8 Pc Radius Gauge Set 9/16'' to 1'' Gauges, 3602-5022

Accusize Industrial Tools 8 Pc Radius Gauge Set 9/16'' to 1'' Gauges, nice set of gauges

Does what it's supposed to

These are a pretty decent set of radius gauges, especially considering the price vs. Starrett or another manufacturer. They are somewhat thinner material than my Helios (German) set that goes up to 1/2"...these are roughly 18 gauge material while my better ones are more like 16 gauge. I am using them for fabrication layout, so they seem to be accurate enough for that work (and much better than the plastic circle template I was using. I don't have any way qualify them, so I can't say if the radius is within 0.010" or 0.001" of spec. The case is the typically cheesy Chinese vinyl pouch. All in all, they're good enough for what I'm doing with them.

Seems to be a very nice set for the price. Measuring the thickness of the steel, I get 0.0263in which puts it in the 23 gauge steel range. Best I can find for more well known brands is they are 0.03125in, but I can't confirm that. Either way, that's only a gauge and a half better. These feel pretty sturdy and measuring the diameters of the circles puts them all within a couple thou of the proper size. With a micrometer, the measurements of the diameters are as follows:1" - 2.0012in15/16" -1.8768in7/8" - 1.7506in13/16" - 1.6269in3/4" - 1.5021in11/16" - 1.3774in5/8" - 1.2514in9/16" - 1.1274inAbsolutely nothing to complain about on radii this large. The largest error was +0.0024in and the average accuracy of these is 0.00173in, but that's for diameter. Radius is halved, so +0.0012in and the average accuracy would be +0.00086in. Pretty darn good if you ask me. Starrett's stated accuracy is +/- 0.002" so these are comparable. I didn't measure the internal radius of any of the gauges, but I have to presume they are of the same caliber.The case is the standard blue vinyl-ish case and it doesn't come with any holder. Overall, for the price, you'd be hard pressed to find a better set of radius gauges!

These are of sufficient thickness. The size etching is easy enough to read. Case is adequate. Priced well. Gauges seem accurate when using them to check OD of round tubing and bar stock.

This seems like a good set. I al using them for scribing layouts. I would like to see them made from a bit heavier gauge material but they are not bad, especially given the price.

To me, there are only two things that set a radius gauge set apart from the rest: 1. the accuracy of machining to match the true radius, and 2. how easy it is to read the size labels. I like to be able to read the size labels at-a-glance when I'm busy and want to work fast. This set has thin faint etched labels. So it causes me to slow down a bit so I can double check that I'm using the correct size. I am writing on better labels with a Sharpie pen instead. So I give it 3 stars for being just OK.
