Yes, very good. My brother and Laura really did. I like them works well

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.

I had a nice set of salt and pepper shakers to match heirloom stone china, but they weren't used for years because the holes were too small. I researched videos and saw how some drill bits specialized for drilling ceramic-type materials are available, using water. I was able to enlarge the holes that were already there. Some cracking on the glaze occurred but otherwise it bore through and made a clean larger hole in seconds. I haven't tried some of the shaped bits that came with the set, but will be trying to smooth out some of the chips in older pieces I couldnt bare to throw out. These bits work on drummel tool and regular drills.
