    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.

    With flutes that lift chips out of the hole, you don't have to stop drilling to clear these bits manually. They improve coolant flow to dissipate heat and prevent clogs that can damage the bit and ruin the hole. High-speed steel is good for general purpose drilling in most metals.
    Parabolic Flute—A U-shaped groove on the flutes cuts faster and clears chips more quickly than high-helix bits, so these are better for drilling deeper holes.
    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.

    High-Speed Steel Drill Bits for Plastic

    The precision-ground, 60° point penetrates gradually to prevent cracking and chipping. It also reduces heat that can deform the material. Use these bits for drilling into acrylic, laminate, and other plastics. They're made of wear-resistant high-speed steel.
