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.

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.

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

Also known as screw-machine and stub-length bits, these provide maximum rigidity for drilling straighter holes than standard-length drill bits. Made of carbide-tipped steel, which has better wear resistance than high-speed steel and cobalt steel, they maintain a sharper, harder edge at high temperatures for excellent performance on abrasive material, such as plastic. Because they aren’t as brittle as solid carbide bits, they can be used in less rigid setups, such as a hand-held drill.

The shank has a smaller diameter than the tip, allowing you to drill large holes with machines that have small-capacity chucks. Also known as Silver and Deming bits, they have a 1/2” diameter shank.

Drill bits with flats on shank have three flat sides to prevent the bit from slipping in the drill chuck.

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