    Fasten differently sized screws with these sets. They save you the effort of switching three separate bits in and out of a power tool, instead letting you flip between a countersinking drill and a screwdriver bit with a single hand. You can also attach your own countersinking drills and screwdriver bits as long as they have a 1/4” hex shank.
    Countersinking drills have an 82° angle, allowing inch-sized flat- and oval-head screws to sit flush with the surface.

    Torx Bit Sets

    Quick-Change

    Hex Shank

    Get a grip with less slip. The bits in these sets have a six-lobe shape that grips fasteners so they won't slip and damage the drive. Also known as star bits.
    Quick-Change Hex Shank—Lock these bits directly into power tools. They won't wobble as much as bits paired with an adapter, so they are the best choice for high-precision tasks.
    Steel—Best for dry environments, since moisture will cause these bits to rust.

    Torx Plus Bit Sets

    Hex Shank

    With larger lobes, the bits in these sets deliver more torque than Torx bits without slipping and stripping the drive. They have a similar profile to Torx but are not recommended for use with standard Torx screws.
    Hex Shank—Also known as insert bits, these snap into hand tools. If you want to use them with power tools, attach a bit adapter (not included).

    Reamer Sets

    Keep a variety of reamer sizes on hand for finishing holes.
    Adjustable Size, Square Shank
    Image of Product. Front orientation. Reamers. Reamer Sets, Adjustable Size, Square Shank.
    Work on a wide range of hole diameters by keeping a set of adjustable reamers on hand. Each reamer can finish multiple hole sizes by moving the adjustable blades within the diameter range. Convenient for maintenance work, these don't require powered tools. They're often used to make precise size adjustments during installation of bearings and bushings.
    Move the blades by tightening and loosening the two nuts on the reamer. To measure size, adjust blades to a known size (such as a bushing or ring), or measure across two opposite blades with a micrometer. When the blades become worn, they can be reground or replaced.
    Turn these reamers by hand with an adjustable wrench or straight-handle tap wrench (sold separately).
    Angled Blade—These reamers are better than those with straight blades for finishing holes with breaks in the surface, such as a keyway.
    Tool Steel—Typically more economical but less durable than high-speed steel, these are for general purpose reaming.

    Reamer Sets for Taper-Pin Holes

    Used for shaping holes to match the profile of taper pins, these sets include a variety of reamer sizes. Drill a hole that matches the size of the small end of the taper pin you want to install, and then ream to taper and finish the hole.
    Square Shank
    Image of Product. Front orientation. Reamers. Reamer Sets for Taper-Pin Holes, Square Shank.
    Turn these reamers by hand with an adjustable wrench, straight-handle tap wrench, or pin vise (sold separately).
    Straight Flute—The most common flute style, these reamers are suitable for a wide range of applications, but not recommended for holes with a keyway or other breaks in the surface.
    Spiral Flute—Since these reamers clear chips better than straight flutes, they leave holes with a smoother finish. They're better for holes with breaks in the surface, such as a keyway, because they cut continuously across the breaks instead of moving in and out.
    High-Speed Steel—Durable and wear resistant, these are good for general purpose reaming in most materials.
    Left-Hand Spiral—These reamers push chips downward as they cut, so they're often used in through holes.
