Sandvik Coromant 5725294 CNMG432-PF 1525 Turning Insert

Product Description

The SANDVIK COROMANT 5725294 is a CNMG432-PF 1525 indexable turning insert designed for external and internal turning operations on CNC lathes and turning centers. Manufactured from carbide and finished with a PVD-applied TiCN and TiN dual coating, this insert delivers wear resistance and edge stability across a range of cutting conditions. It features an 80-degree diamond shape, a neutral hand orientation, and a PF chip breaker geometry suited for finishing and light roughing passes. With four cutting edges available per insert, it provides solid value in high-volume production environments. Licensed machinists and CNC turning technicians are the primary installers and operators of this insert.

This insert is engineered for turning steel as its primary workpiece material, with secondary suitability for stainless steel and cast iron. It fits applications where controlled chip formation and surface finish consistency are critical. The PF chip breaker geometry is optimized for finishing cuts at lower depths of cut and feed rates. This insert belongs to the T-Max P series, which is a widely used platform in precision turning across both job shop and production environments. Applications span general-purpose steel turning through to light stainless and cast iron work.

Key Features

• 80-degree diamond insert shape provides a sharp, strong cutting edge geometry suited for finishing passes
• TiCN and TiN dual coating applied via PVD process improves surface hardness and reduces built-up edge on steel
• PF chip breaker geometry promotes controlled chip evacuation during finishing and light roughing operations
• Four usable cutting edges per insert reduce per-edge tooling cost in production turning
• Neutral hand orientation provides flexibility in both right-hand and left-hand toolholder setups
• Compatible with clamp and pin insert holding methods for secure seating in standard CNMG toolholders

Compatibility

Designed as an OEM-style replacement insert for use in standard CNMG toolholders that accept the CNMG 432 insert size. ISO code CNMG 12 04 08-PF 1525 identifies the exact form factor for toolholder matching. Compatible with clamp and pin holding systems.

Installation Notes

Insert installation and indexing should be performed by a qualified CNC machinist or turning technician with the machine fully stopped and in an energy-isolated state per lockout/tagout procedures. Use the appropriate torque wrench for the clamping screw to avoid cracking the carbide substrate - refer to the toolholder manufacturer specification for clamp torque. Inspect the insert pocket and seating surfaces for chips or debris before seating a new edge. Confirm correct insert orientation and chip breaker direction relative to the programmed feed direction before resuming operation.
