Iscar 5601809 Milling Insert Semt 43AFTN-76 IC328 Carbide

Product Description

The ISCAR 5601809 is a solid carbide milling insert carrying the ANSI designation SEMT 43AFTN-76 in grade IC328. It is a single-sided, square-shaped insert with four cutting edges, a positive rake geometry, and a T-Land cutting edge style. The insert is PVD-coated with TiCN for thermal stability and edge wear resistance. At 0.187 inches thick and 0.500 inches wide, it is screw-held and designed for use in face and shoulder milling operations requiring precise depth of cut control up to 0.256 inches. Grade IC328 is optimized for steel, stainless steel, superalloys, and titanium work materials.

This insert fits into the ISCARMILL F45ST cutter series and is suited for general milling applications in production and job-shop environments. Typical end users include CNC machinists and tool-and-die shops working with ISO material groups P, M, and S. The 90-degree included angle and neutral hand orientation make this insert compatible with a wide range of face milling and shoulder milling setups. Chip breaker style 76 is designed to manage chip flow in moderate to aggressive cuts on the listed workpiece materials.

Key Features

• PVD TiCN coating provides wear resistance in steel and stainless steel applications
• Four usable cutting edges per insert extend tool life and reduce per-edge cost
• T-Land cutting edge style improves edge strength and reduces chipping under interrupted cuts
• Positive rake geometry lowers cutting forces on difficult materials including superalloys and titanium
• Screw-clamping insert holding method ensures repeatable seating and accurate depth of cut
• Dual-standard compliance with ANSI and ISO 13399 simplifies tool management and documentation

Compatibility

Designed for use in the ISCARMILL F45ST cutter series. ISO code equivalent is SEMT 1204AFTN-76. Compatible with material grades C2, C3, C5, and C6 per ANSI classification. Primary workpiece material codes P, M, and S cover steel, stainless steel, superalloys, and titanium.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Ensure the cutter body is fully de-energized and the machine spindle is locked before changing inserts. Use the correct torx or hex key to seat the screw to the cutter manufacturer's specified interface requirements. Inspect the insert pocket for debris or wear before seating a new insert to maintain proper clamping and runout.
