The materials that are most suitable for chipless thread forming by chipless taps include aluminum, brass, copper, lead, stainless steel, carbon steel, lead steel, zinc, etc. Simply put, any metal that produces thread-like chips after cutting is a good material for chipless forming. If the chips are in powder form, the material is too brittle and not suitable for use. Threads processed by chipless taps or general cutting (chip) taps can be used interchangeably if the thread pitch is the same. The two form threads in completely different ways. Chipless taps cause metal to displace, while cutting taps remove metal. Advantages of chipless taps: chipless tapping, strong threads, long tap life, sturdy taps, accurate thread precision, efficient production, fast tapping, suitable for tapping machines without lead screws
