Seco 02899502 Milling Insert SEEX1204AFN-M10 MS2050 Carbide

Product Description

The SECO 02899502 is a solid carbide milling insert carrying ANSI/ISO designation SEEX1204AFN-M10 in manufacturer grade MS2050. The insert is square in shape with a 90-degree included angle, four cutting edges, and a neutral hand orientation. It measures 0.5 inches in length and width with a thickness of 0.1874 inches and features a PVD-applied TiAlN and NbN dual coating over a micrograin carbide substrate. The M10 chip breaker geometry, combined with a 5-degree rake angle and honed cutting edge style, is engineered for controlled chip formation and reduced cutting forces in demanding milling applications. Licensed machinists and CNC programmers working in aerospace, energy, and precision manufacturing typically specify this insert for high-value workpiece materials.

This insert is designed primarily for milling superalloys and titanium (ISO material code S) and secondarily for steel and stainless steel (ISO codes P and M). It is suited for face milling, shoulder milling, and pocket milling operations where a positive rake geometry and tough PVD coating are required to manage heat and tool wear at the cutting zone. The insert seats via screw-holding method and delivers a maximum depth of cut of 0.3425 inches with a cutting edge effective length of 0.5 inches. It is a single-sided insert and is compatible with SECO cutter series R217.53-12 and R220.53-12.

Key Features

• Square SEEX insert style with 90-degree included angle and four available cutting edges for economy per edge
• M10 chip breaker with positive 5-degree rake and honed edge style for reduced cutting forces and controlled chip evacuation
• Maximum depth of cut of 0.3425 inches with a cutting edge effective length of 0.5 inches
• Neutral hand orientation provides flexible mounting in compatible cutter bodies
• ISO-standard SEEX1204AFN-M10 designation for direct cross-reference and tooling system integration

Compatibility

Compatible with SECO cutter series R217.53-12 and R220.53-12. Designed for machining superalloys, titanium, steel, and stainless steel workpiece materials per ISO material codes S, P, and M.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Before seating the insert, ensure the cutter body pocket and seating surfaces are clean and free of chips or debris. Secure the insert using the appropriate torx or hex key for the screw-holding mechanism per the cutter body manufacturer's tooling documentation. Inspect the insert seating and edge condition before initiating any cutting cycle.
