Seco 02656058 Milling Insert SEEX09T3AFN-M05 MP3000 Carbide

Product Description

The SECO 02656058 is a solid carbide milling insert carrying ANSI and ISO designation SEEX09T3AFN-M05 in the MP3000 manufacturer grade. This single-sided, square-shape insert features a TiAlN coating applied via PVD process and is designed for indexable milling operations on hard materials, steel, and stainless steel. It provides 4 cutting edges per insert, a neutral rake angle of 0 degrees, and a honed cutting edge style. At 0.1563 inches thick with a 3/8 inch inscribed circle and a maximum depth of cut of 0.2795 inches, it is suited to medium-to-finish milling passes where edge consistency and coating durability matter. Installation and indexing are performed by a licensed machinist or toolroom technician.

This insert is intended for use in indexable milling cutters on CNC and manual milling machines. It is rated for primary application in hard material (ISO code H) and secondary application in steel and stainless steel (ISO codes P and M). The M05 chip breaker geometry is optimized for controlled chip formation in these material groups. The insert is compatible with SECO cutter series R217.53-09 and R220.53-09 as specified by the manufacturer. Typical use cases include face milling, shoulder milling, and profiling operations in job shop and production environments.
