Sandvik Coromant 5724067 Turning Insert CNMG431-WF 1525

Product Description

The SANDVIK COROMANT 5724067 is a solid carbide turning insert in the CNMG431-WF 1525 designation, part of the T-Max P series. It features a PVD-applied TiCN and TiN coating for wear resistance during continuous and interrupted turning operations. The insert has an 80-degree diamond shape (insert shape code C), a neutral hand orientation, and a wiper edge geometry. With a 0.5-inch inscribed circle and a 1/64-inch corner radius, this insert is sized for medium finishing and light roughing passes. Licensed machinists and CNC turning specialists install this insert on compatible toolholders using clamp and pin holding methods.

This insert is designed primarily for turning steel (ISO material code P) and is also rated for stainless steel applications (ISO material code M). The WF chip breaker geometry promotes controlled chip formation at moderate feed rates, making it well suited for finishing and semi-finishing operations on lathes and turning centers. It is applicable in both production shop and maintenance machining environments where consistent surface finish and edge life are required on ferrous workpiece materials.

Key Features

• PVD-coated with TiCN and TiN layers for extended tool life on steel and stainless steel
• Wiper edge geometry for improved surface finish at standard feed rates
• 80-degree diamond (CNMG) shape provides 4 usable cutting edges per insert
• Neutral hand orientation fits a wide range of CNMG-compatible toolholders
• WF chip breaker suited for finishing and semi-finishing passes on ferrous materials
• Clamp and pin holding method for secure, repeatable seating in the toolholder pocket

Compatibility

Designed for use in CNMG-style toolholders that accept a 1/2-inch inscribed circle insert with clamp and pin retention. ISO designation CNMG 12 04 04-WF 1525 can be used to cross-reference compatible toolholder specifications.

Installation Notes

Installation is performed by machinists or CNC tooling technicians on a powered-down machine with all axes at rest and spindle locked. The insert seats into the toolholder pocket and is secured via the clamp and pin method — ensure the pocket and locating pin are clean and free of chips before seating. Do not exceed the toolholder manufacturer's recommended clamping torque for the fastener. Inspect the cutting edge and coating condition before each use; a chipped or worn edge should be indexed or replaced before resuming cuts.
