Iscar 5606808 Milling Insert H400 Rnhu 1606-HP IC830

Product Description

The ISCAR 5606808 is a round milling insert from the HELIDO series, designed for use in milling cutters compatible with the H400-16 cutter series. It carries the ANSI designation H400 RNHU 1606-HP and is manufactured from solid carbide with an AlTiN and TiN coating applied via PVD under the Sumotec PVD coating classification. The insert features a double-sided configuration, a neutral hand, negative rake geometry with a 14-degree rake angle, and four cutting edges. Maximum depth of cut is 0.315 inches (8.00 mm). The HP chip breaker geometry targets aggressive material removal in demanding applications. Installation is performed by licensed machinists or tooling technicians using a screw-holding method.

This insert is suited for milling operations on steel, stainless steel, superalloys, and titanium workpieces, corresponding to ISO material codes P, M, and S. It fits into tool bodies within the H400-16 cutter series and is appropriate for both roughing and semi-finishing passes where consistent edge life and chip control are required. The continuous cutting edge style supports stable, uninterrupted engagement with the workpiece. Applications span general machining shops and production environments running demanding ferrous and non-ferrous alloy components.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before removing or seating inserts. Use the correct torx or hex key specified by the tool body manufacturer to secure the clamping screw — do not overtighten. Inspect the insert seat and clamping screw for wear or debris before installing a new insert.
