Sandvik Coromant 5724066 CNMG431-WF Turning Insert

Product Description

The SANDVIK COROMANT 5724066 is a CNMG-style indexable turning insert in the T-Max P series, designed for external turning operations on CNC lathes and machining centers. It features a multilayer MTCVD coating of TiCN, Al2O3, and TiN applied over a solid carbide substrate in manufacturer grade 1515, delivering wear resistance and thermal stability in continuous and interrupted cuts. The insert has an 80-degree diamond shape, a neutral hand orientation, a 0.5000-inch inscribed circle, and a corner radius of 0.0157 inch (1/64 inch). Four usable cutting edges and a WF chip breaker geometry make it well suited for finishing and light roughing passes. Licensed machinists and CNC operators install this insert as a standard indexable tooling component.

This insert is intended for machining steel as its primary workpiece material (ISO code P) and stainless steel as a secondary application (ISO code M). The WF chip breaker geometry promotes chip control in finishing and semi-finishing operations at moderate feed rates. The T-Max P series is a platform commonly used in high-production turning cells where consistent surface finish and dimensional accuracy are required. The insert seats via clamp and pin holding methods in compatible CNMG toolholders.

Key Features

• MTCVD multilayer coating: TiCN, Al2O3, and TiN for extended tool life in steel and stainless steel
• 80-degree diamond insert shape (Shape Code C) with neutral hand orientation
• WF chip breaker geometry optimized for finishing and semi-finishing passes
• Four indexable cutting edges for cost-effective tool management
• 0.5000-inch inscribed circle with a 0.0157-inch corner radius for tight-tolerance work
• Maximum depth of cut of 0.4921 inch (12.50 mm)

Compatibility

Designed for use in CNMG-style toolholders that accept clamp and pin holding methods; ISO code CNMG120404WF1515 identifies the insert geometry for cross-referencing to compatible toolholder bores with a 0.2032-inch hole diameter.

Installation Notes

Index or replace turning inserts only after the machine spindle has come to a full stop and the lathe or machining center has been locked out per applicable machine-guarding procedures. Use the correct torque driver or clamp screw specified by the toolholder manufacturer to secure the insert; over-tightening the clamp screw can chip the cutting edge or damage the seat. Inspect the insert pocket and shim for wear or debris before seating a new insert. Insert indexing is typically performed by a CNC machinist or toolroom technician following the toolholder manufacturer's seating instructions.
