The Venom Gold Dual Diamond Vacuum Brazed Core Drill Bit is designed for Porcelain, Tile, Quartz, Granite, Quartzite and Dekton.

This is a Dual Function core bit that does two jobs in one tool:

• Drills the hole, AND

• Cuts the bevel with the same bit

This eliminates switching tools and saves time, especially on sink drains, faucet holes, shower plumbing openings, and countertop installs.

Use wet or dry depending on your setup.
Attaches with a 5/8-11 female thread for polishers, grinders, and air tools.
