    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.

    Drill Bits for Wood

    Image of Product. Front orientation. Drill Bits. Drill Bits for Wood.
    Make rough holes in wood for jobs such as running wire and pipe through framing studs and sheets. These bits have two sharp edges for faster cuts than fluted bits and won't cause the surface of the material to splinter. A centering point keeps them stable while drilling soft and hard woods such as pine, plywood, and oak. Also known as spade bits.
