High-performance spiral-flute taps are harder and more wear-resistant than general purpose spiral-flute taps. They provide better precision and accuracy than general purpose taps when used for threading holes in designated materials. The taps have spiral flutes that pull chips out and away from the hole as the tap moves into the hole to create threads, which helps prevent chips from packing in the hole. They create internal threads in blind holes and are installed into a toolholder on a machine such as a lathe or CNC machine to operate.
