Outside Micrometer, 0-1" Machinist Micrometer, 0.0001" Graduation Micrometer Set, Alloy Precision Micrometer, Machinist Tool, Micrometer Standard with Case

Great for the money spent. Accurate like it is designed. Get a micrometer test block to periodically check the machine zero and make adjustments to the wrench

Great item, almost as accurate as a digital- only have about .0001- .0003 of guessing space. If you tolerance is that low you might need an electron tool (yeah that a joke)

These micrometers worked wonderfully. They are indeed very precise and accurate. Repeatability is well under .0001" (one tenth). The only beef I have is the calibration standards. They should have spherically-ground ends, and be accurate! Instead, what they give you is bar shaped "standards" with flat-ground ends, which make it needlessly difficult to locate them between the carbide anvils properly. As far as accuracy, the 1" standard, using the zeroed 0-1" mic measures 1.0006". From there, the 2" standard, using the 1-2" mic, "zeroed" at 1.0006" against the 1.0006" standard measures 2.0009". Don't expect them to be accurately calibrated out of the box. At least with this set, one can discover and adjust for however much inaccuracy there is in the standards, and calibrate the mics accordingly. I have to think that actually supplying accurate, properly shaped standards really wouldn't be that difficult or expensive though, so I'm deducting a star for that.Of course, all of this inaccuracy could very well be due to not having spherical ends on the standards, and as such being so fiddly that I unknowingly never actually did accurately locate them between the anvils. I'll likely end up getting some better standards and update my review accordingly.The build quality (other than the standards) seem excellent. There is some rough finish on the sleeve of the 1-2" mic I received, but not enough to complain about. The ratchet stop works fine, and the thimble has a smooth, fluid action. The lock is precise and does what it's meant to do without complaint.For the price, I'm keeping them.

Worked as expected. Good build quality. Included gauge blocks to check accuracy. I mainly used the 3-4inch for setting it to standard cylinder bore sizes for my 2AZ-FE engine.

Ease of adjustments, quality made.

When the reading is a dead 0 the . 000x scale should be at 0 also. In my pics this should read . 8750. If I use the 10 thousandth scale in this example I could conceivably come up with. 8759, especially if inexperienced or lacking in common sense. If that sounds nit picky remember these are micrometers advertised as accurate to the 10 thousandth of an inch. These sleeves are junk, rendering the instrument useless. Which is too bad, I would like to find cheap accurate tools.

Bought this for my partner very durable

Accurate, no complaints.
