Seco 02638284 Milling Insert XOEX120431R-M07 MS2500

Product Description

The SECO 02638284 is a solid carbide milling insert carrying the ANSI/ISO designation XOEX120431R-M07 and manufactured to SECO grade MS2500. The insert features a parallelogram shape with a positive rake geometry, a 15-degree rake angle, and a 15-degree relief angle. A CVD-applied dual-layer coating of TiCN and Al2O3 provides thermal protection and wear resistance during high-temperature cutting. The right-hand, single-sided insert holds two cutting edges and is secured by screw clamping. With a corner radius of 0.122 inches and a maximum depth of cut of 0.4724 inches, this insert is suited for demanding material-removal operations performed by CNC machinists and tooling specialists.

This insert is designed primarily for milling superalloys and titanium, with secondary application in steel and stainless steel. The M07 chip breaker geometry is optimized for medium-grain cutting conditions where chip control and edge stability are critical. Typical use cases include face milling, shoulder milling, and precision profiling operations in aerospace, energy, and precision-machining environments where workpiece materials demand consistent edge performance across multiple passes.

Key Features

• CVD coating of TiCN and Al2O3 for thermal and abrasion resistance in high-temperature alloy cutting
• Positive rake geometry with 15-degree rake and 15-degree relief angle reduces cutting forces
• Corner radius of 0.122 inches supports stable finishing and semi-finishing passes
• M07 chip breaker optimized for superalloys, titanium, steel, and stainless steel
• Right-hand, single-sided design with two cutting edges per insert
• Screw-held insert style for secure, repeatable seating in compatible cutter bodies

Compatibility

Compatible with SECO cutter series R217.69-12 and R220.69-12 as specified by the manufacturer. This insert carries ANSI and ISO code XOEX120431R-M07 and belongs to the XOEX-12 series.

Installation Notes

Installation is performed by CNC tooling technicians or machinists. Ensure the cutter body is fully de-energized and the spindle is locked before changing inserts. Use the correct torx or hex key specified for the cutter body screw to avoid stripping the insert pocket seat. Inspect the pocket and screw threads for debris or damage before seating a new insert.
