    Start threading a hole with one end of these taps and finish it with the other. The taper-chamfer end gradually engages with the material, reducing the force needed to turn the tool. Flip to the bottoming-chamfer end, which has a shorter tapered section, to thread all the way to bottom of holes. No special holder needed—turn these taps with an open-end wrench, or drive from either end using an L-key or ratchet wrench. Taps have straight flutes that are good for most jobs.
    High-Speed Steel—The most versatile taps resist heat and wear to stay sharp. They’re good for most metals and plastic.

    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.
