Product Overview

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.
  • Ideal for use by bath and kitchen installers and commercial and residential plumbers
  • Reverse spiral thread allows continuous water feed for longer life and increased speed
  • Creates 1/2 in. holes in tile walls and countertops to install accessories like safety grab bars, water supply lines, towel bars, toilet paper dispensers and paper towel holders
  • Hardened alloy steel construction stands up to repeated use and high-heat conditions with proper water cooling
