    Avoid clogs and dissipate heat with cobalt bits that last at least twice as long as high-speed steel. The flutes clear chips to improve coolant flow and prevent damage to the bit and the hole. They also speed up drilling since you don't have to stop to clear the bit manually.
    Jobbers' Length—These bits have the balance of rigidity and length needed for most applications.
    Uncoated—Polished to eject chips, these are also known as bright finish bits.
