    External Threading

    Internal Threading

    Install these inserts into a matching holder to cut external or internal threads on a workpiece. They are compatible with top-notch style threading and grooving systems, which use a highly-rigid clamping design, resulting in a smoother finish and superior tool life. When the edge on one face is dull, flip the insert over. Choose a holder (sold separately) with a shank size that fits your machine and workpiece setup. Larger shanks are more stable, while smaller shanks fit into tighter spaces and allow for finer cuts.

    Acme Thread Taps

    Image of Product. Front orientation. Taps. Acme Thread Taps.
    Create the broad Acme threads found on lead screw nuts, linear actuators, vises, and other moving components. These taps have two sets of chamfered threads: the first for cutting a rough profile and the second for finishing it. They’re only for through holes since the two different threads can damage the workpiece if you reverse the tap. Once done threading, release the tap from the holder and remove it from the other side of the hole. Also known as tandem taps.
    High-Speed Steel—These taps resist heat and wear to stay sharp.

    Acme Thread-Repairing Dies

    Image of Product. Front orientation. Dies. Acme Thread-Repairing Dies.
    Make sure screws travel smoothly in vises, presses, actuators, and other mechanical components. These dies repair damage and clean rust from general purpose (Class G) Acme threads so they engage properly. Don’t risk damaging threads further with an inferior quality die. Our dies are machined in the U.S. to precise dimensions for a perfect thread profile. Turn them with a hex die wrench or a standard adjustable wrench.
    Uncoated High-Speed Steel—The most versatile dies stay sharp, even if you use them every day. They last much longer than carbon steel dies and you won’t have to work as hard to cut threads.

    Trapezoidal Thread Taps

    Image of Product. Front orientation. Taps. Trapezoidal Thread Taps.
    The metric version of Acme thread taps. These cut the broad threads found on lead screw nuts, linear actuators, vises, and other moving components. They have two sets of chamfered threads: the first for cutting a rough profile and the second for finishing it. They’re only for through holes since the two different chamfers can damage the workpiece if you reverse the tap. Once done threading, release the tap from the holder and remove it from the other side of the hole. Also known as tandem taps.
    High-Speed Steel—These taps resist heat and wear to stay sharp.

    Left-Hand Acme Thread Taps

    Image of Product. Front orientation. Taps. Left-Hand Acme Thread Taps.
    Prevent counter-clockwise rotating parts from loosening and spinning off. These taps thread holes to mate with left-hand Acme fasteners that secure components like lead screw nuts and linear actuators. They have two sets of chamfered threads: the first for cutting a rough profile and the second for finishing it. They’re only for through holes since the two different threads can damage the workpiece if you reverse the tap. Once done threading, release the tap from the holder and remove it from the other side of the hole. Also known as tandem taps.
