    "directAnswer": "Diamond tile core bits are engineered specifically for chip-free hole drilling in delicate, high-density materials like vitreous porcelain, ceramic tile, marble, granite countertops, and glass mosaic. Using vacuum-brazed synthetic diamond technology and internal cooling wax reservoirs, these bits drill cleanly at high RPM (up to 10,000 RPM on angle grinders) without causing cracking, blowouts, or micro-fractures. Available in standard plumbing and electrical diameters from 3/16 inch (5mm) up to 5 inches (125mm) with standard 5/8\"-11 threads and hex drill shank adapters. Call (661) 592-1022 for wholesale volume pricing and same-day will-call.",

    "section2Text1": "Unlike heavy segmented concrete core bits that pound through aggregate, tile core drill bits use premium vacuum-brazed industrial diamonds fused directly to a high-tensile steel tube. This exposed diamond edge grinds vitreous porcelain and glass smoothly at microscopic tolerances, eliminating the perimeter chipping and backside blowout common with traditional electroplated or carbide drill bits.",
    "section2Text2": "Smaller diameters (3/16\" to 1/2\") feature internal paraffin cooling wax that melts during dry drilling to lubricate and cool the cutting edge automatically. Larger diameters (3/4\" to 5\") feature side cooling slots that eject tile slugs and dissipate friction heat during high-speed angle grinder or rotary drill operation. They can be run dry on high-speed angle grinders (5/8\"-11 thread) or wet with water on variable-speed core drills for extended tool life.",

    "faqs": [
      {
        "q": "How do you start drilling a hole in porcelain tile without a pilot bit?",
        "a": "Start drilling at a 45-degree angle to create an initial crescent-shaped groove in the tile surface. Once the diamond rim bites into the tile, slowly oscillate and bring the drill/grinder perpendicular (90 degrees) while applying gentle pressure and rotating in a slight circular motion to clear slurry."

        "a": "Our vacuum-brazed tile core bits are engineered for high-speed dry drilling on angle grinders (up to 10,000 RPM) and feature internal cooling wax in smaller sizes. However, adding water or dipping the bit in a sponge during drilling will further extend the bit's lifespan and virtually eliminate airborne dust."

        "a": "Standard bathroom sink and faucet valves typically require a 1-3/8\" (35mm) hole. Showerhead supply elbows and tub spouts commonly use 1-1/4\" (32mm) or 1-1/2\" (38mm) holes, while toilet drain flanges require 4\" (100mm) holes."
