Product Description
DSDG Dry Granite Drill Bits are sintered diamond core drill bits for dry drilling on granite, hard stone and construction materials. They are suitable for professional stone fabrication, countertop installation and job-site drilling work.
Designed for ultimate versatility, this drill bit works seamlessly in dry mode with high-speed grinders and low-speed polishers alike, and features universal 5/8"-11 thread options for direct tool attachment—no complicated adapters needed (adapters available for 3-jaw chucks). The brazed diamond side protection ensures smooth, scratch-free hole sidewalls and prevents core bit wear, while the sintered segmented design maximizes cutting efficiency and heat dissipation. Whether you’re drilling countertop fixture holes, plumbing openings or construction-grade granite, this is the ultimate professional tool for fast, reliable, cost-effective results.
