Review on 💎 Diamond Hole Saw for Drilling Porcelain in Bathroom by Antoine Cash

I only used one of these drill bits, I had to drill through a freshly tiled wall to install the TV, it was 1/4 inch thick tile and 1/2 inch cement board . I thought it would hurt but it made it nice and easy. He went through both materials with a spray gun for cooling. Removing the material from the drill probably took the most time. Getting started wasn't a problem. I also had a 1x1 piece in which I drilled a hole just enough for the drill to go where I wanted the top mounting holes to be the top of the wall, then I attached the top of this 1x1 to the ceiling and started with my holes a pilot hole in the wood which also allowed me to have both holes at the same height without having to take a lot of measurements to make sure it was level.
