Carbide-Tipped Drill Bits
 |
Jobbers' Length Round Shank |
 |
Standard |
Performance similar to solid carbide but at a lower price point. Like carbide bits, these are stronger than cobalt and high-speed steel and maintain their sharp edges when drilling abrasive material. However, when drilling tough metals like iron and hardened steel, upgrade to carbide for longer life.
Jobbers' Length—These bits have the balance of rigidity and length needed for most applications.
High-Speed Steel Drill Bits
 |
Jobbers' Length Morse Taper Shank |
|
Standard |
Our basic drill bits are also the most versatile. Cut holes in a variety of metals, from the softest aluminum to the hardest steel.
Jobbers' Length—These bits have the balance of rigidity and length needed for most applications.
Black Oxide—The dark finish increases wear resistance and reduces friction to improve chip flow, so these bits can last 50% longer than uncoated bits.
