Seco 02439189 Milling Insert Trigon F15M Solid Carbide

Product Description

The SECO 02439189 is a solid carbide milling insert in the 218.19-100T-MD08 series, designed for high-performance milling of hard materials, cast iron, and non-ferrous metals. This trigon-shaped, single-sided insert carries a manufacturer grade of F15M and features a TiAlN and TiN dual-coating applied via PVD process for extended tool life and thermal resistance. With a 60-degree included angle, three cutting edges, a neutral rake, and a T-Land cutting edge style, this insert delivers controlled chip formation in demanding milling applications. It is installed by machining professionals and CNC tooling specialists working in precision manufacturing environments.

This insert is suited for milling operations targeting hard materials (ISO material code H), with secondary applicability to cast iron (K) and non-ferrous metals (N). The MD08 chip breaker geometry is optimized for these work materials. Typical use cases include face milling and shoulder milling on CNC machining centers where tight tolerances and consistent surface finish are required. The insert is compatible with the R218.19-20 and R217.21-R100 cutter series as specified by the manufacturer.
