Review on 💎 Diamond Genround Hollow Ceramic Porcelain Cutting Tools: Unleashing Precision and Durability by Lamar Vanderburg

bits worked as intended on standard tile but failed on the marble surface I used them on. I'm not sure if it was just due to the hardness of the marble or maybe because they were already used on another surface. For the price I really have nothing to complain about. much better than spending $60 on just one of the sizes!
