The Burkit 1/2"-20 UNF Left Hand Tap and Die Set is engineered for precision thread processing and repair. Made with high-speed steel (HSS 6542) for the tap and durable alloy tool steel for the die, this set is built to last. The tap's straight flute design ensures fast chip removal, preventing blockages and speeding up your machining tasks. It's suitable for processing threads in various through holes and shallow blind holes across a range of metals including cast iron, copper, brass, and steel. The die features a secure conical locking hole, ensuring it stays firmly in place on your wrench during use, making external thread repair efficient and reliable.
This set is designed for left-hand threading, offering a specific solution for applications requiring reverse threads. When cutting or repairing threads, it's crucial to use appropriate lubricating oil on the cutting edge. Reversing the die every 1/4 to 1/2 turn facilitates chip discharge through the designated holes, preventing buildup and ensuring a clean thread finish. The recommended feed rates vary by material hardness, with slower speeds advised for harder metals to maintain tool integrity and achieve optimal results.
For Indian workshops, this imported set provides a specialized solution for left-hand threading needs, complementing standard metric or imperial tools. While local alternatives may offer general threading capabilities, this set's specific left-hand UNF configuration ensures compatibility for specialized projects.
