Iscar 4818309 Indexable Drill Insert NPHT06RG IC908

Product Description

The ISCAR 4818309 is a solid carbide indexable drill insert designed for use in FINEBEAM series indexable drills. It carries the NPHT insert style with an RG chipbreaker geometry and is manufactured in grade IC908, a PVD-coated carbide grade with a TiAlN coating. The insert measures 0.236 inches in width and 0.315 inches in length, conforming to insert size code 06. Weighing approximately 0.05 pounds, this insert is intended for precision drilling operations performed by machining professionals and CNC operators working across a range of workpiece materials.

The IC908 grade with TiAlN PVD coating is rated for universal application across multiple ISO material groups, including ferrous metals, hardened materials, cast irons, stainless steels, and heat-resistant superalloys, corresponding to ISO material codes H, K, M, P, and S. This makes the 4818309 a versatile option for shops running varied materials on the same tooling platform. It is suited to both general-purpose production drilling and demanding applications where tool life and edge stability are priorities in a FINEBEAM drill body.

Compatibility

Designed for use in ISCAR FINEBEAM series indexable drill bodies that accept NPHT style inserts at insert size code 06. Confirm toolholder seat geometry and clamping requirements against ISCAR FINEBEAM toolholder documentation before ordering.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine powered down and locked out before any insert change. Use the correct torx or hex key as specified by the FINEBEAM toolholder documentation to seat and clamp the insert; do not overtighten or substitute non-specified fasteners. Inspect the insert pocket and clamping screw for wear or damage before seating a new insert. Follow the toolholder manufacturer guidelines for recommended cutting parameters when setting up a new insert run.
