joy to use.

Absolutely worth every penny of your hard-earned money. This thing is great it is built to last and will certainly pay for itself. This is my first set of good dial calipers and I am very impressed and will never waste my money on cheap tools again. The package arrived on time in good condition not a scratch on the calipers. Zeroed immediately and repeated every time I opened and close the Jaws. Fit and finish are excellent and flawless. Super smooth easy to read just great. Passed inspection and calibration at the shop flawlessly. Will get lots of use out of these.

Accurate, durable, long life, and comes in a protective storage box. I’ve been using these products personally and professionally for decades and have no complaints. A perfect example of why buying quality tools is the only way to go.

I went through two digital electronic readouts that broke before I reverted back to this. No problems. If it ain’t broke don’t fix it. If handled carefully these can last a few lifetimes. My original I had over fifty years and I gave it to my son. Runs fine.I thought since I am older to try digital almost ten years ago, they broke, just sitting there and used a few times a year.

Caliper is very well made and very accurate. The Amazon description does not state that it comes in its own carrying case, but it does. You need to watch the demonstration video to see the case. Its not a tight fit so you may want to put a thin layer of foam in the case to keep it from bouncing around. You would think for the price of this unit the manufacturer would supply a case that's padded.

What is there to say? You can measure a human hair with this thing. The Mitutoyo caliper is known around the world for its incredibly high quality and scalpel-like precision. The price is shockingly affordable for something so accurate and well made.
