  • 6" Dial Calipers with counter?
  • Is there a dial caliper with a little window that shows the number of revolutions? If I go to say, .625 I lose track, it'd be nice to see the number 6 in a little window to keep track.

    I thought I used to have one but I can't find it.

  • I used a dial caliper for many years until it failed. Have not figured out a reason to buy another GOOD one.

    Do not buy one from HF. They are no good!

  • thank you for the thoughts and advice
  • I have one digital and one dial caliper and I have a 1" micrometer. For my purpose I find that .001 isn't going to hurt anything. I checked all of them against a feeler gauge and the micrometer indicated what the feeler gauge showed.

    Thank you.

  • Precision only matters in horseshoes and hand grenades. Calipers are good for getting ballpark numbers. For precision readings a micrometer is required -bearing journals, crank OD, et al. For inside diameter, a precision dial bore gauge is the best. ID's and OD's need to be checked, not only for size but for taper and out-of-roundness.

  • Isn't the bar of the dial calipers graduated in 1/10" increments?

    I read the bar to get the number of full inches and the first number after the decimal point. ...The dial gives me the 2nd and 3rd digits after the decimal point.

    I do have a dial caliper which has a smaller dial inside the main dial, but it is easier to read the bar and the large dial.

  • Yes, Bruce. My MITUTOYO 6" (150mm) Digital Calipers have the INCH scale on the bottom rail and the METRIC scale on the top rail of the bar. The INCH scale is marked every .100" by a hash mark and each inch numbered as well. the METRIC scale is also marked every 10mm and marked off as such, 10, 20, 30 et al. I don't know how mush more you need. As I said I do not trust anything digital anyway. I have seen too many errors with digital equipment. I spent over 35 years in automotive manufacturing. From small jobs hops to low volume and very high volume production shops to the assembly lines. One wrong move on a digital mic and you are screwed. The zero button can be pressed by accident and thus all measurements after will be wrong. Part of my job was with QC doing gage calibration and Gage R&R Studies. News Flash: Digital Measuring Devices WIL NOT PASS A Gage R&R Study. A standard Starrett micrometer and the like requires calibration to be done with a special wrench and using JO-BLOKs and/or a set of precision standards. I'll use my digitals when I need a quick ballpark answer like measuring a drill size or bolt size. Otherwise it's my old reliable dial calipers and mics.

  • Digital Dial Calipers: turn on, clean blade and jaws, close, press the 'ZERO' button. Test with a few opening and closings so it geos back to zero when closed. You are now calibrated. Measure your part. If in doubt, keep a Jo-Blok or two handy to verify calibration. I don't trust digital calipers and mics. Forget any counter. Always best to have an alternate measuring instrument.

  • I use digital calipers to measure the overall length of ammo I reload. I have several dummy rounds with the length marked on them that I use to double check thinks with.

  • Re: 6" Dial Calipers with counter?
  • Kinda like a calculator. If you don't have an "idea" what the answer is, either tool can get you in a lot of trouble if you believe the result. These tools just confirm with more accuracy. Your info about zeroing in and checking other positions with a jo-block or other known dimension is right on. My mics are 63 years old and I still check them periodically. I do have a one inch throw dial indicator with a small dial that counts the .100 revolutions. Pretty handy.
