CNMG120412 T9215 turning insert by Tungaloy

A CNMG120412 T9215 is an ISO‑standard rhombic turning insert designed for external and internal turning, combining CVD‑coated carbide performance with a robust double‑sided chipbreaker.

• CVD‑coated carbide grade T9215 for medium steel
• Rhombic 80° insert, size 12 and 4.76 mm thickness
• 1.2 mm corner radius for stable cutting
• Double‑sided chipbreaker with cylindrical hole

Higher throughput through wear‑resistant grade and stable geometry

The CVD‑coated grade T9215 is engineered to balance high wear resistance with fracture toughness, making it particularly effective in the machining of medium steel under continuous or slightly interrupted cuts. This combination reduces unscheduled tool changes and supports predictable tool life, which translates into lower cycle costs and improved throughput. The coating enhances thermal and abrasive resistance, while the substrate toughness helps to withstand edge shocks and maintain dimensional stability over longer production runs.

Reliable cutting performance from precise insert geometry

The rhombic 80° geometry and 1.2 mm corner radius deliver a compromise between strength and finishing capability that suits both roughing and finishing passes. The 12 size and 4.76 mm plate thickness provide a stable interface with compatible holders, reducing vibration and promoting consistent surface quality. The zero clearance design ensures the insert seats precisely in the pocket; when paired with an appropriate holder, this results in improved repeatability and reduced set‑up time for batch production.

Seamless integration into ISO‑based tooling systems

As an ISO turning insert, the component fits into established systems comprising a matching outer holder or boring bar, backing/clamping set and fastening screws. The cylindrical hole and standard tolerances ensure secure clamping and simple indexation, while the double‑sided layout offers two usable edges per side before replacement, optimising material usage. Compatibility depends on form, clearance angle, tolerance class, fixation, size and thickness; selecting the correct holder and clamping set is essential for achieving the stated performance.

Targeted chip control and application guidance for turning

The double‑sided chipbreaker is configured to handle chip formation for medium steel, supporting efficient evacuation and stable cutting forces. For best results, choose the chipbreaker style and grade to match the workpiece, feed and depth of cut — this promotes consistent chip control and a superior surface finish. Typical applications include external and internal turning where a balance of productivity and edge security is required; the insert is a practical choice for shops aiming to combine robust performance with predictable results.
