Yakamoz 30Pcs 2.35mm Shank Titanium-Coated Diamond Burrs Set Rotary File Burs Accessories Kit for Rotary Grinder Tools Grinding Polishing Carving Stone Jewelry Glass Ceramics

This burrs perform as described. They do the job, I have been carving wood, etching glass and carving clam/sea shells. With the assortment of burrs that are in this package, you can do broad work of fine work.I highly recommend this set.

The bits aren't bad, they do what I need them to. They work with the Chicago electric rotary tool, however they don't fit in my Dremel Stylo and I dont have an adapter for them. My biggest frustration is that the case doesn't stay shut, nor do the bits stay in their spot in the case. Overall, not bad for the price.

Small like I needed. Used to cut through 3 mm fused glass pieces. Used under water with medium pressure and had no problems with breakage. I’ve purchased others like this before also with no problems. Good value for the price.

These little burs are not your typical cheaply made bits that arent balanced or round. They are made out of some high quality alloy, don't rust or wear out easily. And the assortment of pear, cone, ball, and cylinder shaped heads is perfect. These are quality enough you can use them on Teeth

The shapes and sizes of these rotary files is just what I needed to clean up corroded sockets in automotive and RV electrical connectors. This gives me tremendous versatility in the types of small connector problems I have.

Great for beginners and sharper than anticipated

I'll start with yes, I know these are cheap and not the best quality but I'd expect at least a little effort here...These arrive in a basic plastic case, which would be fine if it actually closed. It does not stay closed. At. All. There was no type of seal to keep this thing closed either. A piece of tape would have been nice for shipping. Won't be able to store them in this case since it isn't secure.Most likely because of this bad packaging job, we're missing 2 out of the pack. They even look a little like they might have been previously used but this could also just be due to the fact that they're cheap. You get what you pay for (except I paid for a 30-piece and got 28), and for our current need, cheap was fine. If they actually work, they can keep the 3 stars. Will update if they do not.

For the price point and for what I was needing these for functionality was great and durability was alright for price,they look and got great with easy to use and great with high speed, fit Wonderful in my new tool

Good

Works for metal engraving
