LUO KE13 Pcs T Shape Diamond Burr - 3/32'' Shank Channel Cutting Burs Diamond Mounted Stone Carving Burr for Rotary Tools Includes Dremel

First off you need a keyless chuck if you plan to use these with a dremel as they are smaller then 1/8th. But overall they are great burrs! I didnt think I would use/need all the different sizes but everything from the large to small come in handy! Large ones are great for sanding, and smaller ones for line work and stop cuts when carving!

Great for cutting into stones to make jewelry. Holds up well for the price. Most diamond burs are expensive.

These are quite unique in design. I had no real need for them when I bought them, but they looked like they might be very handy in the right situation. I was right. I used some of the sizes last weekend, and they worked very well.

These bits are miracle workers! My carving has taken a sudden jump forward due to the level of detail I can get with the small, sharp edges. They easily slide through even the toughest grain and leave a smooth finish along the cut. I've put in a number of hours with these and none of them have broken, which is impressive for the price. I'll definitely buy more to have on hand as backups.
