XL version of the unique, patent-pending impact die system for quickly and easily creating and repairing external threads.

• Create or extend heavy-duty threads on thick metal bar
• Repair existing damaged/deformed threads
• Clean old threads clogged with surface coatings, rust or other unwanted material that can prevent threads mating and turning properly

The guide collar system ensures that the thread cutting process runs straight and true. Once a thread is established, the flush type collar can be used.
