Seco 02827869 Milling Insert XOMX120408TR-MD13 MK2050

Product Description

The SECO 02827869 is a solid carbide milling insert carrying ANSI and ISO designation XOMX120408TR-MD13 in manufacturer grade MK2050. It features a parallelogram shape with a 90-degree included angle, a positive rake geometry of 14.6 degrees, and a T-Land cutting edge style. The insert is PVD-coated with a TiSiN and TiAlN multilayer finish for heat and wear resistance. With two cutting edges and a right-hand orientation, it is designed for high-productivity face and shoulder milling applications performed by machinists and tooling technicians on CNC machining centers.

This insert is suited for milling cast iron as its primary workpiece material, with secondary application in steel and hard materials. The MD13 chip breaker geometry is optimized to control chip flow and reduce cutting forces across these material groups. It fits into the XOMX-12 series insert pockets and is compatible with SECO cutter series R217.69-12 and R220.69-12. Typical installations include face milling, shoulder milling, and roughing-to-semi-finishing passes on ferrous and hardened workpieces in both production and job-shop environments.

Key Features

• PVD-applied TiSiN and TiAlN dual-layer coating for elevated heat resistance and extended tool life
• MD13 chip breaker geometry optimized for cast iron, steel, and hard material applications
• Positive rake angle of 14.6 degrees reduces cutting forces and power consumption
• T-Land cutting edge style provides edge reinforcement for interrupted cuts and hard materials
• Right-hand, single-sided insert with 2 usable cutting edges per insert
• Screw-held seating method for secure, repeatable indexing in compatible cutter bodies

Compatibility

Designed for use in SECO cutter series R217.69-12 and R220.69-12, which accept XOMX-12 series insert pockets. This insert carries ANSI and ISO code XOMX120408TR-MD13 and conforms to ISO standards for insert identification and fitment.

Installation Notes

This insert is installed and indexed by qualified machinists or tooling technicians. Before changing inserts, ensure the machine spindle is fully stopped, locked out, and the cutter body is secured. Use the appropriate torx or hex key as specified by the cutter body manufacturer to achieve proper clamping torque without over-tightening the retaining screw. Inspect the insert pocket seat and screw threads for debris or damage before seating each new insert.
