Drill through ultra-hard quartzite, granite, and quartz with exceptional speed, maximum durability, and precision-patterned diamond segments.
Drilling faucet holes, anchor paths, and plumbing drop-ins through dense modern slabs can cause slow bit wear and costly stone blowouts. The Core Bit Premium Black Series is engineered specifically for maximum speed and longevity under demanding shop conditions. Featuring premium-grade, precision-patterned diamond segments, these bits deliver a highly aggressive, uniform bite that cuts significantly faster than standard randomized bits. Backed by heavy-duty vacuum-brazed core protection on both the inner and outer barrel, they effortlessly eliminate hole binding and facilitate rapid core plug removal, even when handling severe, hard materials like quartzite.
Advanced Patterned Diamond Segments: High-concentration diamond structures ensure a consistently razor-sharp cutting edge throughout the entire life of the bit, completely eliminating slow drilling drops.
Dual Vacuum-Brazed Core Protection: Lined with rugged, abrasive diamond coatings inside and outside the core barrel. Outer diamonds actively prevent bit binding in deep holes, while inner diamonds ensure effortless core plug removal.
Shatter-Free Quartzite & Dense Stone Performance: Custom-calibrated to easily cut through the most brittle, dense, and difficult materials on the market, including Quartzite, Premium Granite, Engineered Quartz, and Porcelain slabs.
Heavy-Duty High-Speed Engineering: Safely rated to withstand intensive fabrication environments with operational tool speeds up to 10,000 RPM (optimized for excellent wet or dry performance).
Universal 5/8"-11 Threading: Standard industrial 5/8"-11 female thread spins directly onto standard electric or pneumatic right-angle grinders and variable-speed stone polishers without requiring awkward adapters.
