    Coolant-Fed Carbide Drill Bits

    The hardest and most wear-resistant bits, these deliver coolant to reduce heat and evacuate chips. They 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 holes in 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.
    Jobbers' Length—These bits have the balance of rigidity and length needed for most applications.
    Maintenance Length—Shorter than jobbers' length, these bits are more rigid for less wobble when drilling hard material. Also known as mechanics’ bits.
    Titanium Aluminum Nitride (TiAlN) Coated—No drill bits last longer. These are the best for high-speed, high-temperature drilling of very hard and abrasive materials, including titanium and fiberglass.

    Harder and more wear resistant than cobalt steel, these carbide bits create an accurate starting place in your workpiece. Cut an indent, then continue drilling with a longer bit. The indent prevents slipping so the final hole is centered and precise. Carbide stays sharp at high temperatures and faster speeds. It can be brittle, however, so these bits require a rigid machine tool holder to prevent breakage and should not be used in hand drilling applications.
    Short Length—The most rigid bits for drilling the straightest holes.
    Titanium Nitride (TiN) Coated—Drill at higher speeds and last longer than uncoated bits, especially on materials like hardened steel, iron, and stainless steel.
    Titanium Aluminum Nitride (TiAlN) Coated—No drill bits last longer. These are the best for high-speed, high-temperature drilling of very hard and abrasive materials, including titanium and fiberglass.
    Uncoated—Excellent for a range of materials but won't last as long as coated bits.
