Description
The SECO 02656577 is a solid carbide milling insert carrying ANSI and ISO designation ACET150612TR-MD15 in manufacturer grade MP3000. It is a parallelogram-shaped, single-sided, right-hand insert from the ACET-15 series, designed for indexable milling operations on hard materials, steel, and stainless steel. The insert features a TiAlN PVD coating applied over a micrograin solid carbide substrate, providing wear resistance and thermal stability at elevated cutting speeds. Two cutting edges are available per insert. The MD15 chip breaker geometry and positive rake angle of 15 degrees support controlled chip evacuation and reduced cutting forces during face and shoulder milling applications.
This insert is suited for indexable milling operations in metalworking environments, including job shops, production machining, and tool-and-die applications. It is optimized for cutting steel, stainless steel, and hard materials (ISO material groups P, M, and H). The insert is held in place by a screw-lock method and is compatible with specific SECO cutter bodies including R220.69-15H, R217.59-12, R220.59-12, R217.81, and R220.81. It is appropriate for applications requiring a maximum depth of cut up to 0.5827 inches and a cutting edge effective length of 0.5906 inches.

Compatibility
Compatible with SECO cutter series R220.69-15H, R217.59-12, R220.59-12, R217.81, and R220.81. Intended for machining steel, stainless steel, and hard materials per ISO material groups P, M, and H.
Installation Notes
Installation is performed by a machinist or tooling technician using the screw-lock mounting method standard to the compatible SECO cutter bodies. The machine spindle must be powered down and locked out before indexing or replacing inserts. Inspect the cutter pocket seating surface for debris or damage before seating the insert. Follow the cutter body manufacturer torque specifications for the insert clamping screw.
