Iscar 5607357 Milling Insert T490 Lnmt 1306PNTR-CS IC810

Product Description

The ISCAR 5607357 is a solid carbide milling insert in the T490 LNMT 1306PNTR-CS IC810 series, designed for high-productivity face and shoulder milling operations. Part of the HELITANG cutter platform, this double-sided insert features a butterfly (LNMT) shape with a negative rake angle and a 90-degree included angle. The IC810 grade uses a PVD-applied AlTiCrN and TiN multilayer coating classified under the Sumotec PVD system, providing wear resistance suited to interrupted cuts and stable milling passes. With four usable cutting edges and a segmented chip breaker (CS), this insert delivers repeatable performance across tool changes. It is installed and indexed by machinists and tooling technicians working on CNC milling centers.

This insert is engineered for primary use on steel and cast iron workpieces, corresponding to ISO material codes P and K. The insert size code is 1306, with a maximum depth of cut of 12.50 mm (0.4920 inches). The segmented CS chip breaker geometry supports controlled chip formation in both roughing and semi-finishing passes on ferrous materials. It is a screw-held insert intended for right-hand cutter bodies. Compatible cutter series is the T490 LNK13 platform, making it a direct replacement insert for that toolholder family.

Compatibility

Designed for use in T490 LNK13 series cutter bodies. ANSI code T490 LNMT 1306PNTR-CS IC810; ISO code T490 LNMT 1306PNTR-CS. Conforms to ANSI and ISO 13399 standards.

Installation Notes

Installation is performed by qualified machinists or tooling technicians on CNC or manual milling equipment. Power down and lock out the spindle before indexing or replacing inserts. Use the correct torx or hex key to the cutter body manufacturer's specified seating procedure — do not overtighten the clamping screw, as this can crack the carbide. Inspect the insert pocket and seating surfaces for chips or debris before seating a new insert.
