Stainless Steel Radius Gauge Set, 6Pcs Portable Concave Convex External Internal Arc Measuring Tool for Tool and Die Makers Check （R0.3-1.5/ R1-6.5/ R7-14.5/ R15-25/ R25-50/R26-80）

Quality is good for the price. Curved edges are true and continuous the length of the edge.However, it is difficult to separate some of the blades, especially the larger inside radius set. A better clean up of the edges from the cutting process to remove the bur would help them separate better.A before assembly wash would be nice too, these are covered in oil, and it is a very stinky oil at that.Other than that, seem good for the price

Other than the oily residue, these gauges are perfect. Just clean them up with a dry rag, and you're good to go!

These work great and are cheap. If you’re just looking to check a radius quickly, this is what you need. You will have to deburr many if not all of the gauges but it’s not bad at all. Radius's are accurate and the grease comes off easy if you let it soak in rubbing alcohol.

Excellent

All packed in individual bags, tube.All are heavily coated in oil, they will need an alcohol or other solvent cleaning before use - I work with carbon fiber, so these will go no where near any of my work pieces until they are stripped of this thick oily coat.Upside, all are stamped, not printed. All are clean, no rust.See pictures for a few rough edges and one with a crescent in the gauge.Decent enough, you get what you pay for.

Tools was great to use for some of the jobs .

These are OK. My only real complaint is the marking on some of the blades is very weakly stamped, making it hard to to read. Can't complain for the price. I assume the accuracy is there though I haven't tried to verify it. Construction seems robust enough, the sets are securely riveted together. It's easy to pivot the blades in and out, they aren't overly tight. Covered in stinky Chinese oil, easy enough to clean off.

poor quality. stainless steel that is rusty out of the box. waste of money.
