Tungaloy 6772332 Tnmg 432 Tm Carbide Turning Insert

Product Description

The TUNGALOY 6772332 is a TNMG 432 TM carbide turning insert in grade T9215, designed for external and internal metal cutting operations including turning, facing, and boring. It features a 60-degree triangle shape with a negative rake angle of -6 degrees and a multilayer CVD coating consisting of TiCN, Al2O3, and TiN applied in sequence for wear resistance and thermal stability. The insert measures 22.00 mm (0.866 inches) in length with an inscribed circle of 0.5 inches and a corner radius of 0.0315 inches. Installation is performed by licensed machinists and CNC operators in production and job shop environments.

This insert is suited for machining steel, stainless steel, and cast iron in turning center and lathe applications. It carries ISO material codes P, M, and K, with material grades P10 and P20, making it appropriate for medium to light roughing and finishing passes. The TM chip breaker geometry is optimized for controlled chip formation across these workpiece categories. It is held in place by clamp and pin, conforming to both ANSI and ISO standards for insert geometry and tolerance class M.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer to secure the insert without over-tightening. Inspect the insert seat and chip breaker pocket for debris before seating a new insert.
