Seco 02827865 Milling Insert XOMX180612TR-M14 MK2050

Product Description

The SECO 02827865 is a solid carbide milling insert with manufacturer part number XOMX180612TR-M14, graded MK2050 and designed for use in shoulder and face milling operations. The insert features a dual-layer PVD coating of TiSiN and TiAlN applied over a medium grain solid carbide substrate, delivering thermal resistance and edge stability at elevated cutting speeds. It carries a parallelogram shape with a 90-degree included angle, a positive rake geometry with a T-land cutting edge style, and a 3/64-inch corner radius. The maximum depth of cut is 0.6693 inches, and the cutting edge effective length matches at 0.6693 inches. Installation is performed by licensed machinists and CNC machine operators using a screw-type insert holding method.

This insert is suited for milling cast iron, steel, and hard materials in both production and job-shop environments. The MK2050 grade targets medium-grain cutting applications where edge toughness and coating durability are priorities. The M14 chip breaker geometry supports controlled chip evacuation across these workpiece materials. The insert is right-hand oriented and single-sided, with two available cutting edges per insert. Compatible cutter series include R217.69-18 and R220.69-18 per manufacturer specification.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. De-energize and lock out the machine spindle before seating or replacing inserts. Use the appropriate torx or hex key to secure the clamping screw to the manufacturer-specified method without over-torquing. Inspect the insert pocket for debris or damage before seating a new insert to ensure proper seating and repeatable runout.
