Master the Hardest Materials with the Bosch HDG4 4-Inch Vacuum-Brazed Diamond Hole Saw
Unlock professional-grade performance in masonry and stone applications with the Bosch HDG4 4-Inch Diamond Hole Saw. Engineered with premium vacuum-brazed diamond grit, this cutter is designed to bite through the toughest materials—including porcelain, granite, slate, glass, and ceramic tile—where standard bi-metal saws fail. The vacuum-brazing technology fuses the diamond particles directly to the steel edge, ensuring the grit remains intact during rigorous use, cutting faster and lasting significantly longer than traditional diamond-coated bits.
Built for efficiency, the HDG4 features segmented teeth that actively reduce heat buildup and clear debris, ensuring clean, precise cuts every time. It is fully compatible with the Bosch Quick Change universal hole saw system, allowing you to swap between sizes in seconds without additional tools. Designed for wet sawing applications, this accessory ensures safety and longevity when paired with a GFCI-protected circuit. Whether you are installing plumbing fixtures in granite countertops or running conduit through porcelain tile, this hole saw delivers the durability and speed required for the job.
Note: Mandrel and pilot bit are sold separately.
