Ceramic Tile Hole Saw is a good choice for faucet, pipe and shower head installations. This hole saw features a durable diamond grit edge, for faster cuts, less dust and less chipping. Designed to fit all common drill chuck sizes. For best drilling, keep cutting surface wet and let the drill bit stay cool by drilling in 3 to 5 second bursts. For harder tiles like Porelain, a porcelain rated hole saw should be used.
