Seco 02656032 Milling Insert Trigon Solid Carbide MP3000

Product Description

The SECO 02656032 is a solid carbide trigon milling insert with ANSI and ISO designation 218.19-160T-04-MD09, designed for indexable milling operations in demanding material applications. It carries the MP3000 micrograin carbide grade and features a PVD-applied TiAlN coating for wear resistance and thermal stability. The insert has a neutral rake and neutral hand orientation, a 12-degree relief angle, a T-Land cutting edge style, and an MD09 chip breaker geometry. With three cutting edges and a 0.187-inch thickness, this single-sided insert is engineered for consistent performance in high-hardness and ferrous material cutting. Installation uses a screw-type insert holding method.

This insert is suited for milling steel, stainless steel, and hard materials, covering ISO material groups P, M, and H. The MD09 chip breaker geometry supports controlled chip formation in these workpiece materials. It is used by CNC machinists and toolroom professionals in indexable milling cutter bodies requiring the 160T-04 insert size format. Compatible cutter series listed by the manufacturer include R218.19-32, R217.21-R160, and R220.21-R160. Typical applications include face milling, shoulder milling, and profile milling passes on hardened ferrous components.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. The insert is secured using a screw-type clamping method — ensure the screw and seat are clean and free of chips before seating the insert. Power down and lock out the machine spindle before changing inserts. Do not exceed the cutter body manufacturer's specified depth-of-cut or feed-rate limits for this insert size and grade.
