are they for real ?
$89 gets u a set with that, plus base, arms and 1" dial digital indicator. Right on their home page ... There's probably 2 shops in the whole nation that can hold these types of tolerances, but still I am sure many of us wouldn't mind having 5 h-th of resolution. |

There's probably 2 shops in the whole nation that can hold these types of tolerances, but still I am sure many of us wouldn't mind having 5 h-th of resolution. That they can resolve to .00005" through circuitry in no way means that they will be capable of making measurements to the same degree of resolution. My personal opinion is that they would be worthless for that purpose. Calipers are prone to considerable error----often not able to resolve to a thou, regardless of the capabilities of the electronics. There's too much mechanical error in them----including variations from inside/outside jaws, and springing of the jaws. Holding tight tolerance isn't beyond the capability of many shops. I've worked as closely as .000020", but I had the luxury of a certified secondary standards lab at my disposal to do the measuring. It's almost impossible for the normal shop to measure that close. I drew the line at .0001" tolerance when I ran my commercial shop. Anything closer than that was no-bid, citing my lack of ability to measure reliably. Harold |

Anyone besides me ever have a brain fart like that? Sigh. Harold Uhhhmm, Harold... Do you figure that the header that reads, among other things, "caliper" might've done it? BDDT Cheers Trevor Jones Chuckle! Thanks, Trevor. One right after the other with me, eh? When I read the comments without reading the title, I was at a loss to explain my post. Yes, indeed, I did read caliper, and went off on my tirade about their inability. My comments still stand, but I get the idea that calipers are not what was really intended to be referenced by the OP. Harold |

All told, this is kind of a strange ad. If you hit the page with the
ad: http://www.kbctools.com/usa/main.cfm and read the fine print, it says that the 0.000,05 accuracy is claimed for the caliper ONLY. The included electronic dial guage is only good to 0.001. Kind of backwards from the usual thing; I'd expect a caliper and dial set to either have the same resolution, or the finer resolution to be with the dial, not the caliper. Plus, as Harold noted above, you're unlikely to actually get 0.000,05 out of a caliper anyway. Go figure :-) Dave |
