CNMG 120408 T9215 – CNMG indexable turning insert by Tungaloy for medium steel turning

A CNMG120408 T9215 indexable turning insert designed for external and internal turning, delivering high productivity in continuous to lightly interrupted cuts while matching standard ISO toolholders.

• CVD-coated carbide for high wear resistance
• ISO-standard rhombic insert for universal holders
• Optimised for medium steel machining
• Double-sided with 0° relief angle

Enhanced productivity through robust coating and grade selection

The CVD-coated carbide grade T9215 offers a balanced combination of wear resistance and fracture toughness, which is intended for the efficient machining of medium steels. The coating process deposits thin, dense layers that reduce flank and crater wear, so tool life can be extended under the recommended operating conditions. By selecting a suitable chipbreaker and matching the grade to the workpiece stability and machining type, productive cutting speeds can be achieved while maintaining consistent surface quality. This balance supports longer running times and fewer insert changes, improving overall shop throughput.

Secure clamping and ISO compatibility for predictable results

The rhombic CNMG geometry with an 80° lead angle and 0° relief is manufactured to ISO dimensions, so compatibility with ISO-designated holders is determined by the insert form, clearance angle, tolerance class, fastening and thickness. The insert is made double-sided and features a cylindrical mounting hole, enabling reliable seating and repeatable positioning. Such standardisation simplifies inventory and tool assembly: inserts are interchangeable between matching external holders and boring bars, and clamping systems are able to generate consistent cutting edge location and repeatable run-out for predictable part quality.

Practical guidance for application and edge performance

Designed primarily for turning operations on medium steel, the insert performs well in continuous and slightly interrupted cuts when used with a stable tool setup and appropriate chip control. The small corner radius and the specified edge preparation provide a balance between edge strength and the ability to produce a fine surface finish. Given the double-sided design and robust substrate, insert changes are infrequent in well-optimised processes, which reduces downtime. For best results, pair the insert with a holder that matches the ISO form and ensure correct clamping torque so that the cutting edge is secure and vibration is minimised.

FAQ

What materials is this insert best suited for?
The CNMG120408 T9215 insert is optimised for medium steel machining; the Tungaloy T9215 grade combines wear resistance and toughness for productive turning.

Is the insert compatible with standard ISO holders?
Yes, the insert is manufactured to ISO dimensions and will fit holders that accept CNMG geometry provided form, clearance and thickness are matched.

How is the insert mounted in the toolholder?
Mounting is achieved via the cylindrical hole and the standard clamping system for CNMG inserts; correct clamping and a matching underlay ensure repeatable positioning.

Can this insert be indexed to use the second cutting edge?
The insert is double-sided and can be indexed to present a fresh cutting edge; proper handling and removal of any built-up deposits is advised before indexing.

What advantages does the CVD coating provide?
The CVD-coated carbide substrate reduces flank and crater wear, supporting higher cutting speeds and longer tool life in suitable steel-turning applications.
