It features a multilayer PVD coating combining AlTiN and AlCrN layers for heat and wear resistance during interrupted and continuous cuts. The insert carries a negative rake angle, a neutral hand, and a chamfered and honed cutting edge with a 3\/64-inch corner radius. With 6 available cutting edges and compatibility with KENLOC-style clamp and pin toolholders, it delivers a consistent cost-per-edge value on production turning applications.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning, facing, and boring operations on steel and cast iron workpieces, corresponding to ISO material groups P and K. It performs in both light finishing and moderate roughing scenarios where a maximum depth of cut of 0.050 inches is appropriate. The KENLOC series toolholder system is the intended mounting platform, and the insert is sized to the 433 insert size code with a 1\/2-inch inscribed circle. Machinists and CNC operators in job shops, production facilities, and maintenance machining environments are the primary users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMultilayer PVD coating (AlTiN and AlCrN) for elevated heat resistance and extended tool life on ferrous materials\u003c\/li\u003e\n\u003cli\u003e6 cutting edges per insert for reduced cost per edge on high-volume turning\u003c\/li\u003e\n\u003cli\u003eChamfered and honed cutting edge style reduces chipping risk on interrupted cuts\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation fits left-hand, right-hand, and straight toolholder setups\u003c\/li\u003e\n\u003cli\u003eClamp and pin holding method provides secure seating in KENLOC-style toolholders\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and ISO insert geometry standards for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with KENLOC-series clamp and pin toolholders accepting WNMG433 insert geometry.
