Sandvik Coromant 7231500 Turning Insert WNMG431-MF 2220

Product Description

The SANDVIK COROMANT 7231500 is a WNMG431-MF 2220 series turning insert designed for precision metal-cutting operations on CNC lathes and turning centers. This solid carbide insert features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal stability during continuous or interrupted cuts. The insert carries a 0.5000-inch (12.70 mm) inscribed circle, a 1/64-inch corner radius, and an 80-degree trigon shape with a neutral hand orientation. It is intended for machinists and CNC operators working in production turning environments where consistent tool life and surface finish are required.

This insert is optimized for turning stainless steel (ISO material group M) and is suited for both roughing and finishing passes where the MF chip breaker geometry controls chip formation effectively. The T-Max P series is used in external and internal turning applications on modern CNC turning equipment. The clamp and pin holding method ensures secure seating in compatible toolholders. With 6 available cutting edges per insert, it offers extended use across multiple indexing positions before replacement.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for enhanced wear and heat resistance
• 80-degree trigon insert shape (W) with neutral hand orientation
• MF chip breaker geometry optimized for stainless steel and ISO M workpiece materials
• 1/64-inch corner radius for controlled edge sharpness and surface finish
• 6 cutting edges per insert for maximum indexing value
• Clamp and pin insert holding method for rigid, repeatable seating

Compatibility

Designed for use in SANDVIK COROMANT T-Max P series toolholders that accept WNMG style inserts with a clamp and pin holding method. ISO code WNMG 08 04 04-MF 2220 identifies the correct toolholder and insert pocket geometry required.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Always power down and lock out the machine before indexing or replacing inserts. Use the appropriate torque screwdriver or clamping tool specified by the toolholder manufacturer to seat the insert securely — do not overtighten by hand. Inspect the insert pocket and clamping components for wear or debris before seating a new insert.
