Fowler 54-646-401-0, X-Tender-E Digital Dial Bore Gage Set with 1.4" - 6"/35mm-150mm Measuring Range

Great product, excellent price, very fast shipping

Not very easy to setup but there is a old video on YouTube on setup and calibration. The included instructions are pretty much useless. The tool itself is good quality and does it's job with repeatable results. A set of snap gauges would do just aswell in my opinion though.

If you are just learning it took me some time to figure it out. I couldn't find much help on line for a analog gauge either. You also need some other form of measurment to get your tool into calibration.

It does what I want but not as easily as I had hoped. No directions but what's on utube. I wanted to just run it in and look at the indicator and have it tell me the ID. But it's not quite set up to do that unless I don't know how to access that feature as the difficulty of operational features.I do portable lineboring and getting to withen .001 tolerance is critical and challenging with the tools and equipment designed for lineboring.

Produced same results as much more expensive units.

Ok

The specific accuracy of this gauge is not listed anywhere, so I have attached a picture of the actual certificate that came with the gauge. So the resolution here is useless. Not sure what the point of 0.00005" resolution is good for with a listed accuracy of 0.0006" and repeatibility of 0.0004".

Someone asked if the digital indicator was removable for use with a stand. It is removable and is a fairly standard gage, however it does not have a mounting lug on the back. It is just a straight cover plate. You can replace the plate with another that has a lug.
