    Designed for soft metals that can gum up other drill bits, wide flutes lift chips out of the hole. This prevents clogs that can weaken and damage the bit and ruin the hole. Also known as slow spiral bits, these are made of versatile high-speed steel.
    Jobbers' Length—These bits have the balance of rigidity and length needed for most applications.
    Uncoated—The most economical option, uncoated bits perform best when used on low-carbon steel and aluminum. Polished to reduce friction, they're also known as bright finish bits.
