Seco 00064907 Turning Insert Spg 422 CP200 Carbide

Product Description

The SECO 00064907 is a solid carbide turning insert in the SPG (flat-top) style, designed for precision material removal in CNC turning, boring, and facing operations. It carries a multilayer TiAlN and TiN PVD coating under the manufacturer grade CP200, which provides thermal resistance and edge hardness suited to demanding cutting conditions. The insert features a square shape with a 90-degree included angle, a 0.5-inch inscribed circle, a 0.5-inch insert length, and a 1/32-inch (0.0315-inch) corner radius. The cutting edge is honed for consistent performance, and the flat-top chip breaker geometry produces a positive rake for reduced cutting forces.

This insert is primarily intended for machining stainless steel, superalloys, and titanium (ISO material groups M and S), with secondary capability on steel and cast iron (ISO groups P and K). It is suited for use in production turning centers and manual lathes where clamp-style toolholders accepting SPG-series inserts are in use. Applicable operations include external and internal turning, facing, and boring. The insert covers a maximum depth of cut of 0.4409 inches and an insert length range of 0.5 to 0.6 inches. ISO code SPGN120308 and industry standard number SPG422 apply. Compliant with ANSI and ISO insert standards.

Key Features

• Solid carbide substrate with multilayer TiAlN and TiN PVD coating, grade CP200
• Square insert shape with 90-degree included angle and positive rake geometry
• Four usable cutting edges per insert for extended tool economy
• Honed cutting edge style for consistent entry and reduced chipping risk
• Flat-top chip breaker suitable for finishing and semi-finishing passes
• Compatible with boring, facing, and turning operations in a single insert style

Compatibility

Designed as an OEM-style replacement insert for clamp-style toolholders accepting SPG-series square inserts with a 0.5-inch inscribed circle. ISO code SPGN120308 and industry standard number SPG422 define holder compatibility. Primary workpiece materials are stainless steel, superalloys, and titanium; secondary materials are steel and cast iron.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician using appropriate insert clamp hardware for SPG-style toolholders. Power down and de-energize the machine spindle before indexing or replacing inserts. Use proper insert handling tools to avoid contact with the honed cutting edge. Verify that the toolholder seating pocket is clean and free of chips before securing the insert to maintain dimensional accuracy.
