Seco 10207741 Carbide Milling Insert Loex MK2050

Product Description

The SECO 10207741 is a double-sided carbide milling insert designed for high-performance face and shoulder milling operations. It carries the ANSI/ISO designation LOEX120708TR-T4-M12 and is manufactured to grade MK2050 with a PVD-applied TiSiN and TiAlN dual-coating. The insert features a rectangular shape with a 90-degree included angle, a negative rake geometry at 35 degrees, and a T-Land cutting edge style. Four cutting edges are available per insert. The corner radius measures 0.0315 inches (1/32 inch), and the maximum depth of cut reaches 0.4724 inches. Licensed machinists and CNC tooling technicians install this insert in compatible Seco cutter bodies.

This insert is suited for milling cast iron and hard materials in both production and job-shop environments. The double-sided configuration extends tool life by providing four usable cutting edges. The MK2050 grade and PVD coating combination supports stable cutting performance at elevated surface speeds typically encountered when machining hardened steels and cast components. The M12 chip breaker geometry promotes controlled chip evacuation in medium to heavy interrupted cuts. This insert is compatible with Seco cutter series R217/220.94-12, making it a direct-fit option for existing tooling setups using that platform.

Installation Notes

Installation is performed by qualified CNC tooling technicians or machinists. Ensure the cutter body is fully de-energized and spindle is locked before seating or replacing inserts. Use the appropriate Torx or hex key as specified by the cutter body manufacturer to secure the clamping screw without over-torquing. Inspect the insert pocket seating surface for chips or debris before fitting a new insert.
