Carbide Drill Bits for Hardened Steel

Harder, stronger, and more wear resistant than carbide-tipped steel, solid-carbide bits maintain their sharp edges longer. They require rigid toolholding to prevent breakage and should not be used in hand-held drilling applications. The straight flutes withstand the heavy pressure necessary to penetrate hard steel. A four-facet or split point keeps the bit centered without a pilot hole. These bits are short length, also known as screw machine or stub length, which provides maximum rigidity for drilling straighter holes than jobbers'-length drill bits.

High-Speed Steel Left-Hand Drill Bits

Also known as reverse-flute bits, the flutes spiral in the opposite direction of other bits. Use in counterclockwise drilling applications such as removing broken screws. These bits are jobbers' length and have the rigidity and length required for most applications.
Black-oxide and black-and-gold-oxide drill bits produce less friction than uncoated drill bits.
