Short-Length Drill Bits

Black Oxide

Titanium Nitride (TiN) Coated

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.

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

Titanium Nitride (TiN) Coated

Titanium Aluminum Nitride (TiAlN) Coated

Gold Oxide

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.

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

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

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

Chip-Clearing Cobalt Steel Drill Bits

Uncoated

The parabolic spiral flutes lift chips out of the hole, reducing clogging and improving coolant flow. With better heat and wear resistance than high-speed steel, these cobalt steel bits can run up to 25% faster and have a longer tool life. All are jobbers’ length so they have the rigidity and length required for most applications. A split point keeps the bit 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.
