Review on Diamond Baban Coating Ceramics Porcelain by Joshua Castillo

I can recommend it to everyone! Like most people here I was looking for something to drill drainage holes to turn dishes into planters. I have a pack of Black & Decker masonry bits (not hole cutters) that didn't work as I had hoped. This was the most reasonable option I found in terms of bits/cost, so I decided to give it a try. So glad I did. They are much faster than the bits I've used with good size options as needed. I've used the same drill bit to drill a few dozen holes in porcelain, ceramic, and stoneware with no sign of blunting or slowing down. It's a bit difficult for them to get the first "bite", but then everything goes smoothly. They also run faster and cooler than my previous tips (use cut water to keep tips as cool as possible). I like her. I have recommended them everywhere
