    High-Speed Steel—The most versatile taps resist heat and wear to stay sharp. They’re good for most metals and plastic.
    Cobalt Steel—These taps resist higher temperatures and and last twice as long as high-speed steel taps. They thread hard materials such as iron and hardened steel without damaging their cutting edges.
    Carbon Steel—The economical choice for occasional hand tapping. These work on most metals and plastic but will dull more quickly than other taps.
    Uncoated—The economical choice, these won't last as long as coated taps.
    Titanium Nitride (TiN) Coated—Run at higher speeds and last twice as long as uncoated taps.

    Tap and Die Sets

    Image of Product. Front orientation. Tap and Die Sets.
    Use a single set for many sizes of internal and external threads. The taps and dies are for use on most metal and plastic.
    Carbon Steel—Carbon steel taps are for thread repair and occasional tapping.
    High-Speed Steel—High-speed steel taps and dies last longer than carbon steel when used on similar material.
    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.
    Hex—Hex-shaped dies are for thread repair and can be used with conventional wrenches.

    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.

    Long-Reach Pipe and Conduit Taps

    Reach into the deep recesses of your system and bypass obstructions to thread pipe and conduit. These are twice as long as standard taps but with the same shank diameter, so you don’t need a different holder. They have straight flutes that are good for most jobs.

    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.

    Image of Product. Front orientation. Drill Taps. Pipe and Conduit Drill Taps.
    Drill and thread holes for pipe and conduit without switching tools. Made of uncoated high-speed steel, these tools are for use on most metal and plastic. Their right-hand spiral flutes keep chips clear by drawing them back toward the tap and out of the hole. With a square shank, they're compatible with tap wrenches and tap holders for drill presses and milling machines. All have a plug chamfer with 3-5 chamfered cutting threads, so they're suitable for start-to-finish tapping of through holes.

    Left-Hand Pipe and Conduit Taps

    Left-hand threads make it easier to disconnect or join sections of pipe. Similar to using a union fitting, you don’t need to rotate the whole pipe to make changes. These taps have straight flutes that are good for most jobs.
