Seco 02827866 Milling Insert XOMX180608TR-MD15 MK2050

Product Description

The SECO 02827866 is a solid carbide milling insert carrying ANSI and ISO designation XOMX180608TR-MD15 and manufacturer grade MK2050. This single-sided, right-hand insert features a parallelogram shape with a 90-degree included angle, a positive rake geometry at 15.9 degrees, and a T-Land cutting edge style. The MD15 chip breaker is paired with a dual-layer PVD coating of TiSiN and TiAlN, targeting productive material removal in cast iron and steel. With two cutting edges and a maximum depth of cut of 0.6693 inches, it suits high-feed face and shoulder milling operations performed by machinists and toolroom technicians.

This insert is designed for face milling and shoulder milling applications in production and job-shop environments. Primary workpiece material is cast iron (ISO material code K), with secondary suitability for steel and hard materials (ISO codes P and H). The MD15 chip breaker geometry promotes controlled chip formation across a range of cutting parameters. The screw-held mounting method is standard for this insert style. Compatible cutter series noted in manufacturer data are R217.69-18 and R220.69-18.

Key Features

• Solid carbide medium-grain substrate for wear resistance in cast iron and steel
• PVD-applied TiSiN and TiAlN dual coating for thermal and abrasion resistance
• MD15 chip breaker with T-Land cutting edge for controlled chip formation
• Positive rake angle of 15.9 degrees reduces cutting forces
• 2 cutting edges per insert; right-hand orientation
• Compatible with R217.69-18 and R220.69-18 cutter bodies per manufacturer data

Compatibility

Compatible with SECO cutter series R217.69-18 and R220.69-18 per manufacturer specification. Insert follows ANSI and ISO standard XOMX180608TR-MD15 designation.

Installation Notes

Installation is performed by machinists or toolroom technicians using the screw-held mounting method standard to this insert series. Ensure the cutter body and insert seat are clean and free of chips or debris before seating the insert. Torque the clamping screw according to the cutter body manufacturer specification sheet, not to a general value. Always disengage the machine spindle and follow lockout procedures before changing inserts.
