Flawless Wet Cutting Precision – Industrial Diamond Hole Saw for Porcelain Tile and Natural Stone

Achieve clean, perfectly round, chip-free holes in the hardest masonry surfaces with the Bosch HDG3 3-Inch Diamond Hole Saw. Specifically engineered for professional tile installers, bathroom remodelers, and stone fabricators, this industrial-grade core drill bit makes fast and easy starts an absolute certainty—even on notoriously stubborn materials like porcelain, granite, marble, slate, and dense ceramic. Designed exclusively for wet cutting applications on a GFCI-protected circuit, this premium masonry accessory delivers smooth material penetration and unmatched speed, making it an indispensable asset when running plumbing lines, shower valves, drainage pipes, or electrical conduits through high-end stone finishes.

This heavy-duty core bit features state-of-the-art vacuum-brazed diamond grit technology along its cutting rim, providing exceptionally sharp cutting action that cuts significantly faster and outlasts standard carbide alternatives. The advanced segmented teeth layout works dynamically to reduce operating heat buildup while rapidly flushing away thick slurry and abrasive debris during heavy use. Integrated seamlessly with Bosch's Quick Change universal hole saw system, this core drill bit snaps onto your mandatory arbor adapter in seconds, completely eliminating tedious hand-tool tightening. Complete with a 1.5-inch maximum drilling depth capacity and compatibility with standard 3/8-inch or larger power drill chucks, this high-performance diamond bit features optimized side slots that allow you to eject dense material plugs quickly and effortlessly.

Key Features

• Vacuum-Brazed Diamond Grit: Premium industrial diamond particles are fused under high temperatures to deliver lightning-fast cutting and extended tool life.
• Engineered Segmented Teeth: Displaces slurry and curtails thermal expansion, allowing the bit to run cooler during demanding deep-bore cycles.
• Quick Change Universal Interface: Compatible with rapid-release mandrels to switch sizes or styles in seconds without requiring extra hand keys.
• Effortless Plug Removal Design: Features side slot windows built into the steel cup body to allow immediate levering and extraction of stubborn material plugs.
• Heavy-Duty Masonry Versatility: Ideal for drilling clean holes in fine porcelain tile, granite countertops, marble slabs, quartz, and heavy natural stone.
• 3/8-Inch Chuck Compatibility: Standard shaft geometry mounts securely into ordinary handheld power drills or robust commercial drill presses.

What's Included

• 1 × Bosch 3-Inch Diamond Quick-Change Hole Saw Core Bit (HDG3)

💡 PRO-TIP: To prevent the bit from walking on smooth, glazed porcelain tile faces, never start drilling flat. Approach the stone surface at a 45-degree angle with the power tool running at medium speed to establish an initial crescent groove, then slowly rock the drill perpendicular to finish the hole while maintaining a steady flow of water to protect the diamond edge!
