Chip-Free Thread-Forming Taps

Chip-Free Thread-Forming Taps. Chip-free taps produce cleaner, stronger, and more accurate threads than taps that cut threads. Also called thread-forming taps, they press against the sides of a hole to form threads as they are rotated into the hole. They don't produce chips, which eliminates the need to clear chips from the hole and prevents
