    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.

    Dust-Collecting Carbide-Tipped Drill Bits for Masonry and Concrete

    Connect these hollow bits to a vacuum system, and they'll suck up dust while drilling. Use them to meet OSHA standards for silica dust exposure when drilling in concrete, brick, and other powdery masonry material. These bits are especially useful for cutting holes for adhesive anchors—you don't need to clean out the hole before installing. They have a titanium nitride (TiN)-coated carbide tip that resists wear and heat to stay sharp.

    SDS-Plus

    Shank

    The slotted shank fits SDS-Plus-drive rotary hammers, which rotate and hammer bits simultaneously to penetrate material. Also known as percussion or impact bits.

    Style B

    Use the rotary-only mode for general purpose drilling and driving fasteners (requires a chuck adapter or a magnetic bit holder). In rotary-percussion mode, the tool provides both a rotary drilling and hammering action. In the percussion-only mode, the tool provides only the hammering action. Use this mode when working with chisels and other masonry tools (see Chisels for Rotary Hammers). All have a variable speed motor—the further you depress the trigger, the faster the drill rotates.
    For SDS-Plus Bit Shanks—Also known as SDS-Drive rotary hammers, these are lightweight and ideal for overhead work and drilling smaller holes. A powerful and durable hammer mechanism lets you drill deeper, larger holes in masonry and concrete in less time than with hammer drills. Use with SDS-Plus drill bits. Note: SDS-Plus and SDS-Max bits are not interchangeable.
    36 Chisel Lock Positions—A chisel lock allows you to choose from 12 or 36 chisel positions to match the angle of many surfaces.
    Built-In Safety Clutch—A built-in safety clutch protects you and the hammer if the bit gets stuck in your material.
