Seco 02828044 Milling Insert LNKT080520PPTN-M06 MK2050

Product Description

The SECO 02828044 is a solid carbide milling insert in the LNKT-08 series, carrying the manufacturer grade MK2050 and ANSI/ISO designation LNKT080520PPTN-M06. The insert is double-sided with four cutting edges and features a PVD-applied dual coating of TiSiN and TiAlN for extended tool life in demanding milling operations. The rectangular shape with a 90-degree included angle, T-Land cutting edge style, and negative rake geometry make it well suited for high-productivity face and shoulder milling on hard workpiece materials. It is installed by machinists and CNC tooling technicians and held in the cutter body by a screw-type insert holding method.

This insert is designed for milling cast iron as its primary workpiece material, with steel and hard materials as secondary applications. The chip breaker designation M06 provides controlled chip formation across these material groups. The insert's negative rake angle of 15 degrees and T-Land edge preparation support stable cutting action in interrupted cuts and tough-to-machine alloys. It is compatible with cutters in the R335.18 series and is sold individually with a minimum order quantity of 10 units.

Key Features

• Solid carbide construction with medium grain material grade for toughness and wear resistance
• Dual PVD coating — TiSiN and TiAlN — for thermal and abrasion protection
• Double-sided insert with 4 cutting edges for extended usable life per insert
• T-Land cutting edge style with negative rake for stable performance in cast iron and hard materials
• M06 chip breaker geometry for controlled chip evacuation across cast iron, steel, and hard material applications
• Screw-type insert holding method for secure, repeatable seating in compatible cutter bodies

Compatibility

Compatible with R335.18 series cutter bodies. Suitable for milling cast iron, steel, and hard materials. Follows ANSI and ISO standards under designation LNKT080520PPTN-M06.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or removing inserts. Use the appropriate Torx or hex key to secure the clamping screw — do not overtighten by hand estimation; follow the cutter body manufacturer's fastener torque guidance. Inspect the insert pocket and clamping screw for wear or debris before each insert change.
