Stone Carving Set Diamond Burr Bits Compatible with Dremel, 20PCS Polishing Kits Rotary Tools Accessories with 1/8’ Shank For Carving, Engraving, Grinding, Stone, Rocks, Jewelry, Glass, Ceramics

Works good for softer stone. Keep the bits well lubricated during use. Clean when done using.

I was trying to do some stone engraving and I ran through the cheap diamond burrs I had. So I bought these. Boy, was I surprised. They are surprisingly durable and chew through sandstone (peppered with other harder minerals) and last FARRRRR longer than other brands. Don't know where they're made and don't care. I'm buying a second batch now as a backup.

I bought these for a project I'm doing on slate. I need different depths and angles and these give me all that. I am experimenting with them every day and pleased everytime. They are sharp, durable, easy to install in my Dremel and they fit great. Definitely recommended from me.

Decent.has some high and low spots..good for the $.

excellent selection of bits. I have been looking for years to find the right tool for manicuring my finger and toe nailsa nd the first one I tried from this set works perfectly. Used with care it trims the nail without abrading the skin.
