Iscar 5603833 Milling Insert Lnkx 1506PN-N Pl IC928

Product Description

The ISCAR 5603833 is a solid carbide milling insert carrying the ANSI designation LNKX 1506PN-N PL IC928. It belongs to ISCAR's TANGMILL series and is designed for tangential milling operations where high edge strength and thermal resistance are required. The insert features a butterfly (LNKX) shape with a negative rake angle and a T-Land cutting edge style. A PVD-applied TiAlN coating provides wear resistance across demanding cutting conditions. Four usable cutting edges and a double-sided configuration extend tool life per insert. Licensed metalworking professionals and CNC machinists install this insert in compatible tangential milling cutters.

This insert is suited for milling steel, stainless steel, superalloys, and titanium in both roughing and semi-finishing applications. The IC928 grade is positioned for materials classified under ISO P, M, and S workpiece material codes. The screw-held, neutral-hand design supports consistent seating in compatible cutter bodies. A maximum depth of cut of 0.276 inches (7.00 mm) and a cutting edge effective length of 0.5906 inches make it appropriate for moderate to aggressive radial engagement in production milling environments on machining centers and mill-turn platforms.

Key Features

• Butterfly (LNKX) insert shape with 90-degree included angle for tangential mounting
• IC928 grade with PVD TiAlN coating for heat and wear resistance in ferrous and difficult-to-cut materials
• Double-sided insert with 4 cutting edges for maximum economy per insert
• T-Land cutting edge style improves edge strength and reduces chipping risk
• Neutral hand orientation compatible with left- and right-hand cutter configurations
• Maximum depth of cut of 0.276 inches (7.00 mm) supports aggressive material removal rates

Compatibility

Compatible with ISCAR TANGMILL cutter series bodies including FDN, SDN, SSB, F86, and F90. Designed for use with screw-type insert clamping systems on those platforms.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. Ensure the cutter body is fully de-energized and the spindle is locked before seating or removing inserts. Use the correct torx or hex key specified by the cutter body manufacturer when tightening the clamping screw — do not overtighten, as this can fracture the carbide insert. Inspect the insert pocket for chips, debris, or wear before seating a new insert to ensure proper contact and repeatable runout.
