Review on 💎 Diamond Ceramic Porcelain Countertop Technology: Unbeatable Strength and Elegance for Your Kitchen by Thasapon Keitt

I used this hole saw to drill holes in ceramic tile and a concrete backsplash for bathtub surrounds. I was able to cut 5 holes in the tile (3 as test holes) and it looks like there is plenty of diamond left to cut for more. I was concerned that I didn't have a pilot drill, but using water as a lubricant and coolant kept the hole saw from wandering. Ceramic is very hard so I was surprised at how well it worked for my project. I don't know how long this will take and I hope not to find out.
