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.

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.

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.

Cobalt Steel Hex-Shank Drill Bits
In addition to resisting heat and wear better than high-speed steel drill bits, these can also run up to 25% faster and have a longer tool life. Insert them into power screwdrivers, impact drivers, and other tools that accept hex shanks. The flat surfaces on the hex shank allow tool chucks to grip these bits more securely than those with a round shank. A split point keeps the bits centered without a pilot hole.

Carbide-Tipped Drill Bits for Hardened Steel
The straight flutes and notched point withstand the heavy pressure necessary to penetrate hard steel. These carbide-tipped bits maintain their sharp edges when drilling abrasive material. Because they aren’t as brittle as solid carbide bits, they can be used in less rigid setups, such as a hand-held drill. They are jobbers' length and have the rigidity and length required for most hand-held drilling and machine tool applications.
