Iscar 5604291 Ball Nose Milling Insert IC908 Tialn

Product Description

The ISCAR 5604291 is a solid carbide ball nose milling insert from the BALLPLUS series, designed for high-performance milling operations across a broad range of workpiece materials. Manufactured to ANSI and ISO 13399 standards, this insert carries the IC908 grade designation, a submicron carbide substrate with a PVD-applied TiAlN coating. The insert measures 1 inch in inscribed circle diameter and 0.212 inches thick, with a 0.5-inch corner radius and two cutting edges. The QF chip breaker geometry and positive rake angle promote efficient chip evacuation and reduced cutting forces during profiling and contouring passes.

This insert is suited for milling steel, stainless steel, cast iron, superalloys, titanium, and hard materials in both roughing and finishing applications. The right-hand cutting geometry and screw-holding method make it a practical fit for standard BALLPLUS tooling setups in production machining environments. Maximum depth of cut reaches 0.67 inches, making it capable of moderate-depth profiling passes in CNC milling centers handling both general and difficult-to-machine materials.

Key Features

• IC908 submicron carbide grade with PVD TiAlN coating for wear resistance across P, M, K, S, and H material classes
• Ball nose geometry with 0.5-inch corner radius for contouring, profiling, and 3D surface milling
• QF chip breaker with positive rake for efficient chip control and lower cutting forces
• Two honed cutting edges, single-sided, right-hand orientation
• Maximum depth of cut of 0.67 inches with effective cutting edge length of 0.67 inches
• Compliant with ANSI and ISO 13399 insert standards

Compatibility

Designed for use with HCM cutter series toolholders. Compatible insert style is HBR. Insert holding method is screw-type. Confirm toolholder pocket specifications against ANSI code HBR D1.0-QF IC908 and ISO code HBR D1.0-QF before installation.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the spindle is fully stopped and the machine is in a locked-out, tagged-out state before seating or replacing inserts. Use the correct torx or hex key to the toolholder manufacturer's specified seating procedure when driving the clamping screw. Inspect the pocket seat for chips or debris before installing the insert to avoid seating errors that can lead to premature edge failure.
