What it does: Cuts internal (taps) or external (dies) threads on fasteners and pipes.
Key Features:

• Thread rolling machines deform metal for stronger threads

• CNC thread mills create custom pitches

• Pipe threading prevents leaks in plumbing systems
  Why it matters: Without threads, everything from lightbulbs to oil rigs would fall apart!

Fun Fact: The first screw-cutting lathe was invented in 1568.
