Iscar 5602549 Milling Insert S45MT 1106AP-N IC928 Carbide

Product Description

The ISCAR 5602549 is a solid carbide milling insert designed for high-performance metal removal in demanding machining environments. Cataloged under ISCAR grade IC928 with ANSI designation S45MT 1106AP-N, this insert features a square shape with a 90-degree included angle and four cutting edges. The TiAlN PVD coating provides thermal resistance and wear protection suited to interrupted cuts and high cutting speeds. With a neutral hand orientation and positive rake geometry combined with a T-Land cutting edge style, the insert balances edge strength with cutting efficiency. It is installed via screw-holding and is rated for a maximum depth of cut of 0.2887 inches.

This insert is engineered for milling steel, stainless steel, superalloys, and titanium, corresponding to ISO material codes P, M, and S. It belongs to the CHAMMILL series, which targets square-shoulder and face milling operations across general-purpose and precision machining applications. Typical users are CNC machinists and tool-and-die professionals running vertical or horizontal machining centers where consistent edge geometry and coating durability at elevated temperatures are critical. The N chip breaker geometry suits a range of feed and depth conditions across these workpiece materials.

Key Features

• Square insert shape with 90-degree included angle and four usable cutting edges
• Positive rake geometry with T-Land cutting edge style for balanced strength and shear action
• Neutral hand orientation — compatible with both right- and left-hand tooling setups
• Maximum depth of cut of 0.2887 inches with cutting edge effective length of 0.4331 inches
• Single-sided insert with screw-holding method; conforms to ANSI and ISO 13399 standards

Compatibility

Designed as an OEM-style replacement or direct-use insert for ISCAR CHAMMILL series milling bodies that accept S45MT 1106-style square inserts with screw-holding. Verify toolholder seat geometry and insert size code 1106 compatibility before installation.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. Ensure the machine spindle is fully stopped and locked out before changing inserts. Use the correct torque screwdriver specified by the toolholder manufacturer for the clamping screw — do not overtighten, as this can crack the carbide substrate. Inspect the insert pocket seating surface for chips or debris before seating the new insert to ensure proper registration and edge geometry.
