Quick-Change Carbide Drill Bits

Uncoated

Make fast bit changes—all of these bits have the same shank diameter, eliminating the need for different collets to hold each size. Made of solid carbide for the highest accuracy and longest tool life, they are harder, stronger, and more wear resistant than high-speed steel, cobalt steel, and carbide-tipped bits. They retain a sharp, hard edge at high temperatures for the best performance on hard and abrasive material. These bits require rigid toolholding to prevent breakage and should not be used in handheld drilling. All are jobbers’ length so they have the rigidity and length required for most applications.

Drill bits with a four-facet point keep centered without a pilot hole.

High-Speed Steel Left-Hand Drill Bits

Uncoated

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.
