Iscar 5550215 Turning Insert Ccmt 3/8 in IC807 Diamond

Product Description

The ISCAR 5550215 is a CCMT-style solid carbide turning insert designed for precision external and internal turning operations on CNC and manual lathes. Manufactured to ISO 13399 standards, this insert features a TiAlN and TiN dual-layer PVD coating applied over a submicron carbide substrate in manufacturer grade IC807. The 80-degree diamond insert shape provides a strong cutting edge geometry with a positive rake angle and a 7-degree relief clearance. The SM chip breaker is engineered for controlled chip formation across a broad range of workpiece materials. Licensed machinists and CNC operators rely on this insert for consistent tool life in medium to finish turning applications.

The 5550215 is suited for universal turning applications across multiple workpiece material groups, including steel, stainless steel, cast iron, high-temperature alloys, and non-ferrous materials, corresponding to ISO material codes P, M, K, S, and H. It fits into the Isoturn series toolholding system and is appropriate for both roughing at shallow depths and finish turning passes where dimensional accuracy is critical. This insert is commonly deployed in job shop, production machining, and maintenance-repair environments.

Key Features

• CCMT insert style with 80-degree diamond shape and positive rake geometry for reduced cutting forces
• IC807 grade submicron solid carbide substrate with TiAlN and TiN PVD dual-layer coating for extended wear resistance
• SM chip breaker controls chip evacuation across universal workpiece material groups
• Screw-type insert holding method ensures secure seating and repeatable indexing
• Compliant with ISO 13399 tooling data standards for integration with CAM and tool management systems
• Maximum depth of cut of 0.0984 inches (2.50 mm) suitable for finish and semi-finish turning passes

Compatibility

Designed for use with ISCAR Isoturn series toolholders accepting CCMT-style inserts with a 3/8-inch inscribed circle. Compatible with ISO material groups H, K, M, P, and S as indicated by the manufacturer.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician with the machine in a full stop and locked-out state before indexing or replacing inserts. Use the appropriate torx or hex key to secure the clamping screw to the toolholder manufacturer's specified method without overtightening the insert seat. Inspect the insert pocket and seating surfaces for chips or debris before seating the new insert. Verify tool offset compensation in the machine controller after each insert index to maintain dimensional accuracy.
