Iscar 5600745 Milling Insert Sekt 43AFR-HM IC28 Carbide

Product Description

The ISCAR 5600745 is a solid carbide milling insert carrying the ANSI designation SEKT 43AFR-HM in grade IC28. It is a square-shaped, single-sided insert designed for face and shoulder milling operations on non-ferrous metals. The insert features a positive rake angle of 15 degrees, a relief angle of 20 degrees, and an HM chip breaker geometry. With four usable cutting edges, a 0.5 inch inscribed circle, and a maximum depth of cut of 0.252 inches (6.40 mm), this insert is suited for high-productivity light-to-medium milling passes. It is held in the cutter body via screw clamping and is compatible with the ISCARMILL series tool bodies.

This insert is intended for milling applications where the primary workpiece material is non-ferrous metal, including aluminum alloys and other N-code materials per ISO classification. It is used in both production shop and maintenance environments by machinists and CNC operators running face mills, shoulder mills, and similar indexable milling cutters. The neutral hand orientation allows fitment in standard square-pocket tool bodies. The HM chip breaker promotes efficient chip evacuation and surface finish control in non-ferrous cuts.

Key Features

• Solid carbide construction, uncoated bright finish — grade IC28 optimized for non-ferrous metal cutting
• Positive 15-degree rake angle and 20-degree relief angle reduce cutting forces on aluminum and similar materials
• Four cutting edges per insert for extended tool life per unit cost
• HM chip breaker geometry supports controlled chip flow and consistent surface finish
• Maximum depth of cut of 0.252 inches (6.40 mm) with a 0.508 inch effective cutting edge length
• Screw-held, single-sided design for secure seating in compatible milling bodies

Compatibility

Designed for use with ISCARMILL cutter series F92ST and F45ST tool bodies. ISO equivalent designation is SEKT 1204AFR-HM. Conforms to ANSI and ISO 13399 standards.

Installation Notes

Installation is performed by machinists or tooling technicians. Before indexing or replacing inserts, the machine spindle must be fully powered down and locked out per applicable safety procedures. Use the appropriate Torx or hex key as specified by the cutter body manufacturer to seat and torque the clamping screw — do not overtighten. Inspect the insert pocket seating surface for chips or debris before installing a new insert to ensure proper contact and runout control.
