Iscar 5603413 Milling Insert Sekt 1204AFR-HM IC4050

Product Description

The ISCAR 5603413 is a solid carbide coated square milling insert designated under ISO code SEKT 1204AFR-HM in grade IC4050. It is a single-sided, neutral-hand insert engineered for face and shoulder milling operations on ferrous workpiece materials. The IC4050 grade features a multilayer MTCVD coating of TiCN, Al2O3, and TiN, delivering thermal resistance and wear performance suited to interrupted and continuous cuts. With 4 usable cutting edges, a 15-degree rake angle, a 20-degree relief angle, and a honed cutting edge style, this insert is installed by machinists and toolroom technicians running ISCARMILL-series cutter bodies.

This insert is intended for milling steel, stainless steel, and cast iron in production machining environments. The positive rake geometry and HM chip breaker geometry reduce cutting forces on medium to heavy feeds. Compatible cutter series listed by ISCAR include the F92ST and F45ST shoulder and face mill bodies. The insert is secured by a screw-clamping method. It suits both general machining shops and high-volume production lines where consistent tool life and edge repeatability across 4 indexes are priorities.

Key Features

• Solid carbide substrate with MTCVD multilayer coating: TiCN, Al2O3, and TiN for extended wear resistance
• 4 cutting edges per insert with neutral hand orientation, maximizing cost-per-edge value
• Positive rake angle of 15 degrees reduces cutting forces on steel and stainless steel
• HM chip breaker design controls chip formation on medium to heavy feed rates
• Maximum depth of cut of 0.252 inches (6.40 mm) for full-depth shoulder passes
• Compliant with ANSI and ISO 13399 tooling data standards

Compatibility

Designed for use in ISCARMILL cutter bodies F92ST and F45ST. Insert conforms to ANSI code SEKT 43AFR-HM IC4050 and ISO code SEKT 1204AFR-HM. Primary workpiece material codes are P (Steel), M (Stainless Steel), and K (Cast Iron).

Installation Notes

Installation is performed by a machinist or toolroom technician following the cutter body manufacturer torque specifications for the screw-clamp seat. Power down and lock out the spindle before indexing or replacing inserts. Inspect the insert pocket seat and clamping screw for wear or debris before seating a new insert. Confirm proper seating before resuming cutting to avoid insert rocking or premature edge failure.
