Seco 02743956 Milling Insert XOMX180631R-M10 MM4500

Product Description

The SECO 02743956 is a solid carbide milling insert carrying ANSI and ISO designation XOMX180631R-M10 in manufacturer grade MM4500. It is a single-sided, parallelogram-shaped insert with a positive rake geometry and a right-hand cutting orientation. The insert features a CVD-applied dual-layer coating of TiCN and Al2O3, which provides wear resistance and thermal stability during interrupted and continuous milling operations. With a 0.25 inch thickness, a 0.689 inch cutting edge effective length, and a 0.122 inch corner radius, this insert is engineered for precise material removal in demanding milling applications. It is installed by machinists and tool-and-die professionals on compatible milling cutter bodies.

This insert is rated primarily for stainless steel (ISO material code M) and is also suitable for steel (code P), superalloys, and titanium (code S). It fits milling cutter series R217.69-18 and R220.69-18. Typical applications include face milling and shoulder milling in aerospace, general machining, and industrial manufacturing environments where consistent surface finish and edge life on difficult materials are required. The M10 chip breaker geometry promotes reliable chip control across this range of workpiece materials.

Key Features

• CVD-coated with TiCN and Al2O3 for thermal and abrasion resistance
• Positive rake angle of 21 degrees reduces cutting forces on difficult materials
• 15-degree relief angle supports stable, chatter-resistant cuts
• Honed cutting edge style extends tool life on stainless steel and superalloys
• M10 chip breaker geometry for controlled chip evacuation
• Right-hand, screw-lock mounting for secure insert retention in compatible cutter bodies

Compatibility

Designed for use with SECO milling cutter series R217.69-18 and R220.69-18. Insert size code 180631 corresponds to ANSI and ISO designation XOMX180631R-M10.

Installation Notes

This insert is installed and serviced by qualified machinists or tooling technicians. Always power down and lock out the machine spindle before replacing inserts. Use the appropriate Torx or hex key as specified by the cutter body manufacturer when seating the clamping screw — do not overtighten, as this can fracture the carbide substrate. Inspect the cutter body pocket and seating surfaces for wear or debris before installing a new insert.
