Seco 02899465 Trigon Milling Insert MS2050 Solid Carbide

Product Description

The SECO 02899465 is a solid carbide trigon milling insert in the XNEX-08 series, designed for high-performance face and shoulder milling on difficult-to-cut materials. Manufactured to ANSI and ISO code XNEX080608R-M08, this insert carries a PVD-applied TiAlN and NbN coating in manufacturer grade MS2050 for extended tool life in demanding applications. The double-sided geometry provides 6 cutting edges per insert, a negative rake angle, and a 1/32-inch corner radius. The M08 chip breaker controls chip flow effectively during interrupted or continuous cuts. Installation and tooling changes are handled by qualified machinists or CNC tooling technicians.

This insert is intended for milling operations in metalworking environments where superalloys, titanium, steel, and stainless steel are the primary workpiece materials. The right-hand cutting configuration and negative rake geometry make it suited for stable, high-feed milling passes. The M08 chip breaker is optimized for medium-to-finishing cuts in these material groups. Compatible cutter series is R220.96-08. The insert seats and is held in place via screw-clamp mounting, which is standard for XNEX-style toolholders. Sold individually; minimum order quantity is 10 units.

Key Features

• Solid carbide micrograin substrate with PVD TiAlN and NbN coating for heat and wear resistance
• Double-sided insert with 6 usable cutting edges for cost efficiency
• M08 chip breaker geometry optimized for steel, stainless steel, superalloys, and titanium
• 1/32-inch corner radius (0.0315 inches) for controlled surface finish and edge strength
• Maximum depth of cut 0.2953 inches; effective cutting edge length 0.2953 inches
• Right-hand cut, negative rake, honed cutting edge style for stable engagement
• Screw-clamp insert holding method; compatible with R220.96-08 cutter series

Compatibility

Designed for use with the R220.96-08 cutter series. ANSI and ISO code XNEX080608R-M08 confirms fitment in XNEX-08 series toolholders that accept screw-mounted trigon inserts with an 0.1811-inch hole diameter.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or replacing inserts. Use the correct Torx or hex key to tighten the clamping screw to the toolholder specification — do not over-torque, as this can crack the carbide body. Inspect the insert seat and pocket for chips or debris before seating a new insert.
