SRA. Crafting stone change dishes, & trashing brand-new Amazon Dremel bits, BAD review for sure

Granted, the bad grinder wheels may be just a bad batch, I want to give a little leeway here because the product has so many good reviews already online, but obviously, either this was a really bad batch, or the selling description needs to be made clear, that they are not for hard stone. Even still, I got these bowls aka change dishes ready, and posted to the Shelbyville Rockhounds Anonymous - shop https://www.facebook.com/profile.php?...
