Proudly made in the U.S.A.:
Utilizing 8620 alloy steel for its high tensile strength to withstand strong centrifugal force, high load force, high feed rate, and difficult-to-machine material in the era of current CNC machining environment. As the forces exponentially increase, precision and strength in machining and tooling requires a higher quality of the retention knob or pull stud connecting the spindle to the tool holder. To maintain the tight tolerance of critical dimensions on a retention knob, they inspect their parts throughout the manufacturing process. They utilize batch production so that each retention knob has written inspection data and traceability to each batch. Additionally, the threads on their retention knobs are cut, which provides higher strength and excellent thread quality. Each retention knob is carburized to 58-62 RC.
