Description

The SECO 02828045 is a solid carbide milling insert with ANSI and ISO designation LNKT080516PPTN-M06, manufactured to the MK2050 grade. It carries a dual PVD coating of TiSiN and TiAlN, which supports cutting performance in cast iron and steel applications. The insert features a rectangular shape with a 90-degree included angle, a negative rake geometry at 15 degrees, and a T-Land cutting edge style with the M06 chip breaker. With four usable cutting edges on a double-sided body, it is designed for indexable milling operations where consistent edge performance and insert economy matter. Licensed machinists and CNC setup technicians are the primary installers and users.

This insert is intended for milling applications in cast iron as its primary workpiece material, with secondary compatibility for steel and hard materials. The M06 chip breaker designation targets medium-duty cutting conditions. It fits the R335.18 cutter series and is classified under the LNKT-08 series. The insert is held in the cutter body by a screw-clamp method, which is standard for this style. Typical applications include face milling and shoulder milling operations on machining centers and CNC mills across both job shop and production environments.

Compatibility

Designed for use with the R335.18 cutter series. Compatible with LNKT-08 series toolholders. Suitable for machining cast iron, steel, and hard materials. The ANSI and ISO code for this insert is LNKT080516PPTN-M06.

Installation Notes

Insert indexing and replacement should be performed by a qualified machinist with the machine fully powered down and the spindle locked. Use the appropriate torx or hex key to release the clamping screw before indexing or replacing the insert. Inspect the insert seat and clamp for wear or debris before seating a new insert. Follow the toolholder manufacturer torque specification for the clamping screw to avoid insert cracking or seat damage.
