    Taps

    Image of Product. Front orientation. Taps. Taps.
    Cut threads into holes so screws, bolts, and rods fit snugly. Our basic taps have straight flutes that are good for most jobs.
    Carbide—The hardest and most wear-resistant taps. They last 10 times longer than high-speed steel for the best performance on hard and abrasive materials like nickel and fiberglass. Carbide can be brittle, however, so these taps require a rigid machine tool holder to prevent breakage and should not be used for hand tapping.
    Titanium Aluminum Nitride (TiAlN) Coated—No taps last longer. These are the best for high-speed, high-temperature drilling of tough materials such as iron.
    Plug Chamfer—Our go-to chamfer type, these thread both through holes and blind holes. The tapered section is shorter than a taper chamfer and longer than bottoming chamfer. As a result, they're easier to turn than bottoming taps but require more force than taper taps.
    Bottoming Chamfer—Cut all the way to the bottom of blind holes with taps that have the shortest taper. Since these require the most force to turn, they’re often used to finish holes started by taper- or plug-chamfer taps.
    Number of Flutes—Taps with fewer flutes have more space to capture chips, so you won’t have to clear them as often. However, they can be more difficult to keep straight in the hole.

    Spiral Flute for Blind Holes

    Long, gummy strands from soft metals won’t get stuck on the tap or in the hole. With two layers of slippery coating over spiral flutes, these taps prevent chip buildup that can harm the threads and the tap.
    Cobalt Steel—Tough and wear resistant, cobalt taps last twice as long as high-speed steel. They also can run at higher temperatures without damage to their cutting edges.
    Titanium Nitride (TiN) Coated—Run at higher speeds and last twice as long as uncoated taps.
    Spiral Flute for Through Holes—Left-hand flutes push chips ahead of the tap and out of through holes.
    Spiral Flute for Blind Holes—Pull chips back toward the tap so they won't build up in blind holes.
    Plug Chamfer—Our go-to chamfer type. With a longer taper than a bottoming chamfer, they are easier to turn but won't thread as close the bottom of a hole.
    Bottoming Chamfer—These taps have the shortest taper to thread close to the bottom of blind holes. They require the most force to turn, so they’re often used to finish holes started by plug-chamfer taps.

    Thread Mills

    Cut a range of thread sizes with a single tool. These thread mills can also produce both right-hand and left-hand threads. All are made of solid carbide with an aluminum-titanium-nitride (AlTiN) coating, so they have high strength and excellent wear resistance, even when cutting hard and abrasive material. Use them in a CNC machine that allows helical interpolation.
    When used for internal threading, thread mills can create threads of any size equal to or greater than the minimum size listed. They leave space in the hole for chips to fall, and a broken thread mill can fall into the hole without damaging the workpiece.

    Friction Drill Bits for Tapping Sheet Metal

    Image of Product. Front orientation. Friction Drill Bits.
    Friction heat from these bits melts through sheet metal to produce a hole with a raised lip in seconds. The lip is approximately three times the material thickness, providing enough thread engagement to tap directly into thin sheet metal. That eliminates the need for weld nuts, rivet nuts, or other inserts. Because friction drilling displaces material rather than cutting it, there are no chips to clean up. The formed bushing is also stronger than the original sheet. Pair these bits with a friction drill and a collet, sold separately. Use them on a drill press, milling machine, or CNC machine.

    Impact Wrench Tap, Drill Bit, and Reamer Sets

    28 Pieces

    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.
    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.
