CNMG120404 T9215 ISO turning insert, rhombic 80° for turning by Tungaloy

The CNMG120404 T9215 is an ISO‑standard rhombic turning insert designed for external and internal turning, offering a robust CVD‑coated carbide grade for productive machining of medium steel.

• CVD‑coated carbide T9215
• Rhombic 80° geometry
• 0.4 mm corner radius
• Double‑sided chipbreaker

Improved productivity for medium‑steel turning

The CVD‑coated T9215 grade delivers a balance of wear resistance and fracture toughness that favours sustained production runs. As a result, cycle times can be shortened through higher cutting speeds and extended tool life, which reduces the frequency of index changes and downtime. This grade is optimised for continuous to light interrupted cuts, meaning stable performance when machining shafts, journals and turned bores in medium‑strength steels. The technical combination of coating and substrate translates directly into lower cost per component in volume production.

Seamless integration with ISO toolholders reduces setup time

Designed to ISO dimensions, the rhombic 80° geometry and standard clamping interfaces mean the insert fits a wide range of external holders and boring bars without special adaptions. Compatibility is determined by the insert form, relief angle, tolerance class, clamping method, size and plate thickness, so predictable fitment shortens setup and changeover. Clear specification of these parameters enables process planners to standardise tool inventories and simplify holder selection, which in turn improves machine uptime and repeatability in batch production.

Reliable chip control and secure clamping for consistent surfaces

The double‑sided chipbreaker geometry helps maintain controlled chip formation and evacuation, supporting consistent surface finishes and safer swarf handling. The insert’s 0.4 mm corner radius provides a compromise between edge strength and profile detail, useful for finishing passes or where dimensional control matters. A cylindrical hole ensures secure clamping and repeatable seat positioning, contributing to steady cutting forces and less vibration. Together, these design elements support accurate turning results and consistent component quality.
