UNF left-hand HSS-G dies are precision tools designed for external threading with a UNF pitch in a counterclockwise direction. Made from high-speed steel, they ensure good wear resistance during cutting operations on metals. These tools are suitable for applications requiring left-hand threading, typical in specific mechanical and assembly sectors. The tooth geometry is designed to ensure smooth cutting and effective chip evacuation, helping to maintain thread quality and tool life. Suitable for use on manual lathes or machine tools, HSS-G dies allow for precise and consistent threads on ferrous materials and metal alloys compatible with high-speed steel.
