Iscar 5550213 Ccmt 2-2-SM IC807 Carbide Turning Insert

Product Description

The ISCAR 5550213 is a solid carbide turning insert designed for precision external and internal turning operations on CNC lathes and turning centers. It carries the ISO designation CCMT 2-2-SM and is manufactured to the IC807 grade, a submicron carbide substrate with a PVD-applied TiN and TiAlN multilayer coating for wear resistance and thermal stability. The 80-degree diamond (C) insert shape provides a strong cutting edge with a 7-degree relief angle and a positive rake geometry. Corner radius measures 0.031 inches, and the inscribed circle diameter is 0.25 inches. Installation is handled by licensed machinists and CNC operators working with indexable tooling systems.

This insert is suited for universal workpiece material applications, covering ISO material groups H, K, M, P, and S, making it adaptable across steel, stainless, cast iron, non-ferrous, and superalloy turning. The SM chip breaker geometry promotes effective chip control during finishing and semi-finishing passes. Maximum depth of cut reaches 0.098 inches (2.49 mm). The Isoturn series designation identifies it as part of ISCARs standard single-sided turning insert line. Typical applications include shaft turning, facing, and contour turning in production and job-shop environments.

Key Features

• IC807 submicron carbide grade with PVD TiN and TiAlN coating for extended tool life
• CCMT insert style with 80-degree diamond shape and positive rake for reduced cutting forces
• SM chip breaker optimized for chip control in finishing and semi-finishing cuts
• 7-degree relief angle (clearance code C) with tolerance code M for consistent seating
• Screw-clamp insert holding method for secure, repeatable indexing
• Universal material compatibility across ISO groups H, K, M, P, and S

Compatibility

Designed as an OEM-style replacement insert for indexable turning toolholders accepting CCMT-style inserts with a 0.25-inch inscribed circle. Conforms to ISO 13399 standards for interchangeability with compatible Isoturn series toolholders.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torx or hex key to torque the clamping screw to the toolholder specification — do not overtighten, as this can crack the insert. Inspect the insert seat and screw for wear or debris before seating a new insert to ensure proper contact and runout.
