Accusize Industrial Tools 0.2-1.2'' by 0.001'' Inside Micrometer, Satin Chrome Finished, Eg00-3221

Hello all, just wanted to give my experience with the Accusize 0.2”-1.2” inside micrometer. Received 10-31-2020. First, I am a home machinist and do not rely on these tools to make a living. Second, this is an unbiased review, that is, I did not receive this micrometer free or for a discount for a favorable review. I will say that the micrometer I received is very good in all respects. The entire length of travel is very smooth - the satin chrome finish is excellent - the scale marks are clear and well defined - the ability of repeat measurements taken with my Brown & Sharpe height gage are right on - the ability to take different measurements along the full travel proved accurate when measured against my grade A gage block set - the thimble lock holds well. This mic compares evenly with weight and feel to my Starrett outside micrometers. The included standard was accurate when checked with a pin gage. The fit and finish is very good. Is it a 240.00 Mitutoyo, no of course not. Again, I do not rely on these tools to make a living, but for sub 70.00 inside micrometers, I am very satisfied. I will be ordering the 1”-2” next and will provide my thoughts on it as well.

It is not a Mitutoyo but it is close enough for the price differential. Smooth and accurate bang for the buck I have given it a 5.

Good tool for the money. After calibrating with the standard provided, it seemed to read true. The screw is a little rough in places but not that bad. Perhaps a little lubricating oil will fix that.

Never had one of these works well we’re checking inside diameter

Very well made and accurate.

One of these was acceptable, but the other has a loose jaw that could not be tightened to eliminate the play. That said, the design seems almost identical to the Mitutoyo, the barrel is smooth and the ratchet works fine. Also, these are fully adjustable and can be calibrated just like the Mitutoyo 145 using the included spanner. You just rotate the barrel (part with graduations). However, I am not sure how they expect people to know that since there are no instructions and the video on Amazon about how to calibrate has no description.

Perfect 👌

After initial calibration this mic would not give a repeat measurement. It would if you used the main thimble wheel but not if using the ratcheting adjustment, which is what you are supposed to use to dial in a measurement. Also would not repeat initial calibration measurement.
