Long Stone Carving Set Diamond Burr Bits Compatible with Dremel, 8PCS Polishing Kits Rotary Tools 100MM Length Cone Accessories with 1/8" Shank for Carving, Engraving, Grinding, Stone, Rocks, Jewelry

The diamond burr tools worked well to enlarge a ceramic thermocouple shield to fit a larger thermocouple element. And it fit nicely in the Dremel clone purchased at Harbor Freight. Overall, it did the job perfectly.

Muy duraderas recomendadas

These did not handle ANY degree of off center. Maybe it was just a worn collet or user error, but see attached photos of what happened when I turned my Dremel on on the lowest setting. The top was the very first attempt and a bit startling to be honest. The next 3 were attempts were with more caution and I managed to get about 10-20 seconds of use. The thinner ones I was able to successfully use. I needed the long shank to get into a small teapot to grind out some glaze that had blocked the holes.

Definitely great for carving rocks, these bits work well on glass,too.... No good for wood or steel, that's ok,I carve rocks ;) Lasts a lot longer wet cutting,but I can't see,so dry cuts it is.... See it on fb at CRVDROKLLC ,like and follow

Did not use because the shafts are rusting. Poor quality

Good set of bits to carve with.

These r lovely to have for ur collection of burrs

See above. They worked until they didn’t.
