    Round-Shank Reamer Drill Bits

    Image of Product. Front orientation. Contains Annotated. Reamer Drill Bits. Round-Shank Reamer Drill Bits.
    Drill and finish holes in a single pass with these dual-purpose tools. The tapered tip gradually pierces your material to reduce friction, and the straight flutes make clean cuts without chipping or peeling the edge of the hole. Made from solid carbide, these reamer drill bits are strong and heat resistant. The flutes stay sharp even when cutting abrasive materials such as carbon fiber, fiberglass, and graphite. Use them in drill presses or other machines—carbide is brittle, and will break if used to drill by hand.

    Impact Wrench Step Reamer Drill Bit Sets

    Image of Product. Side1 orientation. Reamer Drill Bits. Impact Wrench Step Reamer Drill Bit Sets.
    Drill, enlarge, and finish a wide range of hole sizes in seconds with just three bits. Made with an oversized shank and hardened high-speed steel, the bits in these sets are built to handle the high torque of your impact wrench without snapping. A built-in pilot has a stepped tip that bites material immediately, centers the tool, and prevents slipping. The steps on the bit have progressively larger diameters—the deeper you drill, the bigger the hole. Count the steps as you drill to achieve the proper size. Like a reamer, these bits leave a smooth, precise hole at each step. If you’re drilling to the bit’s maximum diameter, a safety collar stops the bit at that size. Since these bits deburr as they cut, they’re often used for thin workpieces, such as sheet metal and plastic panels.
    You’ll need a VersaDrive chuck (sold separately) to install these bits into your impact wrench. You can also get chucks for impact drivers and magnetic-base drills (both sold separately). For jobs that don’t require the torque of an impact tool, you can fit these bits directly into a 1/2" chuck on a standard power drill.

    With everything but the impact wrench, these sets are the fastest way to prepare holes with a hand tool. They include a selection of cutting tools and a chuck that lets you swap them in and out of your impact wrench. Made with hardened steel, the cutting tools are built to handle the high torque of the wrench without snapping, even in hard metals. This also means the bits cut holes two times faster than with a power drill, and the taps thread holes 15 times faster than with a tap wrench. The rapid hammering breaks and clears chips as you work to prevent jams. Since your wrench absorbs kickback, it won’t fight you if a cutting tool snags, reducing wrist strain and fatigue over long jobs.
    The chucks hold any tool with a VersaDrive hex shank—including countersinks and extractors—so just one chuck and wrench handle any cutting task.
    13 Pieces—Includes a range of drill bits, taps, and step reamers. All cutting tools are coated with titanium nitride (TiN) to hold up at higher speeds and last longer than uncoated and oxide-coated bits, especially on tough materials like hardened steel and nickel.
    28 Pieces—Includes drill bits, taps, and step reamers plus reamers for hole alignment, drill taps, and hollow core cutters to further speed up your jobs. Use the drill taps to cut threaded holes in one smooth, continuous pass. The reamers enlarge holes and correct misalignment or overlap. The hollow-core cutters attach directly to your power drill, so you can form burr-free holes without a magnetic-base drill. Unlike drill bits, they cut only on the periphery of the hole and produce a solid slug, so they’re faster and leave a smoother edge. Two additional chucks let you use all these cutting tools with an impact driver and magnetic-base drill, too.
