Iscar 5690318 Milling Insert Sekt 1204AFR-HM IC950 Tialn

Product Description

The ISCAR 5690318 is a solid carbide milling insert designated by ISO code SEKT 1204AFR-HM in grade IC950. This square-style insert is coated with TiAlN via a PVD process, delivering wear resistance suited to interrupted and continuous milling cuts. It carries four usable cutting edges, a positive rake geometry, and a 20-degree relief angle, which collectively reduce cutting forces and heat buildup during operation. The HM chip breaker geometry promotes controlled chip evacuation. Thickness measures 0.2030 inches and the inscribed circle diameter is 0.5000 inches. Maximum depth of cut reaches 0.2520 inches. The insert is held in place by a screw-lock mounting method.

This insert is engineered for milling steel and cast iron workpiece materials, aligning with ISO material groups P and K. It is well suited to face milling, shoulder milling, and related operations in both production shop and job-shop environments. Typical applications include roughing and semi-finishing passes on ferrous components where tool life consistency and edge stability under moderate to high feed rates are priorities. The insert is part of the ISCARMILL series and is noted as compatible with cutter series F92ST and F45ST.

Key Features

• IC950 grade solid carbide with TiAlN PVD coating for extended wear life in steel and cast iron cutting
• Square SEKT insert shape with 90-degree included angle and positive rake for reduced cutting forces
• Four cutting edges per insert to maximize cost efficiency per edge
• HM chip breaker geometry for controlled chip formation and evacuation
• 20-degree relief angle supports clean edge engagement and reduced flank wear
• Screw-lock insert holding method for secure, repeatable seating in compatible cutter bodies

Compatibility

Compatible with ISCARMILL cutter series F92ST and F45ST. ANSI equivalent code is SEKT 43AFR-HM IC950. Conforms to ANSI and ISO 13399 standards.

Installation Notes

Installation is performed by machining technicians or toolroom personnel using the screw-lock mounting system; use the appropriate Torx or hex key specified by the cutter body manufacturer to seat the insert securely. Always power down and lock out the machine spindle before changing inserts. Inspect the cutter body pocket and seating surface for chips or damage before installing a fresh insert. Neutral hand orientation allows use in standard right-hand cutter configurations without modification.
