Seco 02809856 Milling Insert ONMU050410ANTN-ME10 F40M

Product Description

The SECO 02809856 is a solid carbide milling insert carrying grade designation F40M and ANSI/ISO code ONMU050410ANTN-ME10. This double-sided, octagon-shaped insert features 16 usable cutting edges, a negative rake geometry with a T-Land cutting edge style, and a 20-degree rake angle. The TiAlN and TiN dual-layer PVD coating delivers thermal resistance and wear performance suited to demanding milling applications. With a maximum depth of cut of 0.1535 inches and an inscribed circle of 0.4724 inches, the insert is designed for high-productivity face and shoulder milling in steel, cast iron, superalloys, and titanium. It is installed and maintained by machining professionals and CNC tooling technicians.

This insert is suited for use in both conventional and CNC milling operations across a range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. The ME10 chip breaker geometry supports stable chip control during roughing and semi-finishing passes. It is compatible with SECO cutter series R217.48-05 and R220.48-05 and is held in the cutter body by a screw-type clamping method. Applications span general-purpose industrial machining environments requiring consistent edge life across mixed-material production runs.

Key Features

• 16 cutting edges on a double-sided octagon insert body maximize edge utilization per insert
• F40M fine-grain solid carbide substrate with TiAlN and TiN PVD dual-layer coating for thermal and wear resistance
• ME10 chip breaker geometry supports controlled chip formation in steel and cast iron applications
• Negative rake with T-Land edge prep reduces cutting forces and improves edge stability
• Maximum depth of cut of 0.1535 inches with a 0.0394-inch corner radius for consistent surface finish
• Screw-mount insert holding method ensures secure seating in compatible cutter bodies

Compatibility

Compatible with SECO cutter series R217.48-05 and R220.48-05. Designed for use with screw-type insert clamping systems within the ONMU-05 series tooling platform.

Installation Notes

Installation is performed by qualified machining or CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct Torx or hex key specified by the cutter body manufacturer to seat the clamping screw — do not overtighten. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert edge.
