    The rigidity of short-length bits without sacrificing reach. The shallow drilling depth makes these less likely to wobble than other bits of the same length, so they stay centered and drill straighter. High-speed steel is good for general purpose drilling in most metals.
    Extended Length—Drill through panels and thick workpieces with our longest bits.
    Black Oxide—The dark finish increases wear resistance and reduces friction to improve chip flow, so these bits can last 50% longer than uncoated bits.

    Our strongest short-flute bits, these have a carbide tip that stays sharp when drilling abrasive materials, such as titanium. The shallow drilling depth makes them less likely to wobble than other bits of the same length, so they stay centered and drill straighter.
    Extended Length—Drill through panels and thick workpieces with our longest bits.

    These bits combine the toughness and wear resistance of cobalt with short flutes for rigidity. The shallow drilling depth makes them less likely to wobble than other bits of the same length, so they stay centered and drill straighter. Cobalt lasts at least twice as long as high-speed steel. It can also run up to 25% faster at higher temperatures without damaging the bit on hard materials such as nickel.
    Extended Length—Drill through panels and thick workpieces with our longest bits.
    Uncoated—Polished to eject chips, these are also known as bright finish bits.
