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.

Cut a range of thread sizes with a single tool. These thread mills can also produce both right-hand and left-hand threads.

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