Seco 02743947 Milling Insert XOMX180608R-M10 MM4500

Product Description

The SECO 02743947 is a solid carbide milling insert carrying the manufacturer part designation XOMX180608R-M10 in the MM4500 grade. It features a parallelogram shape with a 90-degree included angle, a positive rake geometry at 22.4 degrees, and a right-hand cutting orientation. The insert is CVD-coated with a TiCN and Al2O3 multilayer finish applied to a coarse-grain solid carbide substrate, delivering wear resistance and thermal stability in demanding milling operations. Two cutting edges are available per insert, and a honed cutting edge style reduces chipping at entry. This insert is installed by machinists and tooling technicians in CNC milling applications.

This insert is suited for milling stainless steel as the primary workpiece material, with secondary application in steel, superalloys, and titanium. The M10 chip breaker geometry is designed to manage chip formation across these material groups. The XOMX series insert style and size code 180608 place this insert in a specific family of 18 mm class face and shoulder milling cutters. It is held in the cutter body by a screw-clamp method and is a single-sided insert, meaning the usable cutting edges are on one face only.

Key Features

• CVD-applied TiCN and Al2O3 coating for thermal and wear resistance in steel and stainless milling
• Positive rake angle of 22.4 degrees reduces cutting forces on difficult-to-machine materials
• Two cutting edges per insert with honed edge preparation to resist microchipping
• M10 chip breaker optimized for stainless steel, steel, superalloys, and titanium
• Right-hand cut, screw-mount, single-sided configuration for straightforward indexing
• Maximum depth of cut of 0.6693 inches with a 15-degree relief angle

Compatibility

Compatible with SECO cutter series R217.69-18 and R220.69-18 as specified by the manufacturer. Insert conforms to ANSI and ISO code XOMX180608R-M10 and meets ISO standards for insert geometry and designation.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the milling cutter body is completely de-energized and the spindle is locked before indexing or replacing inserts. Use the correct torx or hex key to the cutter body manufacturers specified torque for the screw-clamp seat — do not overtighten, as this can crack carbide inserts. Inspect the insert pocket seat for chips or debris before seating the new insert to ensure proper contact and runout.
