Iscar 5601748 Milling Insert Semt 1204AF-R-HS IC328 Carbide

Product Description

The ISCAR 5601748 is a solid carbide milling insert carrying ISO designation SEMT 1204AF-R-HS in grade IC328. It is a single-sided, square-shaped insert designed for use in positive-rake milling operations. The PVD-applied TiCN coating delivers wear resistance and edge toughness suited to demanding interrupted and continuous cuts. With four usable cutting edges, a 20-degree relief angle, and a honed cutting edge style, this insert is engineered for productive material removal in steel, stainless steel, superalloys, and titanium applications. It is held in the cutter body by a screw-clamp method and is intended for installation by machinists and tooling technicians in CNC milling setups.

This insert is part of the ISOSHRED series and is compatible with the F45ST cutter body family. It targets primary workpiece materials classified under ISO material codes P, M, and S — covering carbon and alloy steels, stainless steels, and high-temperature superalloys including titanium. The HS chip breaker geometry supports stable chip evacuation across these material groups. Typical applications include face milling, shoulder milling, and multi-directional ramping where a positive cutting geometry and high edge security are required in production or job-shop environments.

Key Features

• IC328 grade with PVD TiCN coating for extended tool life in steel and superalloy cutting
• Four cutting edges per insert for reduced cost-per-edge
• Positive rake geometry with 20-degree relief angle reduces cutting forces
• HS chip breaker promotes controlled chip formation across material grades P, M, and S
• Honed cutting edge style improves edge stability and reduces micro-chipping
• Right-hand orientation, screw-held mounting for secure seating in compatible toolholders
• Conforms to ANSI and ISO 13399 standards for interchangeability documentation

Compatibility

Designed for use with the ISCAR F45ST cutter series. ANSI equivalent designation is SEMT 43AF-R-HS IC328. Suitable for machining steel, stainless steel, superalloys, and titanium workpieces per ISO material codes P, M, and S.

Installation Notes

Installation and indexing should be performed by a qualified machinist or tooling technician with the spindle fully stopped and the machine locked out. Use the correct torx or hex key specified by the cutter body manufacturer when seating the screw clamp — do not overtighten, as this can fracture the insert. Inspect the insert pocket and seating surface for chips or debris before seating a new insert. Always verify runout and axial position after indexing before resuming cutting operations.
