    Carbide-Tipped Drill Bits for Masonry and Concrete

    Crush rather than cut material so bits don’t jam or overheat while drilling masonry and concrete. The ultra-hard carbide tip breaks masonry into pieces and the widely spaced flutes channel them out of the hole. These bits stay sharp, resisting wear and heat that will dull or break other bits.

    SDS-Max

    Shank

    The slotted shank is compatible with SDS-Max-drive rotary hammers. These bits use simultaneous rotary and hammering action to penetrate material. Also known as percussion or impact bits.

    Extended Length

    Round Shank

    Standard

    Channel coolant through the holes to reduce heat and evacuate chips more efficiently than other bits. These are designed for CNC machines that supply coolant through the spindle rather than an external source, such as a hose and nozzle. Coolant flows directly from the bit's tip onto the drilling surface. This speeds up cuts and leads to excellent performance in deep holes and tough materials such as stainless steel and titanium. A lower-price alternative to solid carbide, they stay sharp when drilling abrasive material but won’t last as long.
    Extended Length—Also known as gun drills, drill through panels and thick workpieces with our longest bits. Their length is good for creating deep holes but makes them less rigid than other bits. As a result, they are more prone to wobbling or breaking, especially when drilling hard materials.

    Carbide-Tipped Core Drill Bits for Masonry and Concrete

    Remove a core of material with these hollow bits to make larger holes than fluted masonry bits. They're often used for installing pipe and conduit through brick and concrete. The carbide tip resists wear and heat to stay sharp.
