Iscar 5605989 Milling Insert H490 Ankx 1706R15T-FF IC830

Product Description

The ISCAR 5605989 is a solid carbide milling insert carrying the ANSI designation H490 ANKX 1706R15T-FF IC830, designed for use in HELIDO-series face and shoulder milling operations. This double-sided, parallelogram-shaped insert features a negative rake geometry and a helical cutting edge style, with two usable cutting edges per insert. The IC830 grade substrate is finished with an AlTiN and TiN PVD coating classified under ISCAR Sumotec PVD, providing wear and heat resistance suited to interrupted cuts and demanding workpiece materials. The FF chip breaker geometry supports smooth chip flow at moderate to high feed rates. Thickness measures 0.3070 inches and inscribed circle diameter is 0.4610 inches.

This insert is intended for milling steel, stainless steel, superalloys, and titanium — workpiece material codes P, M, and S. It is a right-hand cutting insert and seats via screw clamping in compatible H490 ANK17 series cutter bodies. Typical applications include shoulder milling, face milling, and ramping operations in aerospace, energy, and general machining environments. The maximum depth of cut is 0.0790 inches (2.00 mm), making it suitable for finishing and semi-finishing passes where edge integrity and surface consistency are critical.

Key Features

• Double-sided insert with 2 cutting edges per insert, extending usable tool life
• IC830 grade with AlTiN and TiN PVD coating for wear resistance in steel and superalloy applications
• Helical cutting edge style with FF chip breaker for controlled chip formation
• Negative rake, 85-degree included angle parallelogram geometry for stable clamping
• Right-hand orientation with screw insert-holding method
• Conforms to ANSI and ISO 13399 standards for interchangeability documentation

Compatibility

Designed for use in ISCAR H490 ANK17 series cutter bodies. The ANSI code is H490 ANKX 1706R15T-FF IC830 and the ISO code is H490 ANKX 1706R15T-FF. Verify cutter body pocket geometry and screw size before installation.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before seating or removing inserts. Use the correct torx or hex key specified by the cutter body manufacturer to torque the clamping screw — do not over-tighten, as this can crack the carbide insert. Inspect the pocket seat and clamping screw for wear or debris before installing a fresh insert.
