Review on Type】Mgtgbao Concrete Masonry Carbide Plastic Cutting Tools for Industrial Drill Bits by Marco Gavi

I've had to drill 6mm holes in some of the large porcelain tiles I'm remodeling in our bathroom to attach a few things through the tile to the subfloor. These beats were perfect for that. I've looked at a few videos online and most of them seemed to say that this type of bit is less likely to crack a tile than the type of bit that looks like metal bits and has twisted grooves running the length of the bit. I can later attest to 9 holes through porcelain stoneware and I have not one single crack to complain about. I ran the drill over the tile and kept a damp sponge handy, adding water every few seconds to keep the tile and drill bit lubricated. Too much time. I don't really know how many holes can be drilled with one drill, but I left about two holes per drill. I have included a picture of a test hole I drilled in a replacement tile and then a picture of a toilet flange installed on the tile because I was able to drill through the tile cleanly. I highly recommend them for any small holes that need to be drilled in tiles.
