Seco 02899473 Milling Insert XOEX120408R-M07 MS2050 Carbide

Product Description

The SECO 02899473 is a solid carbide milling insert identified by ANSI and ISO code XOEX120408R-M07, manufactured to the MS2050 grade with a PVD-applied TiAlN and NbN coating. This single-sided, right-hand parallelogram insert carries a positive rake angle of 20.3 degrees and a honed cutting edge style. It is designed for high-performance milling of superalloys, titanium, steel, and stainless steel, and belongs to the XOEX-12 series. With two cutting edges and a micrograin carbide substrate, the insert delivers edge stability and wear resistance in demanding milling applications. Licensed machinists and CNC tooling specialists are the primary installers of this insert type.

This insert is suited for milling operations in both production and job-shop environments where difficult-to-machine materials such as superalloys and titanium are common. It also performs well on steel and stainless steel workpieces. The M07 chip breaker geometry is optimized for these material groups, controlling chip flow and reducing cutting forces during face and shoulder milling cycles. Compatible cutter series include the R217.69-12 and R220.69-12, making it a direct-fit replacement insert for those tool bodies. The insert is held in the cutter body by a screw-type clamping method.

• Positive rake angle of 20.3 degrees with honed cutting edge for reduced cutting forces
• M07 chip breaker geometry for effective chip control in difficult-to-machine materials
• Two cutting edges per insert on a single-sided parallelogram body
• Screw-type insert holding for secure seating in compatible cutter bodies

Compatibility

Designed for use in SECO cutter series R217.69-12 and R220.69-12 tool bodies. Insert conforms to ANSI and ISO code XOEX120408R-M07 within the XOEX-12 series.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Always power down and lock out the machine spindle before changing inserts. Use the correct torx or hex key specified by the cutter body manufacturer when tightening the clamping screw — do not overtighten, as this can fracture the carbide insert. Inspect the cutter pocket seating surface for debris or damage before seating the new insert.
