These jobbers'-length bits have the rigidity and length required for most applications. 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.
