Conquer the Hardest Materials with Confidence.

Drilling into expensive porcelain tile, granite countertops, or dense masonry is a high-stakes job where one slip can ruin the entire piece. The Bosch HDG7 Diamond Hole Saw Set is the professional-grade solution engineered for fast, clean, and crack-free holes in the toughest materials. Featuring innovative technology for no-walk starts and superior cutting speed, this kit gives you the confidence to drill perfect holes, every time.

Key Features & Professional Benefits

• Superior Speed & Longevity: The vacuum-brazed diamond grit is permanently bonded to the cutting edge, providing dramatically faster cuts and a significantly longer life than traditional diamond-coated bits.

• No-Walk, No-Skate Starts: The innovative spring-loaded AutoStart pilot bit ensures your hole starts exactly where you want it, every time. It eliminates dangerous bit ‘walking’ on smooth, hard surfaces, protecting your material and guaranteeing accuracy.

• Cooler, Cleaner Cutting: The segmented teeth are designed to reduce debris buildup and dissipate heat during wet cutting, resulting in cleaner holes and preventing heat fractures in delicate materials like porcelain.

• Fast Tool Swaps: The Quick Change™ universal hole saw system allows you to switch between any size or type of compatible hole saw in seconds, keeping your workflow efficient.

IMPORTANT: For Wet Use Only

For optimal performance, longevity, and safety, these diamond hole saws are designed exclusively for wet cutting. Always use a continuous stream of water to cool the bit and suppress dust. This tool must be used with a drill or machine on a GFCI-protected circuit.
