The MK Diamond MK-290 2-1/4-inch (57 mm) core bit is a Premium Grade bit for drilling clean, smooth holes through ceramic tile and marble. A replaceable pilot drill keeps the bit from wandering when you start the hole, and it can be used wet or dry. It is a handy size for plumbing, faucet, soap-dish and fixture penetrations where a clean edge shows in the finished tile.
