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

Short-Length Drill Bits
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.

Short-Length Cobalt Steel Drill Bits
Also known as screw-machine and stub-length bits, these provide maximum rigidity for drilling straighter holes than jobbers'-length drill bits. 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.

Chip-Clearing Cobalt Steel Drill Bits
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.
