505-742J Dial Caliper, 0-6" Range, 0.001" Accuracy, 0.1"/Rev, Smooth Dial Movement with Shock Protection, Lock Screw, Improved Readability, Measures OD, ID, Depth & Steps

Mitutoyo is a leader in highly accurate, tough, and well designed measuring equipment. Ask any machinist/inspector in the industry and they’ll all agree Mitutoyo is top shelf quality. I have used Mitutoyo and Starrett and find both to be of equal quality.

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.

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.

One of the best calipers on the market! I’ve had it for years and haven’t had an issue yet.

Clean off the shipping oil and these are a joy to use. Accurate, and repeatable measurements.

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.

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.

Accurate enough for what I do . Convenient and easy to read.
