    Chip-Clearing Tap Sets

    Image of Product. Front orientation. Taps. Chip-Clearing Tap Sets.
    A range of sizes that remove chips so they don’t ruin the threads or jam the tap. The spiral-point flutes force chips through the hole to prevent buildup and create threads faster than standard taps. Also known as gun taps.
    High-Speed Steel—The most versatile taps resist heat and wear to stay sharp. They’re good for most metals and plastic.
    Uncoated—The economical choice, these won't last as long as coated taps.
    Gold Oxide—The finish increases wear resistance and reduces friction to improve chip flow, so these taps can last 50% longer than uncoated taps.
    Titanium Nitride (TiN) Coated—Run at higher speeds and last twice as long as uncoated taps.
    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.

    Spiral Flute for Blind Holes

    Sharp, angled flutes cut through tough titanium alloys while reducing heat and preventing clogs. These taps draw out chips gradually to create clean threads and protect the tap from jamming or breaking.
    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.
    Black Oxide—The dark finish increases wear resistance and reduces friction to improve chip flow, so these taps can last 50% longer than 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.

    Chip-Clearing Tap and Drill Bit Sets for Through Holes

    Image of Product. Front orientation. Tap and Drill Bit Sets. Chip-Clearing Tap and Drill Bit Sets for Through Holes.
    Also known as gun taps, the taps in these sets have spiral-point flutes that push chips ahead of the tap and out of through holes. Because they don't need to be reversed to prevent buildup, they produce threads more efficiently than standard taps and are suitable for production work. Taps have a square shank for compatibility with tap wrenches and tap holders for drill presses and milling machines. With a plug chamfer, they have 3-5 chamfered cutting threads, so they're suitable for start-to-finish tapping. All taps and drill bits are made of high-speed steel for use on most metal and plastic.

    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.

    Thread mills cut internal UNC, UNEF, UNF, UNJ, or UNS threads, but the threads they create have a fixed pitch.

    Air-Powered Tapping Arms

    Thread through holes faster than electric tapping arms. These arms run at 700 rpm to speed up repetitive tapping tasks, such as threading small holes in steel. They’re also simple to operate—just connect them to your air supply and pull the trigger.
    These arms are faster than a tap wrench and easier to reposition than a drill press. They’re often used alongside CNC machines to handle small tapping jobs, keeping the CNC machine free for other work. You’ll also need tap collets (sold separately).

    Electric Tapping Arms

    Thread blind and through holes across a range of sizes for more versatility than air-powered arms. Use the touchscreen on these arms to set the torque and speed you need for your hole. You can also set an exact depth, which is particularly useful for tapping blind holes. When the depth is reached, the motor stops and reverses the tap out of the hole, so you don’t bottom out and break a tap. Plug these arms into any outlet and get tapping. They’re also quieter than air-powered arms.
    These arms are faster than a tap wrench and easier to reposition than a drill press. They’re often used alongside CNC machines to handle small tapping jobs, keeping the CNC machine free for other work.
    These tapping arms include a full set of tap collets. When the torque gets too high, the collets spin freely instead of forcing the tap to turn and break. They also unlock quickly, so you can swap taps in seconds.
