Review on 🔧 Stone Carving Set Polishing Rotary Tools: Diamond Burr Accessories for Stone, Rocks, Jewelry, Glass, Ceramics - Perfect for Engraving and Carving with Rotary Tools by Eric Surabhi

Excellent value for money compared to phenolic or nova bits. The container was a bit odd, I have fat fingers, came in a blue cut box with a translucent lid. The bits were divided into three sections, it's hard to get one out without taking them all out first. No big deal. Great product, you have to use the whole bait by turning it back and forth to carry the bait evenly or if you only use the outermost half the back end will be grainier and less used but that can also have a nice side benefit to have . You can end up with a fine, but obviously not much if you do. I didn't have a breakdown or anything like that. I use them on fire agate which is 2 points less hard than diamond on the Mohs scale. Very satisfied. Use a drip irrigation system. Note: Some Dremel, I have a 4000, require you to fully open the nut without removing it - to insert part of the bit. I wanted to buy another keyless chuck and didn't need it. The guy showed me this trick.
