Seco 02556930 Milling Insert Lnkt 050404PPTN4-M06 F40M

Product Description

The SECO 02556930 is a solid carbide milling insert designated LNKT 050404PPTN4-M06 in manufacturer grade F40M. This double-sided, rectangular insert features a fine-grain carbide substrate with a PVD-applied TiAlN and TiN coating for wear resistance at elevated temperatures. It carries four cutting edges and a negative rake geometry with a T-Land cutting edge style and a 15-degree rake angle. The insert measures 0.3937 inches in length, 0.1969 inches in width, and 0.1850 inches in thickness, with a corner radius of 0.0157 inches (1/64 inch). Maximum depth of cut is 0.1969 inches. It is used by machinists and tooling specialists in milling operations requiring reliable edge life across a range of workpiece materials.

This insert is designed for milling applications in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. The M06 chip breaker geometry supports moderate feed rates and chip control across these material families. It is suited for both roughing and semi-finishing passes where consistent edge performance and controlled chip evacuation are required. The insert is compatible with the SECO 335.18 cutter series. The neutral hand orientation and screw-in holding method make it straightforward to index or replace in the field.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. The machine spindle must be fully stopped and locked out before indexing or replacing inserts. Use the correct torque driver for the clamping screw to avoid seat damage or insert fracture. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert.
