Review on 💎 Gemstone Diamond Engraving Jewelry Cutting Tools by BQLZR by Victor Houser

I did a lot of rock drilling and these are by far my favorite hole saws. Before I got them I had a couple of these rocks that I don't think I can pierce, and these little ones go through them with relative ease. I use my cheap Harbor Freight drill press and am excited to go to my shop to see how many bricks I can make. I've only used 3 of the 100 bits that came in and my performance is already way better! Super happy! As these items ship from China, it takes a little longer than expected, but I'm a big subscriber so I'm used to near-instant gratification. I've already ordered more to have on hand in case I ever miss the remaining 97 bits!
