Iscar 5606805 H400 Rnhu 1004-HP IC830 Milling Insert

Product Description

The ISCAR 5606805 is a round, double-sided milling insert carrying the ANSI designation H400 RNHU 1004-HP IC830. It belongs to ISCAR's HELIDO series and is manufactured from solid carbide with a PVD-applied AlTiN and TiN coating classified under ISCAR's Sumotec PVD system. The insert features a negative rake geometry of 14 degrees, four cutting edges, and an HP chip breaker profile. With a maximum depth of cut of 0.1969 inches (7.50 mm) and an inscribed circle of 0.3620 inches, it is designed for productive face and helical milling operations. Installation requires a screw-holding method and is compatible with H400-10 series cutter bodies. The insert weighs 0.057 pounds.

This insert is engineered for machining steel, stainless steel, superalloys, and titanium, covering ISO material groups P, M, and S. It is suited to demanding applications where thermal and abrasion resistance are critical, including interrupted cuts and high-speed finishing or semi-finishing passes on tough-to-machine alloys. The neutral hand orientation allows use without handedness considerations, and the continuous cutting edge style supports consistent chip formation across the full round profile.

Key Features

• Double-sided insert with four usable cutting edges for extended tool life per insert
• AlTiN and TiN PVD coating (Sumotec PVD) provides high thermal resistance and hardness for steel and superalloy machining
• HP chip breaker geometry optimized for positive chip control in difficult-to-cut materials
• Negative rake angle of 14 degrees delivers strong cutting edge for heavy or interrupted milling cuts
• Round insert shape (360-degree included angle) enables full-profile helical and plunge milling
• Maximum depth of cut of 0.1969 inches (7.50 mm) with a continuous cutting edge length of 0.6299 inches

Compatibility

Designed for use with H400-10 series cutter bodies. ANSI code H400 RNHU 1004-HP IC830; ISO code H400 RNHU 1004-HP. Conforms to ANSI and ISO 13399 standards.

Installation Notes

This insert is installed by a machinist or tooling technician using the screw-holding method standard to H400-10 series cutter bodies. Ensure the machine spindle is fully stopped and locked out before changing inserts. Inspect the pocket seat and clamping screw for debris or wear before seating a new insert. Handle carbide inserts carefully to avoid chipping the cutting edge during installation.
