* These carbide inserts are designed for left hand external threading * Here are some tips for machining threads: * To cut external threads, file the edges of the round rod first and then chamfer it at an angle of 45 degrees * Ensure that when compared to the depth of the thread, the chamfer is bigger * Include a chamfer to external thread end parts; Ensure the starting end of a thread has a flat surface * Also, ensure that it is consistent with the central axis of the thread
