Tile saw blades, used with a wet saw, are the preferable choice when cutting most floor and wall tile of any decent size. Tile saw blades come in a variety of sizes, and qualities. The general range is, from lowest to highest diamond content. The deeper the diamond-encrusted rim, the higher the diamond content and the longer the diamond blade will last. Most tile saw blades are continuous rim. They have no individual segments, and rely on water to keep them cool during cutting. There are some segmented tile saw blades used in cutting tiles, but they are usually reserved for cutting granite and marble tiles not ceramic or porcelain.
