Diamond Grinding Burr Drill Bit Set for Dremel Rotary Tool 20Pcs Diamond Burr Bits with 1/8 Inch Shank Rotary Tool Accessories for Stone Glass Ceramics Carving, Grinding, Polishing, Engraving

Very well made diamond burr set. I used two of the bits to remove grout in tight spaces and to repair a stone floor. They held up beyond my expectations.

I've only used a few of these burrs, but they seem pretty good. I don't expect them to last a long time at this price, but they did what I needed them to do, so no complaints

If you need something finely ground or polished, these are NOT for you. But the several I’ve used so far have worked for my purpose. Seems they’ll hold up pretty well. I’ve used them for wood and plastic

i used these bits to drill out broken bolt extractor from the engine block eventually accomplished the mission on the 3rd bit (2 other were completely used up) for the price I paid it was a good buy

They do the job, possibly one or two little projects well. However, they wear out fast

Thank you, 😊 claude barnes.

I really enjoy these. I bought a dremel with the idea of carving names and addresses into rocks I find on my property as gifts. I bought these bits. I've done 2 projects so far and only used 2 different bits (80% of the work with just 1 bit.) Yes, the bit looks a bit dull compared to one of the new ones I have in the set, but it still cuts very fast. No need to throw it out yet. These are well worth the price.

These were perfect for carving into stone. I tried two other brands and they broke almost immediately. I still have life in the one head I used in this kit.

Used these bits to drill out electrical box connectors in my quartz backsplash. They work well and hold cutting power for a long time.
