Iscar 5603355 Milling Insert Lnkx 1506PN-N Pl IC908

Product Description

The ISCAR 5603355 is a solid carbide milling insert carrying the ANSI and ISO designation LNKX 1506PN-N PL IC908. It is a double-sided, butterfly-shaped insert designed for use in tangential milling cutters. The IC908 grade is a submicron carbide substrate with a PVD-applied TiAlN coating, providing wear resistance and thermal stability across a wide range of workpiece materials. The insert has a neutral hand orientation, a negative rake geometry, and a T-Land cutting edge style. With four usable cutting edges and a maximum depth of cut of 0.276 inches, it is suited for productive face and shoulder milling operations. Installation is performed by machinists and CNC setup technicians using screw clamping.

This insert is intended for milling of steel, stainless steel, cast iron, superalloys, titanium, and hard materials, covering ISO material codes P, M, K, S, and H. It belongs to ISCAR's TANGMILL series and is compatible with milling cutter bodies in the FDN, SDN, SSB, F86, and F90 series. The PL chip breaker geometry is suited for general-purpose milling passes in both roughing and semi-finishing applications across these material groups. It fits standard LNKX 1506 pockets and is held by a screw-clamp method standard to the TANGMILL platform.

Key Features

• Double-sided insert with 4 cutting edges, reducing cost per edge
• Butterfly insert shape (LNKX) with 90-degree included angle for tangential mounting
• T-Land cutting edge style with negative rake for edge strength on hard and abrasive materials
• Maximum depth of cut of 0.276 inches with an effective cutting edge length of 0.5906 inches
• PL chip breaker geometry compatible with steel, stainless steel, cast iron, superalloys, titanium, and hard materials

Compatibility

Designed for use in ISCAR TANGMILL series cutter bodies, specifically those in the FDN, SDN, SSB, F86, and F90 cutter series that accept the LNKX 1506 insert pocket size.

Installation Notes

Installation is performed by a machinist or CNC tooling technician. Shut down and lock out the machine spindle before seating or removing inserts. Use the appropriate Torx or hex key as specified by the cutter body manufacturer for the screw-clamp pocket. Inspect the pocket seating surface for chips or debris before installing a new insert to ensure proper seating and avoid premature edge failure.
