Kit Includes: This kit contains one High-Speed Steel (HSS) Left Hand Reverse Thread Plug Tap and one matching HSS Left Hand Reverse Thread Round Die, providing a comprehensive solution for threading and rethreading tasks. This Left-Hand Plug Tap and Matching Left-Hand Reverse Round Die set is specifically designed for applications requiring left-hand threading, making it essential for reverse-threaded fasteners, automotive repairs, and machinery components where standard right-hand threads won't work. Made from durable high-speed steel (HSS), the plug tap is perfect for creating or repairing internal threads, whether by hand or with a machine. It works efficiently on most materials and is ideal for both through holes and blind holes. The matching round die is engineered for cutting or rethreading external left-hand threads, offering superior wear resistance and longevity. Designed with a dual-sided chamfer, it provides threading flexibility—one side with a 2 to 3-thread chamfer for standard threading and the other with a 1 to 1-1/2-thread chamfer for threading close to a shoulder. The adjustable die, featuring a fine-pitch screw and beveled slot, allows for precise thread cutting and easy setup in machine holders. Whether for maintenance, repair, or custom fabrication, this left-hand threading set ensures accuracy and durability for specialized applications.
