Iscar 5606075 Milling Insert T490 Lnht 130664PNTR IC830

Product Description

The ISCAR 5606075 is a solid carbide milling insert in the HELITANG series, designed for high-performance face and shoulder milling operations on steel, stainless steel, superalloys, and titanium. It carries the ANSI designation T490 LNHT 130664PNTR IC830 and features a butterfly (LNHT) insert shape with a helical cutting edge style and negative rake geometry. The IC830 grade substrate is finished with an AlTiN and TiN PVD coating classified under ISCARs Sumotec PVD process, optimizing wear resistance and thermal stability in demanding cut conditions. Two cutting edges are available per insert, and the double-sided configuration supports extended tool life per unit cost.

This insert is used in milling applications targeting steel (P), stainless steel (M), superalloys, and titanium (S) workpiece materials. It is suited for right-hand cutting in shoulder and ramping operations where consistent chip control and edge stability are required. Compatible with the T490 LNK13 cutter series, this insert is installed in indexable milling toolholders by machinists and CNC operators in production and job-shop environments. The PNTR chip breaker geometry is selected for controlled chip formation across these workpiece material groups.

• Compliant with ANSI and ISO 13399 standards

Compatibility

Compatible with the T490 LNK13 cutter series. ANSI code T490 LNHT 130664PNTR IC830; ISO code T490 LNHT 130664PNTR.

Installation Notes

Installation is performed by a machinist or CNC tooling technician. Disengage machine power and lock out the spindle before indexing or replacing inserts. Use the appropriate torx or hex key to seat the insert securely via the screw-holding method; do not overtighten, as this can crack the carbide substrate. Verify insert orientation and hand designation match the toolholder specification before resuming cuts.
