Iscar 5602918 Seht 1204AFN IC928 Milling Insert Square

Product Description

The ISCAR 5602918 is a square milling insert conforming to ISO designation SEHT 1204AFN in manufacturer grade IC928. The insert is manufactured from solid carbide and finished with a TiAlN coating applied via PVD process, producing a sharp cutting edge suited to high-speed milling of difficult materials. It features a positive rake geometry with a 20-degree relief angle and the AFN chip breaker profile. The inscribed circle measures 0.500 inches, thickness is 0.187 inches, and the maximum depth of cut reaches 0.256 inches (6.50 mm). With four usable cutting edges per insert, it delivers consistent tool economy across production runs. The insert is held in place by screw-type clamping.

This insert is intended for face milling, shoulder milling, and general-purpose milling applications on steel, stainless steel, superalloys, and titanium workpieces. It belongs to the ISCARMILL series and is compatible with the F45ST cutter series. The neutral hand orientation makes it appropriate for a range of toolholder configurations. Typical applications include roughing and semi-finishing operations in job shop, aerospace, and general machining environments where consistent performance on ISO material groups P, M, and S is required.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Disengage spindle power and confirm the machine is in a safe, locked-out state before changing inserts. Use the appropriate Torx or hex key to seat the clamping screw to the toolholder manufacturer's specification. Inspect the insert pocket and seating surfaces for chips or debris before installing a new insert to ensure proper seating and avoid premature edge failure.
