Iscar 4818353 Indexable Drill Insert NPMT08RG IC908

Product Description

The ISCAR 4818353 is a solid carbide indexable drill insert in the NPMT08RG configuration, designed for use in FINEBEAM series indexable drilling systems. The insert carries the IC908 manufacturer grade and features a PVD-applied TiAlN coating, which provides thermal resistance and wear protection during high-speed cutting operations. With an insert size code of 08, it measures 8 mm (0.315 inches) in width and 10 mm (0.394 inches) in length. The RG chipbreaker geometry promotes controlled chip formation across a broad range of workpiece materials. Installation and tooling changes are performed by machinists and tooling specialists in production and job shop environments.

This insert is rated for universal primary workpiece material compatibility, covering ISO material groups H, K, M, P, and S. That range includes hardened steels, cast irons, stainless steels, carbon and alloy steels, and heat-resistant superalloys. It is suited for use in CNC machining centers and drilling stations where FINEBEAM series drill bodies are in service. The ISO 13399 standard is referenced for tooling data representation, making integration with CAM and tool management systems straightforward.

Compatibility

Designed for use in ISCAR FINEBEAM series indexable drill bodies that accept NPMT08 style inserts. Verify drill body seat specifications before installation. No additional compatible model numbers were provided in available product data.

Installation Notes

Insert seating and clamping should be performed with the drill body secured and out of the machine spindle. Use the appropriate ISCAR torx or hex key to achieve proper clamping torque per the drill body manufacturer guidelines — do not overtighten or use impact drivers on insert screws. Inspect the insert pocket for chips, debris, or seat damage before installing a new insert. Confirm insert orientation matches the required cutting geometry before returning the tool to service.
