Sandvik Coromant 5724675 Turning Insert CNMG431-PF 5015

Product Description

The SANDVIK COROMANT 5724675 is a solid carbide turning insert in the CNMG431-PF 5015 geometry, designed for external turning operations on CNC lathes and turning centers. Manufactured to ISO code CNMG 12 04 04-PF 5015, this insert features an 80-degree diamond shape, a neutral hand orientation, and an uncoated bright finish suited for applications where coating is not required or where a sharp, unaltered edge is preferred. It carries a 1/2-inch inscribed circle, a 1/64-inch corner radius, and is part of the T-Max P series. Machinists and CNC operators working in production turning environments install this insert into compatible toolholders that accept the CNMG form factor.

This insert is rated primarily for steel (ISO P) and secondarily for cast iron (ISO K), making it appropriate for general turning, finishing, and light interrupted cuts on those workpiece materials. The PF chip breaker geometry is optimized for finishing to semi-finishing passes, producing controlled chip evacuation at moderate feeds and depths of cut. It is typically used in precision turning cells where dimensional repeatability and surface finish are priorities. Four cutting edges are available per insert, supporting efficient cost-per-edge usage in high-throughput machining environments.

Key Features

• 80-degree diamond insert shape (CNMG) with neutral hand - fits a wide range of standard CNMG toolholders
• PF chip breaker geometry optimized for finishing and semi-finishing operations
• Solid carbide, uncoated bright finish - suitable for sharp-edge requirements or specific workpiece material conditions
• Four usable cutting edges per insert for improved cost-per-edge efficiency
• 1/64-inch corner radius for controlled surface finish in finishing applications
• Primary rating for steel (ISO P); secondary rating for cast iron (ISO K)

Compatibility

Designed for use in toolholders accepting the CNMG 431 insert form factor with clamp and pin holding method. ISO code CNMG 12 04 04-PF 5015 governs fitment. Consult the toolholder manufacturer specifications to confirm seat geometry and clamping compatibility before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Seat the insert fully against the pocket walls and tighten the clamp or pin per the toolholder manufacturer torque specifications. Inspect the insert pocket for wear or damage before seating a new insert, as a damaged pocket can cause premature edge failure or dimensional deviation.
