The diamond drill bit engineered for cordless drills and anchor installations. Weha Dry Magic Hex Head Core Bits are vacuum-brazed non-core diamond drill bits developed for fast, clean drilling in ceramic, porcelain, granite, marble, quartz, engineered stone, landscape stone, and all natural stone. The hex shank fits all standard cordless and electric drills — no grinder required — making these the go-to bit for field installation, anchor drilling, and hardware mounting. Specifications Available sizes: 5/16" (8mm), 3/8" (10mm) Total length: Approximately 3-1/8" (80mm) Hex shaft length: Approximately 1-1/2" (40mm) Recommended RPM: 700–6,000 RPM (adjust based on material and size) Use: Wet or dry Technology: Vacuum Brazed II — Weha's patented diamond bond Hex Head Design The hexagonal shaft fits all standard cordless and electric drill chucks — no angle grinder or 5/8"-11 adapter required. The hex design prevents the bit from spinning in the chuck, ensuring stable, controlled drilling throughout the hole. Ideal for installers and fabricators who need a drill-driver solution for field work. Non-Core Drilling Advantage Unlike standard core bits that leave a plug, these bits drill clean holes without leaving a core. This makes them especially useful for: Anchor holes for countertop clips and brackets Screw and hardware mounting holes Adhesive installations using polyester or epoxy Partial-depth holes where core removal is impractical The result is a clean, chip-free hole without blowouts — critical when working with brittle materials such as porcelain and sintered stone. Vacuum Brazed II Technology Manufactured using Weha's patented Vacuum Brazed II technology — cuts faster and lasts longer than standard vacuum brazed bits. Fully exposed diamond bond delivers aggressive cutting action while maintaining durability across ultra-hard materials.
