    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.
    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.
    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.

    Shown with Carbide Inserts

    (Sold Separately)

    When you need to drill dozens or even hundreds of holes, use a bit with replaceable carbide inserts. Once the cutting edges wear down, just change the inserts instead of sharpening or throwing the bit away. The holes in the bit channel coolant through the tool for more efficient chip evacuation. Also known as indexable drill bits.
    Each drill bit requires two inserts—one on the inner cutting edge and one on the outer cutting edge. Replacement inserts are sold separately.

    DeWalt Cordless Hammer Drills

    Image of Product. Front orientation. Drills. DeWalt Cordless Hammer Drills.
    Just twist the collar ring and this tool will change from a standard cordless drill to a hammer drill.
    The rotary-only mode is for general purpose drilling and driving fasteners. Use this mode with standard drill bits for wood and metal as well as masonry drill bits. In rotary-percussion mode, the tool provides both a rotary drilling and hammering action. The hammering action pounds concrete and masonry, which breaks up the material while it drills. Use this mode for drilling masonry materials using carbide-tipped masonry drill bits.
    This drill has a variable speed motor—the further you depress the trigger, the faster the drill rotates. The adjustable clutch lets you adjust the torque.
    See Batteries and Chargers for DeWalt Cordless Tools for replacement batteries and chargers.
    Keyless Chuck—Drills with keyless chuck open and close without a key for fast bit changes.

    DeWalt Cordless Drill/Drivers

    Style A

    A lithium ion (Li-Ion) battery powers these cordless drills, which means they weigh less and have a longer run-time than cordless drills that use nickel cadmium (NiCad) batteries. They have a variable speed motor—the further you depress the trigger, the faster the drill rotates.
    See Batteries and Chargers for DeWalt Cordless Tools for replacement batteries and chargers.
    Keyless Chuck—Drills with keyless chuck open and close without a key for fast bit changes.
