Hereafter, all the threads are 11 TPI and the root’s radius 0.32. The same tool for R1½ is recommended. The same tool for Rc1½ is recommended. 1) The largest size of minimum diameter toolholder is recommended for internal threading toolholders. Therefore it is available if minimum diameter is smaller than recommended toolholders. (e.g.) SINR2420S-16 (Min. Bore Dia.: φ24mm) is recommended for the Tool of G7/8 Internal Threading from the above Table, but SINR2016S-16 can also be used. 2) When using "Partial Profile" for Tapered Pipe threading, thread's corners become sharp edged, and the shape will not be the same as the standard shape for Tapered Pipe.
