Iscar 5605473 Milling Insert T490 Lnmx 0804PN-R DT7150

Product Description

The ISCAR 5605473 is a solid carbide milling insert carrying the ANSI designation T490 LNMX 0804PN-R DT7150, designed for the HELITANG T490 LNK08 cutter series. This double-sided, butterfly-shaped insert features a helical cutting edge style and a negative rake geometry, delivering four usable cutting edges per insert. The Al2O3 and TiAlN coating applied via MTCVD and PVD processes provides wear resistance suited to demanding milling operations. At 0.2925 inches thick with a 0.1670-inch inscribed circle, the insert is engineered for precision fitment and consistent cutting performance in production milling environments.

This insert is intended for milling cast iron and hard materials in both production and job-shop settings. The right-hand orientation and chip breaker designation R support controlled chip evacuation at the depths typical of face and shoulder milling operations. The maximum depth of cut reaches 0.3150 inches (8.00 mm), making it applicable to medium-stock-removal passes on cast iron components such as engine blocks, housings, and machine bases. Installation requires a screw-holding method, consistent with standard T490-series toolholders.

Key Features

• Double-sided insert with 4 cutting edges, reducing per-edge tooling cost
• Helical cutting edge style with negative rake geometry for stable engagement in hard and cast iron materials
• Dual-process coating: Al2O3 via MTCVD plus TiAlN via PVD for combined thermal and wear resistance
• Maximum depth of cut of 0.3150 inches (8.00 mm) per pass
• Right-hand, screw-clamp insert with chip breaker R for predictable chip control
• Conforms to ANSI and ISO 13399 standards for broad toolholder compatibility within the T490 LNK08 series

Compatibility

Designed for use with the T490 LNK08 cutter series as specified by the manufacturer. Confirm toolholder designation T490 LNK08 before installation. No additional compatible model numbers were stated in the product data.

Installation Notes

This insert is installed by a machinist or toolroom technician using the screw-clamp method standard to T490-series milling cutter bodies. Ensure the spindle is fully stopped and the machine is locked out before indexing or replacing inserts. Inspect the insert pocket seat and clamping screw for wear or debris prior to seating a new insert. Follow the cutter manufacturer's torque guidance for the clamping screw and verify runout after assembly before resuming cuts.
