Sandvik Coromant 7231502 Turning Insert WNMG432-MM

Product Description

The SANDVIK COROMANT 7231502 is a WNMG432-MM 2220 indexable turning insert designed for precision external turning operations on CNC lathes and turning centers. It is manufactured from solid carbide and features a multilayer CVD coating of TiCN, Al2O3, and TiN, which provides thermal resistance and wear protection during cutting. The insert carries a neutral hand orientation, a 1/2-inch inscribed circle, and a 1/32-inch (0.0313-inch) corner radius. With six available cutting edges and a trigon (80-degree included angle) geometry, it delivers efficient material removal rates per edge. It is intended for installation and use by machinists and CNC operators in production turning environments.

This insert is engineered for turning stainless steel (ISO material group M) as its primary workpiece application. The MM chip breaker geometry is suited to medium cutting conditions where chip control on austenitic and similar stainless alloys is a priority. The T-Max P series is a widely used platform for external turning, profiling, and facing on CNC turning centers in both job shop and production settings. The ISO designation for this insert is WNMG 08 04 08-MM 2220, which can be used to cross-reference and identify compatible toolholders.

Key Features

• Multilayer CVD coating: TiCN, Al2O3, and TiN for heat and wear resistance on stainless steel
• Manufacturer grade 2220 optimized for ISO M (stainless steel) workpiece materials
• Trigon insert shape with 80-degree included angle provides a strong cutting edge
• MM chip breaker geometry promotes reliable chip control in medium turning passes
• Six cutting edges per insert maximize cost efficiency per insert
• Compatible with clamp and pin insert holding methods

Compatibility

This insert uses ISO code WNMG 08 04 08-MM 2220 and belongs to the SANDVIK COROMANT T-Max P series. It is compatible with WNMG-style toolholders that accept clamp and pin holding methods. Verify toolholder seat geometry and clamping style against the T-Max P series toolholder specifications before installation.

Installation Notes

Indexable turning inserts are installed and indexed by machinists or CNC operators. Power down and lock out the machine spindle before changing inserts. Use the correct torque wrench for the clamping screw as specified by the toolholder manufacturer — do not overtighten, as this can fracture the carbide. Inspect the insert seat and shim for wear or debris before seating a new insert, and confirm the insert is fully seated before resuming cuts.
