Iscar 5606325 Milling Insert T490 Lnmt 1306PNTR IC830 Carbide

Product Description

The ISCAR 5606325 is a solid carbide milling insert carrying the ANSI designation T490 LNMT 1306PNTR IC830. It belongs to the HELITANG series and is designed for use in T490 LNK13 cutter bodies. The insert features a butterfly (LNMT) shape with a helical cutting edge style, a negative rake geometry, and a 90-degree included angle. Four cutting edges are available per insert, making it a double-sided design. The IC830 grade substrate is finished with an AlTiN and TiN PVD coating classified under ISCARs Sumotec PVD system, delivering thermal stability and wear resistance in demanding milling applications. Cutting edge effective length is 0.5409 inches, maximum depth of cut is 0.4920 inches, and the corner radius measures 0.0315 inches (1/32 inch).

This insert is suited for shoulder milling and helical interpolation operations on steel, stainless steel, superalloys, and titanium workpieces (ISO material codes P, M, and S). The PNTR chip breaker geometry manages chip formation across this range of materials. Typical install scenarios include production machining centers and CNC milling operations where secure screw-clamped insert seating is required. The right-hand cutting configuration and negative rake make it compatible with high-feed and high-speed milling strategies on the T490 platform.

Key Features

• IC830 grade solid carbide with AlTiN and TiN PVD (Sumotec) coating for extended tool life in steel and superalloy milling
• Double-sided insert with 4 usable cutting edges per insert, reducing cost per edge
• Helical cutting edge style with PNTR chip breaker for controlled chip evacuation
• Maximum depth of cut 0.4920 inches (12.50 mm) per pass
• Corner radius 0.0315 inches (0.79 mm) for general-purpose shoulder profiling
• Screw-held mounting method; right-hand insert orientation
• Compliant with ANSI and ISO 13399 insert identification standards

Compatibility

Designed for use with T490 LNK13 series cutter bodies. ANSI code T490 LNMT 1306PNTR IC830; ISO code T490 LNMT 1306PNTR. Confirm cutter body pocket specifications before installation.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Disengage machine power and confirm spindle lock before seating or replacing inserts. Use the correct ISCAR torx or hex key for the clamping screw to avoid overtorque and insert fracture. Inspect the pocket seating surface for chips or debris before installing a new insert edge.
