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.
