Product Description
The SECO 00030430 is a solid carbide ball nose milling insert designed for high-performance material removal in demanding milling applications. Manufactured to ANSI and ISO standards under the 218.20-080ER-M04 designation, this insert features a TiAlN and TiN dual-layer PVD coating applied over fine-grain solid carbide substrate. It carries the F40M manufacturer grade with a positive rake geometry and honed cutting edge style, delivering clean, controlled cuts. The insert measures 0.6157 inches in length, 0.2709 inches wide (inscribed circle), and 0.1264 inches thick, with a corner radius of 0.3150 inches and a maximum depth of cut of 0.5510 inches. Two right-hand cutting edges are provided per insert.
This insert is suited for milling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, making it appropriate for aerospace, automotive, die-and-mold, and general machining environments. The M04 chip breaker geometry supports a broad range of cutting conditions. It is held in the cutter body by screw and is designed for single-sided use with a positive 1-degree rake angle and an 11-degree relief angle. CNC machining centers running contouring, profiling, or 3D surface work are the primary install context.

Compatibility
Compatible with cutter series R218.20-16, R218.20-0.625, and R218.24-R080. Insert size code 080ER; series 218.20-080.
Installation Notes
Installation is performed by qualified machinists or tooling technicians following standard insert indexing procedures. Power down and lock out the spindle before removing or seating any insert. Use the appropriate torx or hex key specified by the cutter body manufacturer when tightening the clamping screw do not overtighten or use impact tools on insert screws. Inspect the insert pocket and clamping screw for wear or contamination before seating a new insert.
