"This has a similar effect on tiles as a hammer & chisel. I purchased this to replace the blade in a tile saw, the old blade made a much nicer finish on the tiles compared to this. It made no difference how slowly or carefully i tried to make each cut the result was the same. Large chips along the entire cut edge of the tiles, this did improve slightly as the blade started to wear. Considering this is meant to be professional quality the result is far from professional."
