Seco 02573896 Cnmg 432-MF4 CP500 Turning Insert Carbide

Product Description

The SECO 02573896 is a solid carbide turning insert in the CNMG 432-MF4 series, designed for precision metal cutting in CNC lathe and turning center applications. It carries a CP500 grade designation with a multilayer PVD TiAlN and TiN coating applied over a carbide substrate. The insert features an 80-degree diamond shape (Insert Shape Code C), a neutral hand orientation, and a chamfered and honed cutting edge style. With a 0.5-inch inscribed circle and a corner radius of 0.0315 inches, it is built for finishing and medium machining passes where edge integrity and surface finish are critical. Machinists and CNC operators are the primary installers of this insert.

This insert is engineered primarily for stainless steel workpiece materials and is also rated for use on steel, cast iron, super-alloys, and titanium. The MF4 chip breaker geometry supports boring, facing, and turning operations. The insert seats in toolholders that use clamp, pin, or lever-lock holding methods. It conforms to ANSI and ISO standards and carries the ISO designation CNMG120408-MF4 and the industry standard number CNMG432-MF4. It is a multi-use insert suitable for a range of material grades including M10, M20, and M30 classifications.

Installation Notes

Installation is performed by machinists or CNC tooling technicians during scheduled insert changes on turning centers or manual lathes. Power down and lock out the spindle before seating or removing the insert. Use the appropriate torque wrench and manufacturer-specified seating hardware for the clamp, pin, or lever-lock system in use. Inspect the insert pocket for debris or wear before installing a new insert to ensure proper seating and prevent premature edge failure.
