Install a safety grab bar or towel ring on your tiled wall with the aid of a DEWALT 1/2 in. Diamond Drill Bit. The welded-diamond tip is designed to bore through abrasive， dense tiles， including glazed porcelain and ceramic in addition to rock-hard， solid-body porcelain. It operates at high speeds courtesy of reverse-spiral threads that allow continuous water cooling so you can complete drilling work quickly and cleanly. Plugged material is easily removable from the core-ejection slot so you can make repeated cuts without slowing down.
