Iscar 5603718 Milling Insert Lnkx 1106PN-N Mm IC908

Product Description

The ISCAR 5603718 is a solid carbide milling insert carrying the ANSI designation LNKX 1106PN-N MM IC908. It belongs to ISCAR's TANGMILL series and is engineered for tangential milling operations where insert stability and heat resistance are critical. The insert is double-sided with four cutting edges, a butterfly (LNKX) shape, and a 90-degree included angle. The IC908 grade features a submicron carbide substrate with a TiAlN coating applied via PVD process, delivering strong wear resistance across a range of workpiece materials. The MM chip breaker geometry and T-Land cutting edge style help manage chip flow under moderate to aggressive feed conditions.

This insert is suited for milling steel, stainless steel, cast iron, superalloys, titanium, and hard materials — covering ISO material codes P, M, K, S, and H. The neutral hand orientation makes it adaptable to both climb and conventional milling setups. It is installed by machinists and toolroom technicians in CNC milling and machining center applications. The maximum depth of cut is 5.00 mm (0.197 inches), and the insert is held in the cutter body by screw clamping. Compatible cutter series include FDN, SDN, F90LN, and F86.

Key Features

• IC908 submicron carbide grade with TiAlN PVD coating for extended tool life in steel and stainless applications
• Double-sided insert with 4 cutting edges, reducing cost per edge
• MM chip breaker geometry with T-Land cutting edge for controlled chip formation
• Neutral hand orientation for flexible setup in right- or left-hand cutter bodies
• 0-degree relief angle (negative rake) for improved edge strength and stability
• Compliant with ANSI and ISO 13399 tooling data standards

Compatibility

Designed for use with ISCAR TANGMILL cutter bodies in series FDN, SDN, F90LN, and F86. Insert is screw-clamped and carries ANSI code LNKX 1106PN-N MM IC908 and ISO code LNKX 1106PN-N MM.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before seating or replacing inserts. Use the correct torque driver and insert screw specified by ISCAR for the cutter body series to avoid seat damage or screw failure. Inspect the insert pocket and clamping screw for debris or wear before installing a new insert.
