Sandvik Coromant 5756653 Turning Insert WNMG431WF 1515

Product Description

The SANDVIK COROMANT 5756653 is a WNMG431WF 1515 grade solid carbide turning insert from the T-Max P series, designed for precision external turning operations on CNC lathes and turning centers. The insert features a multilayer MTCVD coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal stability across a broad range of cutting conditions. With a neutral hand orientation, an 80-degree trigon shape, and a WF chip breaker geometry, this insert is suited for finishing and semi-finishing cuts in steel and stainless steel workpiece materials. It offers 6 cutting edges per insert, delivering consistent performance and cost efficiency in production environments. Machinists and CNC programmers specify this insert for its predictable tool life and chip control in demanding turning applications.

This insert is intended for turning operations on steel (ISO P) as the primary workpiece material and stainless steel (ISO M) as a secondary workpiece material. The WF chip breaker geometry supports light to moderate depths of cut, making it well suited for finishing passes requiring tight tolerances and good surface finish. The T-Max P series is a general-purpose turning platform commonly used in production machining environments, both in job shops and high-volume manufacturing. Installation is performed by qualified machinists or CNC setup technicians working with indexable tooling systems that accept WNMG-style inserts secured by clamp or pin holding methods.

Key Features

• MTCVD multilayer coating: TiCN, Al2O3, and TiN for extended wear resistance and thermal protection
• WF chip breaker geometry optimized for finishing and semi-finishing in steel and stainless steel
• 6 cutting edges per insert for maximum index utilization and cost efficiency
• Neutral hand orientation for use in standard right-hand and left-hand toolholders
• Clamp and pin holding method compatible for secure seating in T-Max P toolholders
• Maximum depth of cut of 0.3264 inches (8.29 mm) supports a range of finishing to light roughing passes

Compatibility

Designed as an OEM-style replacement or direct-specification insert for indexable turning toolholders accepting WNMG-style inserts with a 0.5000-inch inscribed circle and clamp or pin clamping. ISO code WNMG080404WF 1515 can be used to cross-reference compatible toolholder systems.

Installation Notes

Indexable turning inserts are installed and indexed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torx or hex key specified by the toolholder manufacturer to secure the clamping screw to the recommended seating torque for the toolholder — do not over-torque the clamp screw, as this can damage the insert seat or chip the cutting edge. Inspect the insert pocket and seating surfaces for chips or debris before installing a new insert edge.
