Cut threads into most metal and plastic.

Often used for thread repair and occasional hand tapping, these carbon steel taps can thread holes in most metal and plastic, but they have a shorter tool life than standard taps.

For start-to-finish tapping of left-hand threads, these sets include one taper-, one plug-, and one bottoming-chamfer tap.

Use a single set for many sizes of internal and external threads. All sets include tap and die wrenches.
