Taytools 0-6”, 0-150 mm, Digital Height Gauge, Electronic Height Gauge, 0.0005” Resolution DHG

As a knife maker I need something that was quick and easy to make center lines on my blades. This works great!!

Handy for sure

For the money, it does the job. I needed a basic height gauge for knife making, it works. I wish it was carbide tipped but for annealed steel it works ok. Decent weight. Doesn’t feel too flimsy.

I read all of the reviews, and am convinced that many people either expect a $40 measuring tool to have the same quality as a $500+ tool, or they just like to be nay-sayers, or don’t know how to use it. This is a fine height gauge for $40. I am totally pleased. Of course it needed some calibration (it was not square to the base) but by loosening a set screw and using an engineers square on a surface plate the problem was quickly solved. Regarding the flatness of the base, mine was fine. If there is anything lacking, I would say that it takes some patience to set the gauge to a specific height since it doesn’t have a good micro adjustment feature. Just as you would set a caliper for manual scribing, the same process is required with this tool. No big deal. Learn how to do it, practice, and you won’t be frustrated. I would recommend this product to anyone who, like myself, has a home machine shop working to reasonable tolerances. I don’t plan on making parts to a +/- 0.0001” tolerance since my lathe and mill are not capable of doing so. I do, however, expect to make parts that are within +/- 0.001” and this height gauge is sufficient for that task.

Was a but skeptical at purchase more than a year ago but it keeps doing its thing and doing it well. Nice heavy base for stability.

The base on the surface gauge was slightly wobbly as was stated in one of the reviews. I was planning on polishing the base anyway...It took me about 15 minutes with a makeshift surface plate and some 400 grit sandpaper to level it out. After that, some 1000 grit to polish it up and it works very nicely. It glides on the surface plate now. I might go to some 2K grit. The reason for polishing…less wear on the granite surface place. You want the gauge base to glide instead of scrape off the material of the surface plate.I checked the gauge with my 1-2-3 block and got exactly that. 1.000”, 2.000” and 3.000” with the block around 80F. Not bad for a poor boy setup. Consider thermal expansion. At 68F, all sides were shy .001"+-. So maybe the block was ground and measured at 80F, dunno. Repeatability was good.

It’s not perfect, but the accuracy is dead on. It’s not as smooth as higher end units, but it repeats well and reads exactly on gage blocks to less than 1/2 a thousandth. For the price it’s not a terrible option. The reference surface isn’t perfectly flat, but it’s close enough to not be a problem. I don’t expect hand scraped precision in this price rage so it’s fine for what it is.

These look like the real deal, but unfortunately the pair I ordered fell way short of the mark. The bases are not ground flat. Not even close. They wobble on a surface plate. The attached photo shows two of these being held back to back.I've had reasonable results from other height gauges in this price range on Amazon, but these were utterly useless.
