10 Pcs Hollow Cup Diamond Burr - 3/32'' Shank Diamond Mounted Grinding Burs Stone Carving Sets for Rotary Tools Includes Dremel

So far they are holding up fine. Good assortment of sizes in the pack. Just take note that its not a full 1/8 diameter shaft, so they won't fit a standard Dremel collet.

I’ve been to big box stores and 1 of these bits costs over 10 dollars and you get 13 and the quality is comparable sitting next to the name brand and it works flawlessly. I was in desperate need for a very small circular cutting bit for my dainty tension rings and I couldn’t be happier! I highly recommend.“Peace “

These bits take some getting used to. I'd recommend trying them out on a scrap piece before going straight into whatever you are working on like I did lol They seem to hold up fairly well for the price. I kind of wish they included a couple more of the bigger sizes rather than the tiny ones but that's probably just me being picky. I would purchase them again.

First time I ever bought this type of product so I have nothing to compare to. It works well on soft wire.

I found literally the exact same thing on Temu for ~$2.

Very nice but returned because the shaft did not fot our dremel.

I Bought these to round off the sharp edges on the prongs on my jewelry. I thought they would work perfectly. They do not. They are not working on my soft metals though I'll say they do work perfectly on wood. I bought these for use on silver and gold and they are not working.

These have been very good for engraving, I like the cup shape and the Diamond coating holds up well!
