    High-Speed Steel Drill Bit Sets

    Our basic drill bits are also the most versatile. Cut holes in a variety of metals, from the softest aluminum to the hardest steel.

    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.
    Gold Oxide—Like black oxide, this finish adds wear resistance and reduces friction for improved chip flow. Because it’s less prone to flaking off, it offers better rust protection when bits aren't in use.
    Titanium Aluminum Nitride (TiAlN) Coated—The hardest and most wear-resistant coating, especially at high temperatures. These bits are best for hard and abrasive materials, such as iron and titanium.
    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.

    Cobalt Steel Drill Bit Sets

    Tough and wear resistant, cobalt steel bits last at least twice as long as high-speed steel. They can also run up to 25% faster at higher temperatures without being damaged on hard materials, such as nickel.

    Carbide-Tipped Drill Bit Sets

    Performance similar to solid carbide but at a lower price point. Like carbide bits, these are stronger than cobalt and high-speed steel and maintain their sharp edges when drilling abrasive material. However, when drilling tough metals like iron and hardened steel, upgrade to carbide for longer life.

    Left-Hand High-Speed Steel Drill Bit Sets

    With flutes that spiral in the opposite direction of other bits, these are primarily used to remove stripped screws. Choose a bit that’s slightly smaller than the diameter of the screw’s head. Set your power tool to rotate in reverse. Slowly drill in the center of the screw head, maintaining constant pressure. As the bit penetrates, it will catch onto the screw and reverse it out of the hole. If the screw is badly stripped, you might need to punch a starter hole. Also known as reverse-flute bits. High-speed steel is the versatile choice for drilling most metals.

    Drill Bit Sets for Wood

    Image of Product. Front orientation. Drill Bits. Drill Bit Sets for Wood.
    Make rough holes in wood for jobs such as running wire and pipe through framing studs and sheets. These bits have two sharp edges for faster cuts than fluted bits and won't cause the surface of the material to splinter. A centering point keeps them stable while drilling soft and hard woods such as pine, plywood, and oak. Also known as spade bits.

    Tap and Drill Bit Sets

    Plastic Case

    Drill and tap a variety of hole sizes. These taps and drill bits are for use on metal and plastic.
    Uncoated Carbon Steel Tap—Uncoated carbon steel taps are for thread repair and occasional tapping.
    Plug Chamfer—Plug-chamfer taps are a versatile choice for most tapping applications. With 3-5 chamfered cutting threads, they require moderate torque and are often used for start-to-finish tapping of through holes and closed-end holes. However, they do not start threads as easily as taper chamfers. When using them to tap closed-end holes, be sure to leave sufficient space at the bottom for chips to accumulate.
    Black-Oxide High-Speed Steel Drill Bit—Black-oxide high-speed steel drill bits have a longer tool life than carbon steel. They cut with less friction than uncoated drill bits.

    Hex-Shank Tap and Drill Bit Sets for Drills and Powered Screwdrivers

    Image of Product. Front orientation. Tap and Drill Bit Sets. Hex-Shank Tap and Drill Bit Sets for Drills and Powered Screwdrivers.
    All taps and drill bits have a hex shank for direct connection to tools such as drills and power screwdrivers. They're made of high-speed steel and are for use on most metal and plastic. Taps have a plug chamfer with 3-5 chamfered cutting threads, so they're suitable for start-to-finish tapping, but they’ll need space at the bottom of closed-end holes for chips to accumulate.
