Iscar 5606068 Milling Insert T490 Lnht 130624PNTR IC330

Product Description

The ISCAR 5606068 is a solid carbide milling insert designed for high-performance metal removal in demanding machining applications. Carrying the ANSI and ISO 13399 designation T490 LNHT 130624PNTR IC330, this insert belongs to the HELITANG series and is engineered for use in T490 LNK13 cutter bodies. The IC330 grade features a PVD-applied TiCN plus TiN coating over a solid carbide substrate, targeting wear resistance and edge toughness at elevated cutting speeds. The double-sided, negative-rake geometry delivers four usable cutting edges per insert, reducing cost per edge in production environments. The helical cutting edge style and PNTR chip breaker promote smooth chip evacuation and reduce cutting forces on the workpiece.

This insert is intended for milling steel, stainless steel, superalloys, and titanium - material application codes P, M, and S under ISO classification. It suits face milling, shoulder milling, and ramping operations where a 90-degree included angle is required. The right-hand, screw-held mounting method is standard for HELITANG-style tooling systems. Typical users are CNC machinists and tooling engineers in job shops, aerospace, and general manufacturing facilities running medium to high cutting speeds on ferrous and difficult-to-machine materials.

Key Features

• IC330 grade with PVD TiCN plus TiN coating for toughness and wear resistance on steel and superalloys
• Double-sided insert with 4 cutting edges, maximizing value per insert in production runs
• Helical cutting edge style with PNTR chip breaker reduces cutting forces and improves chip control
• Negative rake, 90-degree included angle geometry suits shoulder and face milling operations
• Maximum depth of cut 0.4920 inches (12.50 mm) for aggressive material removal
• Screw-held insert mounting ensures rigid, repeatable seating in compatible toolholders

Compatibility

Designed for use with T490 LNK13 cutter series toolholders. ANSI code T490 LNHT 130624PNTR IC330; ISO code T490 LNHT 130624PNTR. Conforms to ANSI and ISO 13399 standards.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. Ensure the cutter body pocket and seating surfaces are clean and free of chips before seating the insert. Use the manufacturer-specified torx or hex key to tighten the clamping screw - do not over-torque or use impact tools. Verify insert orientation and hand (right-hand) matches the cutter body designation before beginning a cut.
