Review on Optimum Storage Solution: Diamond Granite Ceramic Materials Storage by Mike Snedeker

My son uses it, one Installing grating in our bathroom. The tile is 1/2 inch thick. The new bits went through the tile like butter, but the bits themselves quickly filled the hole with no hole to push the connector back in. Once the tile completely filled the drill bit we could no longer use the tile for drilling and had to use a different diameter drill bit. If there was a hole to push the tile anchor out of, these drill bits would be 5 stars all round.
