Sandvik Coromant 5756535 WNMG432-KM 3210 Turning Insert

Product Description

The SANDVIK COROMANT 5756535 is a solid carbide turning insert in the WNMG432-KM 3210 designation, engineered for precision metal cutting in CNC turning applications. It features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN that provides wear resistance and thermal protection during continuous and interrupted cuts. The insert measures 0.3105 inches in length with a 0.5 inch inscribed circle diameter and a 1/32 inch (0.0313 inch) corner radius. Grade 3210 is optimized for cast iron and hard workpiece materials. This insert is installed by machinists and CNC operators in production turning environments.

This turning insert belongs to the T-Max P series and is suited for external turning, profiling, and finishing operations in ISO material group K, primarily cast iron. The trigon (80-degree included angle) insert shape offers six usable cutting edges per insert, reducing tooling cost per part. The KM chip breaker geometry manages chip flow effectively at moderate to high feeds. Neutral hand orientation makes it compatible with standard WNMG-style toolholders used in both roughing and finishing setups.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for extended tool life in cast iron cutting
• Six cutting edges per insert due to trigon (W) insert shape, maximizing value per unit
• KM chip breaker geometry designed for controlled chip evacuation at moderate to high feeds
• 0.0313 inch corner radius suitable for profiling and semi-finishing passes
• Neutral hand insert compatible with clamp and pin style WNMG toolholders
• ISO code WNMG 08 04 08-KM 3210 for direct cross-reference and replacement ordering

Compatibility

Designed for use in WNMG-style toolholders that accept clamp and pin insert holding methods with a clearance code N and tolerance code M. Primary target workpiece material is cast iron (ISO material code K). ISO insert code WNMG 08 04 08-KM 3210 can be used for cross-reference with compatible toolholder systems.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before seating or replacing inserts. Use the correct torque wrench and manufacturer-specified clamp screw to secure the insert - do not overtighten by hand or with non-calibrated tools. Inspect the insert pocket and seating surface for chips or debris before installing a new edge to ensure proper seating and dimensional accuracy.
