Great Product--Easy to use

This is probably one of my most used accessories in my home DIY workshop. I have used it to measure heights for router bits, trim spacing, gap measurements and so many other things. Would highly recommend for so many things!

I want to up my woodworking game a bit and one area I felt I could imprive in was accuracy! To that end, I decided to buy a set of these blocks.Now that I have them, I measured them all with my calipers and some are off, but I doubt any are off enough to really impact my overall accuracy, but still, you would expect these gauges to all be accurate. I believe the page said +/- .oo1 inches. Well, they're bot that accurate1/16 = .06253/32 = .09401/8 = .12505/32 = .15653/16 = .18707/32 = .21751/4 = .25005/16 = .31253/8 = .37307/16 = .437015/32 = .4655 *1/2 = .4980 *23/32 = .7170 *3/4 = .7470 *Ok, so you can see most of them are off just a little bit. But, the 4 with asterisks weren't just off, but there was signifinant differences through the length of the block. For example, 15/32 measured .4680, .4665, .4670, .4650, .4675, & .4660 as I measured down the length. It should have measured .4688 so at one end it was only off nearly 1 thousands of an inch, but near the middle it measured .4650 which is off almost 4 thousands.In reality, my woodworking is not that accirate and I dont expect any issues using these, but they should be better.

Really use these a lot, very useful

Very happy with this set.

Great to have for many reasons. I used it to figure out gap at wall for some cornice work.
