Effortless Precision in Hard Tile and Stone

The Bosch HDG14 1/4-Inch Diamond Hole Saw is engineered to deliver professional results in the hardest masonry materials. Whether you are installing bathroom fixtures in porcelain, drilling through granite countertops, or working with slate and glass, this tool provides the durability and speed you need. Utilizing advanced vacuum-brazed diamond technology, the grit is fused directly to the steel body, allowing the saw to cut faster and last significantly longer than standard diamond grit bits. This robust construction ensures consistent performance even in the toughest applications.

Designed for efficiency, this hole saw features segmented teeth that effectively reduce heat build-up and clear debris, ensuring a clean cut every time. The bit is compatible with the Bosch Quick Change universal hole saw system, allowing you to swap sizes or types in seconds without losing your rhythm. Optimized for use with wet sawing techniques, this diamond hole saw ensures smooth starts and a superior finish, making it an essential addition to any tiler or remodeler's toolkit.

Pro-Tip: Diamond bits require water to stay cool and maintain their cutting edge. If you don't have a dedicated wet saw, use a spray bottle to keep the cut line wet. To prevent the bit from "skating" on smooth tile, start your drill at a 45-degree angle to create a small notch, then slowly raise the drill to a vertical position to finish the hole.
