Tungaloy 6772408 Wnmg 433 Zm T9215 Turning Insert

Product Description

The TUNGALOY 6772408 is a WNMG 433 ZM trigon turning insert manufactured from solid carbide and finished with a multilayer CVD coating of TiCN, Al2O3, and TiN. The T9215 grade targets steel, stainless steel, and cast iron applications at ISO material grades P10 and P20. The insert carries a neutral hand orientation with a negative rake angle of -7 degrees, a honed cutting edge, and a 0.0472-inch corner radius. Six usable cutting edges and compatibility with both clamp and pin holding methods make this a practical choice for production turning environments where insert economy and consistent tool life matter to the machinist or CNC operator.

This insert is suited for general turning, facing, and boring operations on CNC lathes and turning centers in both job-shop and production settings. Primary workpiece materials are steel, stainless steel, and cast iron, placing it firmly in P, M, and K ISO material categories. The ZM chip breaker geometry is designed to manage chip control across a range of depths of cut up to 0.0787 inches, making it appropriate for medium finishing and light roughing passes on ferrous materials.

Compatibility

Designed for WNMG-style toolholders accepting a 433-size trigon insert with clamp or pin retention. Confirmed compatible with steel, stainless steel, and cast iron workpieces per ISO material codes P, M, and K. Meets ANSI and ISO standards for WNMG 433 ZM inserts.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench and manufacturer-specified clamping hardware to seat the insert correctly in the toolholder pocket. Inspect the pocket and seating surface for chips or debris before installing a new cutting edge.
