    High-Speed Steel—The most versatile taps resist heat and wear to stay sharp. They’re good for most metals and plastic.
    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.

    Chip-Clearing Pipe and Conduit Taps

    With widely spaced flutes, chips fall away from the tap and plenty of lubricant flows to the workpiece. These taps prevent buildup that can ruin threads and keep pipe and conduit from making strong connections. Also known as interrupted-thread taps.

    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.
