    Chip-Clearing Pipe and Conduit Taps for Steel and Stainless Steel

    Made of a high-vanadium alloy, these taps are harder and more wear-resistant than other high-speed steel taps. The widely spaced flutes prevent buildup that can ruin threads and keep pipe and conduit from making strong connections. Also known as interrupted-thread taps.

    2-in-1 Pipe and Conduit Taps

    One tap threads holes in pipe and conduit from start to finish. Begin with the taper-chamfer end, which gradually engages with the material and requires minimal force to turn the tool. Then flip to the bottoming-chamfer end to thread all the way through the hole.

    A range of sizes for adding internal threads to pipe and conduit. These taps can also be used to thread components like manifolds. They have straight flutes that are good for most jobs.
    Carbon Steel—The economical choice for occasional hand tapping. These work on most metals and plastic but will dull more quickly than other taps.

    High-Speed Steel—These taps resist heat and wear to stay sharp.
    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.

    Tap, Die, and Drill Bit Sets

    Image of Product. Front orientation. Tap, Die, and Drill Bit Sets.
    Cut and repair threads and drill holes in many different sizes. Tap and die wrenches are included. The dies are hex shaped for use with conventional wrenches. The taps are made of carbon steel and are recommended for thread repair and occasional tapping.
    Taper Chamfer—Taper chamfer taps have 7-10 chamfered threads at the tip for cutting into the workpiece. They require less torque than other chamfer types, making them a good choice for starting threads and tapping through holes. However, a longer taper means that they cannot thread as close to the bottom of closed-end holes.
    Plug Chamfer—Plug chamfer taps are a versatile choice for most tapping applications. With 3-5 chamfered cutting threads, they require moderate torque and are often used for start-to-finish tapping of through holes and closed-end holes. However, they do not start threads as easily as taper chamfers. When using them to tap closed-end holes, be sure to leave sufficient space at the bottom for chips to accumulate.
