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.

Short-Length Carbide-Tipped Drill Bits

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.
Drill bits with a split point keep centered without a pilot hole.
Drill bits with 135° point angle produce smaller chips than 118° point to prevent clogging.

Hex-Shank Drill Bits

Insert these bits directly into power screwdrivers, impact drivers, and other tools that accept 1/4" hex shanks. A split point keeps the bit centered without a pilot hole.
