Iscar 5600571 Milling Insert Sekt 43AFR-HM IC520M Carbide

Product Description

The ISCAR 5600571 is a square-style indexable milling insert designed for face and shoulder milling operations on steel, stainless steel, and cast iron. Manufactured from solid carbide with a CVD-applied TiCN coating, this insert carries the manufacturer grade IC520M and the ANSI designation SEKT 43AFR-HM IC520M. It features a positive rake angle of 15 degrees, a relief angle of 20 degrees, and a honed cutting edge style. With four usable cutting edges and a neutral hand orientation, it delivers consistent performance across high-volume production runs. Licensed machinists and CNC tooling specialists install this type of insert on indexable milling cutter bodies.

This insert is rated for primary workpiece materials including steel (P), stainless steel (M), and cast iron (K). It belongs to ISCAR's ISCARMILL series and is confirmed compatible with the F92ST and F45ST cutter series. The HM chip breaker geometry supports stable chip control at the cutting depths this insert is designed to handle, making it well suited for roughing and semi-finishing passes on machining centers in both job shop and production environments. It meets ANSI and ISO 13399 standards, with an ISO code of SEKT 1204AFR-HM.

Key Features

• Solid carbide substrate with CVD TiCN coating for wear resistance on ferrous materials
• Four cutting edges per insert — single-sided, neutral hand orientation
• Positive rake angle (15 degrees) reduces cutting forces on steel and stainless steel
• HM chip breaker geometry for controlled chip formation during milling
• Maximum depth of cut: 0.252 inches (6.40 mm)
• Compliant with ANSI and ISO 13399 insert identification standards

Compatibility

Confirmed compatible with ISCAR ISCARMILL cutter series F92ST and F45ST. ANSI code: SEKT 43AFR-HM IC520M. ISO code: SEKT 1204AFR-HM.

Installation Notes

This insert is held in the cutter body by a screw-clamp method — use the torque specification published in the ISCAR cutter body documentation for the applicable cutter series. Power down and lock out the spindle before indexing or replacing inserts. Inspect the cutter body pocket and seating surfaces for debris or damage before seating a new insert. Insert indexing and tooling setup should be performed by qualified machinists or CNC tooling personnel following shop safety procedures.
