About Drill Bits

These jobbers'-length bits 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.

Titanium-nitride (TiN) coated drill bits last longer and can drill at higher speeds than uncoated and oxide-coated drill bits.

Titanium-aluminum-nitride (TiAlN) coated drill bits are the most wear and temperature resistant for the longest life and highest drilling speeds.

Drill bits with a split point keep centered without a pilot hole.

Short-Length Drill Bit Sets

Also known as screw-machine and stub-length bits, these provide maximum rigidity for drilling straighter holes than jobbers'- and maintenance-length drill bits.

Black-oxide drill bits produce less friction than uncoated drill bits.

Drill bits with a split point keep centered without a pilot hole.

Cobalt Steel Drill Bit Sets

These jobbers'-length bits have the rigidity and length required for most applications. Made of cobalt steel, which has better heat and wear resistance than high-speed steel, they can run up to 25% faster and have a longer tool life.

Titanium-nitride (TiN) coated drill bits last longer and can drill at higher speeds than uncoated drill bits.

Drill bits with a split point keep centered without a pilot hole.

Carbide Drill Bit Sets

Carbide

For the highest accuracy and longest tool life, these solid-carbide bits 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 hand-held drilling applications. All are jobbers’ length so they have the rigidity and length required for most applications. A four-facet point keeps the bit centered without a pilot hole.

Uncoated drill bit sets are good for general purpose drilling in most metal and plastic.

Left-Hand Drill Bit Sets

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.
