    Our hardest reduced-shank bits, these stay sharp at high temperatures and faster speeds. The shank is smaller than the cutting tip to make large holes with drill presses and portable drills that have a standard-size chuck. They offer the best performance on hard and abrasive materials, such as titanium. Also known as Silver and Deming bits.
    Jobbers' Length—These bits have the balance of rigidity and length needed for most applications.
