Our shortest high-speed steel bits, these are the most rigid for drilling the straightest holes. They're also good for tight spaces where longer bits can't fit. Also known as screw-machine and stub-length bits.

Drill through walls and thick workpieces with our longest high-speed steel bits. Their length is good for creating deep holes but makes them less rigid than other bits. As a result, they are more prone to wobbling or breaking, especially when drilling hard materials.

The toughness and wear resistance of cobalt steel in a length that's rigid enough for most applications. Cobalt lasts at least twice as long as high-speed steel. It can also run up to 25% faster at higher temperatures without damaging the bit on hard materials such as nickel.

Drill through walls and thick workpieces and make deep holes with the longest bits made of tough and wear-resistant cobalt. They last at least twice as long as high-speed steel and can run up to 25% faster and at higher temperatures without damaging the bit or material. The length makes them less rigid than other bits, however, so they are more prone to wobbling or breaking, especially when drilling hard materials.

Our shortest and most rigid bits, these offer the performance of solid carbide at a lower price point. Like carbide bits, they are stronger than cobalt and high-speed steel to maintain their sharp edges when drilling abrasive material. However, when drilling tough metals like cast iron and hardened steel, upgrade to carbide for longer life.
