Iscar 5606043 Milling Insert T290 LNMT150608TR IC830

Product Description

The ISCAR 5606043 is a solid carbide milling insert from the SUMOMILL series, designated T290 LNMT150608TR in grade IC830. This double-sided, butterfly-shaped insert carries an AlTiN and TiN PVD coating applied via Sumotec PVD process, delivering hardness and thermal resistance for demanding milling applications. With a negative rake geometry, T-Land cutting edge style, and two usable cutting edges per insert, it is engineered for high-productivity face and shoulder milling. The insert seats in screw-in style toolholders and is installed by qualified machinists and tooling technicians running CNC milling equipment.

The T290 LNMT150608TR IC830 insert is designed for milling steel, stainless steel, superalloys, and titanium — material application codes P, M, and S. It fits T290-series cutter bodies and is well suited to production environments requiring consistent performance across these material families. The TR chip breaker geometry supports controlled chip flow during medium to moderate roughing passes. This insert is appropriate for both job-shop and production-floor applications where insert-to-insert consistency is critical.

Key Features

• IC830 grade solid carbide with AlTiN and TiN PVD Sumotec coating for heat and wear resistance
• Double-sided insert with 2 cutting edges — increases insert utilization and reduces per-edge cost
• Butterfly (LNMT) insert shape with 90-degree included angle and negative rake for stable cutting forces
• TR chip breaker for effective chip control in steel and stainless steel milling
• Maximum depth of cut of 0.5910 inches (15.00 mm) — supports full-depth shoulder passes
• Conforms to ANSI and ISO 13399 standards for tooling data interoperability

Compatibility

Designed for use with ISCAR T290-series cutter bodies accepting LNMT 150608 style inserts. Insert holding method is screw-type. Cutter series compatibility is listed as T290.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Power down and de-energize the machine spindle completely before seating or indexing inserts. Use the appropriate torx or hex key to the toolholder manufacturer specified torque when securing the clamping screw — do not overtighten. Inspect the insert pocket and seating surface for chips or debris before mounting to ensure proper insert support and runout.
