Sandvik Coromant 5756764 WNMG432-QM 1115 Turning Insert

Product Description

The SANDVIK COROMANT 5756764 is a WNMG432-QM 1115 grade solid carbide turning insert from the T-Max P series, designed for high-performance external turning operations on CNC lathes and turning centers. The insert features a dual-layer PVD coating of TiAlN and AlCr2O3, providing heat and wear resistance during demanding cuts. With an 80-degree trigon shape, a 1/2-inch inscribed circle, and a 1/32-inch corner radius, this insert is engineered for stable engagement and reliable chip control. The QM chip breaker geometry is optimized for medium to finishing passes. Machinists and CNC operators working with precision turning applications will find this insert well-suited for controlled material removal rates.

This insert is primarily intended for turning stainless steel, with secondary suitability for superalloys and titanium - materials that demand sharp, wear-resistant cutting edges and effective chip evacuation. The neutral hand configuration makes it compatible with standard WNMG-style toolholders used in both OD turning and facing operations. Typical installation scenarios include production turning on horizontal or vertical CNC turning centers in industrial and aerospace machine shops. The T-Max P series designation indicates compatibility with SANDVIK COROMANT T-Max P toolholder systems designed for WNMG insert pockets.

Key Features

• WNMG432 trigon insert shape with 80-degree included angle for versatile turning geometry
• Grade 1115 solid carbide substrate with PVD-applied TiAlN and AlCr2O3 dual-layer coating for elevated temperature resistance
• QM chip breaker geometry optimized for stainless steel and superalloy turning at medium to light depths of cut
• 1/32-inch corner radius suitable for medium-finish turning passes
• 6 cutting edges per insert for extended tooling economy
• Neutral hand orientation compatible with standard WNMG clamp-and-pin style toolholders

Compatibility

Designed for use in WNMG-style toolholders that accept clamp and pin insert holding, consistent with the T-Max P series platform. Primary workpiece material code M (stainless steel) and secondary code S (superalloy and titanium). ISO designation WNMG 08 04 08-QM 1115.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. Power down and lock out the machine spindle before seating or removing inserts. Ensure the toolholder pocket and seating surfaces are clean and free of chips before installing the insert to prevent seating errors. Follow the toolholder manufacturer torque guidelines for the clamping screw - do not over-torque, as this can crack the carbide substrate.
