NTK SX9 insert grade for high speed Inconel milling

For the high speed milling of Inconel 706, 713 and 718, as well as ductile cast irons, NTK Cutting Tools has developed its SX9 insert grade, the company's toughest milling grade to date. It is said to offer high speed and feed machining beyond 800 m/min, along with heavier depths of cut than previous ceramic grades. According to NTK, SX9 demonstrates exceptional flank wear resistance that makes it the company's best suited grade for rough machining.

Engineers at NTK have developed a number of insert designations for milling. For instance, round RNGN and RPGN inserts can be used along with square SNGN, SNEN and SNGF inserts, as well as rectangular LNX and APCW geometry inserts for shell, face and end milling cutters. The SX9 can also be utilised in turning toolholders with positive and negative round inserts.
