Sandvik Coromant 5756486 Turning Insert WNMG432-MF 1125

Product Description

The SANDVIK COROMANT 5756486 is a WNMG432-MF 1125 series turning insert designed for indexable tooling systems used in CNC and manual turning operations. Built from solid carbide with a TiAlN and AlCr2O3 dual-layer coating applied via PVD process, this insert delivers wear resistance and thermal stability when cutting difficult materials. The neutral-hand insert features an 80-degree trigon (W) shape, a 0.3105-inch insert length, a 0.5-inch inscribed circle, and a 1/32-inch corner radius. It carries a tolerance code of M and a clearance code of N. Machinists and CNC operators in production and job-shop environments rely on this geometry for precision turning passes on challenging alloys.

This insert is engineered primarily for stainless steel workpieces and is also rated for superalloys and titanium as secondary workpiece materials, per SANDVIK COROMANT T-Max P series application guidelines. The MF chip breaker geometry is optimized for finishing and light-to-medium roughing cuts on these hard-to-machine material groups. Typical applications include shaft turning, facing, and profiling operations on components common in aerospace, medical, and chemical processing industries. The insert is held via clamp and pin methods, suiting standard WNMG-compatible toolholders.

Key Features

• TiAlN and AlCr2O3 PVD coating for heat resistance and extended tool life on stainless and superalloy materials
• 80-degree trigon insert shape (W) with neutral hand orientation for versatile turning and profiling
• MF chip breaker geometry suited to finishing and light-to-medium roughing passes
• 1/32-inch corner radius for controlled surface finish on tight-tolerance features
• Six cutting edges per insert maximizing cost-per-edge value
• Clamp and pin holding method compatible with standard WNMG toolholder systems

Compatibility

Designed for use in WNMG432-compatible indexable turning toolholders within the SANDVIK COROMANT T-Max P series. ISO code WNMG 08 04 08-MF 1125. Clamp and pin holding method required. Verify toolholder bore and seating geometry before installation.

Installation Notes

Insert indexing and replacement should be performed by a qualified machinist with the machine powered down and spindle locked. Use the appropriate torque wrench and manufacturer-specified clamping hardware when seating the insert to avoid micro-fractures in the carbide substrate. Inspect the toolholder pocket for wear or debris before seating a new insert. Follow your facility safety procedures and applicable OSHA machining guidelines during all tooling changes.
