Sandvik Coromant 5725221 Turning Insert CNMG543WMX 2015

Product Description

The SANDVIK COROMANT 5725221 is a CNMG-style indexable turning insert from the T-Max P series, designed for external and internal turning operations on CNC lathes and turning centers. Manufactured from solid carbide with a multilayer MTCVD-applied coating of TiCN, Al2O3, and TiN, this insert delivers wear resistance and thermal stability across demanding cutting conditions. The WMX chip breaker geometry is optimized for stainless steel and other ISO M-group materials. With a neutral hand configuration, 4 usable cutting edges, and an 80-degree diamond shape, the insert is a standard choice for licensed machinists and tool-room technicians running precision turning programs.

This insert is rated for primary use on stainless steel workpieces (ISO material code M) and is well suited to medium turning applications with a maximum depth of cut of 14.92 mm (0.5874 inches). The T-Max P series is a general turning platform used across aerospace, energy, and general engineering applications where consistent chip control and long tool life are required. The WMX chip breaker is specifically positioned for finishing to medium turning passes on work-hardening materials. Tooling is held via clamp and pin methods, making it compatible with standard CNMG toolholders found in most production turning setups.

Key Features

• MTCVD multilayer coating: TiCN base, Al2O3 thermal barrier, TiN top layer for wear indication and reduced friction
• WMX chip breaker geometry optimized for stainless steel (ISO M) turning with controlled chip evacuation
• 80-degree diamond insert shape (CNMG) provides 4 indexable cutting edges per insert
• 3/64 inch (0.0472 inch) corner radius for balanced edge strength and surface finish in medium turning
• Wiper edge included for improved surface finish without reducing feed rate
• Compatible with clamp and pin holding methods for secure seating in standard CNMG toolholders

Compatibility

Designed as an OEM-style indexable replacement for CNMG-style turning toolholders that accept a 5/8 inch inscribed circle insert with clamp and pin holding. ISO code CNMG160612WMX2015 identifies this insert within the SANDVIK COROMANT T-Max P series catalog.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Seat the insert fully into the pocket and confirm clamp and pin engagement before resuming cutting operations. Do not exceed the specified maximum depth of cut for the insert size, and verify toolholder and insert compatibility before mounting.
