Iscar 5600135 Milling Insert Sekn 1203AFFN IC20 Carbide

Product Description

The ISCAR 5600135 is a solid carbide milling insert carrying the ISO designation SEKN 1203AFFN and manufacturer grade IC20. Designed for use in indexable milling cutters, this square-shaped, single-sided insert features a bright uncoated finish and a positive rake geometry with a sharp cutting edge style. It measures 0.5 inches in length and width with a thickness of 0.125 inches, and delivers a maximum depth of cut of 0.256 inches (6.50 mm). The flat-top chip breaker and 20-degree relief angle support efficient chip evacuation across a range of workpiece materials. Licensed machinists and CNC tooling technicians install this insert in production and job-shop milling applications.

This insert is suited for milling stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. Its neutral hand orientation allows flexible positioning in compatible toolholders. The ISCAR 5600135 is part of the ISCARMILL series and is compatible with the F45E cutter series. It conforms to ANSI and ISO 13399 standards, with the ANSI code SEK 42AFFN IC20, making it straightforward to cross-reference in tooling catalogs. Typical applications include face milling, shoulder milling, and general-purpose material removal where consistent edge geometry is required across multi-material production runs.

Key Features

• Solid carbide construction with bright uncoated (IC20 grade) finish for direct material contact performance
• Square insert shape with 4 cutting edges, maximizing index life per insert
• Positive rake and 20-degree relief angle reduce cutting forces on difficult-to-machine materials
• Sharp cutting edge style with flat-top chip breaker for clean chip evacuation
• Maximum depth of cut of 0.256 inches (6.50 mm) supports aggressive stock removal passes
• Conforms to ANSI and ISO 13399 standards for broad toolholder cross-referencing

Compatibility

Compatible with the F45E cutter series within the ISCARMILL platform. Conforms to ANSI code SEK 42AFFN IC20 and ISO code SEKN 1203AFFN, enabling cross-reference with any toolholder specifying these designations per ANSI and ISO 13399 standards.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians following machine lockout and spindle stop procedures before indexing or replacing inserts. Use the appropriate torque wrench and clamp hardware specified by the cutter body manufacturer to secure the insert via the clamp holding method. Inspect the insert seat and clamp for wear or debris before seating a new insert. Do not exceed the maximum depth of cut rating for the insert or cutter body to avoid insert fracture or toolholder damage.
