It carries the NPGR51 style designation with a KC850 manufacturer grade applied via CVD coating process. The insert features a left-hand cut orientation, a positive rake angle of 10 degrees, and a relief angle of 8 degrees. With a corner radius of 0.0156 inches and an inscribed circle of 0.25 inches, it is built for controlled, repeatable profiling passes in demanding production environments. Licensed machinists and CNC turning specialists are the primary installers.\u003c\/p\u003e\u003cp\u003eThis insert is suited for profiling and turning applications in both residential-scale job shops and high-volume commercial machining cells. It performs on steel and stainless steel workpieces, corresponding to ISO material codes P and M, and material grades P30, P40, M30, and M40. The parallelogram shape and two cutting edges allow efficient use in tight-clearance profiling passes. It is held in place by a clamp-style insert holding method, consistent with standard Top Notch toolholders.
