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-Flute Extended-Length Drill Bits
The short flutes on these bits provide increased rigidity for drilling straighter holes and the long length lets you access hard-to-reach spots.
Drill bits with a split point keep centered without a pilot hole.

Chip-Clearing Drill Bits
These jobbers'-length bits have the rigidity and length required for most applications. The flutes are designed to lift chips out of the hole, reducing clogging and improving coolant flow.
Parabolic spiral flute drill bits have wider flutes for more efficient chip evacuation than spiral-flute bits.
Black-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 black-oxide drill bits.
Drill bits with a split point keep centered without a pilot hole.

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

Drill Bits for Aluminum, Brass, and Bronze
Because softer metal, like aluminum, brass, and bronze, can clog a bit, the flutes on these bits lift chips out of the hole. Also known as slow-spiral drill bits. They are jobbers' length and have the rigidity and length required for most applications.

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.
