Engineered with a welded-diamond tip, this bit bores through dense, abrasive materials including glazed porcelain and ceramic with ease. The reverse-spiral threads allow for continuous water cooling and efficient debris removal, ensuring fast, clean, and precise drilling.

• Precision drilling: Creates clean 1/2 in. holes in tile walls and countertops for installing grab bars, towel rings, and water supply lines.
• Advanced cooling: Reverse spiral threads allow for continuous water feed, increasing bit life and drilling speed.
• Efficient debris removal: Features a core-ejection slot that makes plugged material easily removable for repeated, uninterrupted cuts.
• Durable construction: Hardened alloy steel and a welded-diamond tip withstand high-heat conditions and repeated professional use.
• Versatile application: Ideal for bath and kitchen installers, as well as commercial and residential plumbers.
