SUPERIOR PERFORMANCE IN THE HARDEST MASONRY MATERIALS

Drill with confidence through the toughest surfaces using the Bosch HDG212 2-1/2 Inch Diamond Grit Hole Saw. Engineered for professional tile setters, plumbers, and remodelers, this high-performance accessory utilizes advanced vacuum-brazed diamond technology to cut faster and last significantly longer than standard grit saws. It is the ultimate solution for creating clean, precise holes in hard materials such as porcelain, granite, marble, slate, travertine, and reinforced glass. Whether installing plumbing lines or electrical conduit, this saw delivers a chip-free finish in materials where standard bits fail.

Productivity is at the core of the HDG212 design. It features a segmented tooth rim that reduces friction and heat buildup while effectively clearing debris from the cut zone. Compatible with the patented Bosch Quick Change™ Universal Hole Saw System, this cutter allows you to swap sizes or switch between types in seconds without requiring extra tools. The integrated side slots make plug removal quick and easy, minimizing downtime between holes. Note: This tool is optimized for wet sawing applications only and must be used with a GFCI-protected circuit for safety.

Pro-Tip: When cutting hard porcelain or granite, heat is the enemy. Always use a continuous spray of water or build a small putty dam filled with water around the drill site. Start the hole at a 45-degree angle to score the surface, then slowly bring the drill upright. This technique prevents the bit from skating and ensures a clean, professional cut.
