Glarks 4 Pack R0.3-1.5/ R1-6.5/ R7-14.5/ R15-25 Radius Gauge Set, Stainless Steel Radius Fillet Gage Portable Concave Convex Measuring Tool for Tool and Die Makers Check

I was using my friends set he bought a lot for technical drawing and he cut me off but sent this link. Love them and are such a handy tool to have when you need to get measurements.

I recently purchased a set of radius gauges, and I must say, I'm quite pleased with their performance. These gauges are undeniably sturdy and seem built to last, which is a major plus for anyone who works with precision instruments. However, my overall experience was somewhat dampened due to the unfortunate arrival condition.Let's start with the positives. The build quality of these gauges is outstanding. They are robust and durable, making them ideal for the demanding tasks I use them for. The measurements are accurate, and they provide consistent results, which is crucial in my line of work.However, the reason I couldn't give these gauges a full 5-star rating is the rather messy and unpleasant surprise I encountered when unboxing them. The gauges arrived covered in machine oil, and it wasn't just a light coating; they were drenched in it. The oil had a strong, unpleasant odor that lingered in my workspace for quite some time.Removing the oil was no easy task. It had seeped into all the nooks and crannies between the individual gauges, making it a time-consuming and somewhat frustrating process. I wish the manufacturer had taken more care in packaging these gauges to prevent this issue.In summary, these radius gauges are undoubtedly sturdy and perform admirably once you manage to clean them up. They are a valuable addition to any toolkit for those who prioritize accuracy and durability. However, the messy and smelly machine oil issue upon arrival is a significant drawback that can't be overlooked. With a bit more attention to packaging, these gauges could easily earn a perfect score.

I guess I don't have anything to compare against to verify the tolerances on these but its an extremely handy/convenient set to have

Exactly what I was looking for and a good price.

Like others have said it was dripping with oil. Mine had machine oil but it wasn't literally dripping. I tried to wipe them clean, but I gave up since it'd still be in the between each leaf. Some being hard to swivel out because some pieces were slightly bent. So I took the difficult time to take off the rivets with pliers because I don't have the tools to easily. (Got a blister from doing that. And I think it's a rivet but hollow ones.) I'm going to 3D print some cases for it instead.The quality is cheap. Had a missing number on one. Not all are aligned the same, as in some were cut a little short so they don't align perfectly even though they are in order or the holes being aligned. Some were cut that the diagonal edge on the measure side wasn't the same angle. Some size indicators are flipped the other way and a few just visible enough. I have one that's blank. A few have blotches of what appears to be rust--I don't know if they are really.Too bad it's not like there are other better options on Amazon. I got this because there was more people reviewing, but they all seem just about the same quality. I would be more than happy to pay a little more for a more better quality set.

First, the Pros and Cons...Pros: Inexpensive, fast delivery, wide size range, both concave and convex gages.Cons: Heavily coated in light machine oil (stainless steel?), grit in between leaves, a couple doubled up leaves (two of the same size), some marked heavy and others marked light with size indication, some leaves are reversed in the stack so size indication on opposite side.They come in a little plastic box that seems somewhat study. Inside the box the gage sets where individually wrapped in a protective plastic coverings. When removed from the coverings it is evident that they’ve been coated in a light protective machine oil which kind of surprised me if they are stainless steel. I did a quick check each set and noticed two sets had doubled up leaves (leaves of the same size) but I didn’t see any missing sizes. Upon moving the leaves around in the sets I noticed all were contaminated with some sort of fine grit.Once I checked the all I wiped them all down with a clean rag to remove the excess oil and grit on them. Then I mixed some dish soap in some hot water and placed the gages in there to soak for 15 minutes. When I came back two of the sets had a light tarnish on them, not rust but more of an etching. This was present on many of the leaves and the side plates of the holder, but one set of the five was actually beautiful and shiny.For the price you really can’t complain. I’m not using these for machining or precision work, they’ll be used for replicating models and such for 3D printing. So really they aren’t a bad value.

Mediocre stuff made in China with little bits of bent metal covered in machine oil and slightly rusty. They’re cheap but I can’t recommend them
