Iscar 5604421 Ball Nose Milling Insert IC908 0.75 in

Product Description

The ISCAR 5604421 is a solid carbide ball nose milling insert in the BALLPLUS series, designed for high-performance milling operations across a wide range of workpiece materials. Carrying the HCR D.75-QF geometry with an IC908 manufacturer grade, this insert features a TiAlN PVD coating applied over a submicron carbide substrate. It measures 0.75 inches in inscribed circle diameter and 0.183 inches thick, with a 0.375-inch corner radius and a maximum depth of cut of 0.579 inches. The QF chip breaker geometry and positive rake angle promote efficient chip evacuation and reduced cutting forces. Installation and use are intended for qualified machinists and tooling technicians working in professional CNC milling environments.

This insert is suited for milling steel, stainless steel, cast iron, superalloys, titanium, and hard materials. The IC908 grade with PVD TiAlN coating makes it particularly capable in demanding applications involving heat-resistant alloys and hardened workpieces. It is a right-hand, single-sided insert held by screw, compatible with HCM cutter bodies. The BALLPLUS series is commonly used in 3-axis and multi-axis CNC machining centers for profiling, contouring, and finishing passes where a ball nose profile is required.
