Review on Enhance Your Crafts with Brccee AC Gemstone Craftsman Engraving Experience by Justin Vasquez

Very good selection of bits, 60 in total with diamond tips. You get 3 of each type and all have 1/8" shanks and come packaged in 3 plastic boxes to store most rotary tools. They fit my tool perfectly and I was impressed with how well they fit for carving and engraving. I have tried them on stone, tile, plastic and some hardwoods and the bits have not dulled at all. These bits can be used with a standard drill and keyless chuck but I think they work best with a higher speed dremel rotary tool. Good Quality and if you are working with very hard materials the bits are inexpensive so it's ok if you break them or wear them down through use I mainly use them to clean 3D printed parts and these bits last forever, if I only use them on PLA and ABS plastic.
