High-Speed Steel Drill Bits
 |
Short Length Round Shank |
 |
Split |
Our basic drill bits are also the most versatile. Cut holes in a variety of metals, from the softest aluminum to the hardest steel.
Short Length—The most rigid bits for drilling the straightest holes.
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.
Titanium Nitride (TiN) Coated—Drill at higher speeds and last longer than uncoated and oxide-coated bits, especially on tough materials like hardened steel and nickel.

Cobalt Steel Drill Bits
Carbide-Tipped Drill Bits

Short 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.
Short Length—The most rigid bits for drilling the straightest holes.
