Review on Diamond-Genround Hollow Ceramic Porcelain by Roberto Manzer

I bought this machine mainly because of the small size that other brands don't have. The bits are thinner metal than other brands I have. There's also a lot less sparkle, which means fewer diamonds. But what is there to complain about at the price? 06/20/2018 Set another star. I used a 2" saw to make consecutive holes for electrical outlets down the center of a 3/8" ceramic tile. Despite my reservations, the saw went through the tile on the drill without much effort.
