    Professional Stone Applications

    Designed for granite, marble, quartz, quartzite, engineered stone, and other hard materials, these diamond drill bits deliver the accuracy and durability required by fabrication shops, installers, and monument professionals.

    Choosing the Right Diamond Drill Bit

    Selecting the proper diamond drill bit depends on the size, depth, and type of hole required. Matching the tool to the application improves drilling speed, hole quality, and overall tool life.

    • Blind holes: Choose blind hole drill bits when a flat-bottomed hole with controlled depth is required.
    • Decorative work: Vacuum-brazed carving bits are ideal for shaping, engraving, lettering, and artistic stone fabrication.
    • Large diameter holes: Use Diamond Core Bits for faucet holes, drain openings, and larger cutouts over 1 inch in diameter.
    • Countertop faucet holes: Browse our Wet Diamond Core Bits category for standard faucet and plumbing installations.
    • Best drilling practices: Always use water for cooling, begin drilling at a low RPM, avoid excessive pressure, and use a drill guide whenever possible for accurate hole placement.

    BB Industries supplies professional diamond drill bits trusted throughout the stone fabrication industry for anchor installation, hardware mounting, monument work, CNC machining, and precision countertop fabrication.

    Frequently Asked Questions

    What diamond drill bit do I need for granite?

    For holes smaller than approximately 1 inch in diameter, use a non-coring diamond drill bit. Larger openings such as faucet holes, drain holes, and plumbing penetrations are typically created using diamond core bits. Both require continuous water cooling when drilling granite.

    Can you drill into granite with a regular drill bit?

    No. Standard high-speed steel and carbide drill bits are not designed to cut granite effectively. Diamond drill bits use industrial-grade diamonds bonded to the cutting surface to grind through hard stone materials while maintaining cutting efficiency and tool life.

    How do you drill a hole in granite without cracking it?

    Use a diamond drill bit with continuous water cooling, begin drilling at approximately 500 to 700 RPM, and allow the diamonds to cut without excessive force. Keeping the drill perpendicular with a guide or template helps produce clean, accurate holes while minimizing stress on the stone.

    What is the difference between non-coring bits and core bits?

    Non-coring bits remove all material inside the hole, producing a solid finished hole. Diamond core bits remove only the outer ring of material and leave a removable core or plug behind, making them the preferred choice for larger diameter openings.

    When should diamond drill bits be replaced?

    Diamond drill bits should be replaced when cutting speed slows noticeably, excessive heat develops despite proper water cooling, or the diamond segments become worn. Unlike conventional drill bits, worn diamond cutting surfaces cannot be resharpened.
