Iscar 5602003 Milling Insert Semt 12T3AFTN-76 IC908

Product Description

The ISCAR 5602003 is a square milling insert in the ISCARMILL series, designated SEMT 12T3AFTN-76 with IC908 grade solid carbide construction. It features a Physical Vapor Deposition (PVD) TiAlN coating applied over a submicron carbide substrate, delivering hardness and thermal resistance in demanding milling operations. The insert measures 0.5177 inches in length and width, with a thickness of 0.146 inches and an inscribed circle of 0.518 inches. It carries four cutting edges on a single-sided, neutral-hand geometry with a positive rake and T-land cutting edge style at a 90-degree included angle. HVAC, mechanical, and industrial machinists rely on this insert for high-productivity face and shoulder milling applications.

This insert is suited for milling steel, stainless steel, cast iron, superalloys, titanium, and hard materials, covering ISO material codes P, M, K, S, and H. It is designed for use in ISCARMILL F45ST cutter bodies. The maximum depth of cut reaches 6.50 mm (0.256 inches), and the chip breaker designation is 76, optimized for controlled chip formation across a broad range of workpiece materials. It is held in the cutter body by a screw-clamp method, standard for SEMT-style inserts in indexable milling tooling.

Key Features

• IC908 submicron solid carbide grade with PVD TiAlN coating for wear and heat resistance
• Four cutting edges per insert for extended tool economy
• Positive rake and T-land edge style reduce cutting forces and improve edge stability
• Maximum depth of cut of 0.256 inches (6.50 mm) for productive material removal
• Neutral hand orientation fits standard F45ST cutter body configurations
• Compliant with ANSI and ISO 13399 standards for insert identification and interchangeability

Compatibility

Designed for use with ISCARMILL F45ST cutter body series. Conforms to ANSI code SEMT 12T3AFTN-76 IC908 and ISO code SEMT 12T3AFTN-76 per ISO 13399.

Installation Notes

Installation is performed by a machinist or toolroom technician. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct Torx or hex key driver specified for the cutter body's screw-clamp system and avoid over-tightening, which can crack the insert. Inspect the cutter body pocket and seating surfaces for chips or wear before seating a new insert.
