CNMG 120404 T9215 turning insert (ISO CNMG 120404) by Tungaloy — CVD-coated carbide, 80° rhombic

The CNMG120404 T9215 Tungaloy insert is an ISO-standard rhombic turning insert designed for external and internal turning, optimised for medium steel machining and continuous to lightly interrupted cuts.

• CVD-coated carbide (T9215)
• Optimised for medium steel machining
• Double-sided chipbreaker for chip control
• ISO CNMG 80° rhombic form, 0° clearance angle

Boosted productivity through durable coating and grade selection

The combination of a CVD coating and a wear-resistant carbide substrate in grade T9215 provides a reliable balance between wear resistance and breakage resistance, making the insert particularly suited to repetitive production. The result is increased productivity with fewer indexings and predictable tool life, which supports stable batch manufacturing and shorter process downtime. For process planners this means fewer interruptions and more consistent cycle times when machining medium-strength steels.

Secure chip control and process stability for everyday turning

Equipped with a double-sided chipbreaker, the insert ensures effective chip control across a range of cutting conditions. The controlled chip formation reduces the risk of tangling and improves surface consistency, which benefits both automated and manual setups. The rhombic ISO CNMG geometry with an 80° included angle provides a robust cutting edge for external and internal turning, while the 0° clearance assists in maintaining a steady contact zone during continuous cuts.

Fast integration with standard holders and straightforward mounting

Compatibility to toolholders depends on form, clearance angle, tolerance class, fastening method, size and thickness; this insert matches common ISO holders thanks to the CNMG form and the cylindrical hole for secure fastening. The insert thickness of 4.76 mm and an effective size of 12 mm ease selection of appropriate clamping sets and replacement screws. The standardised interface reduces setup time and supports quick changeovers in production environments.

Practical selection guidance for medium steel applications

Grade T9215 is recommended as a first choice for medium steel machining because it combines good wear behaviour with resistance to chipping under continuous to slightly interrupted cuts. The small corner radius (0.4 mm) offers a balance between edge strength and surface finish, making the insert suitable for finishing and general turning tasks where a reliable surface quality and steady productivity are required. When in doubt about feed and speed, consulting cutting-data tables specific to the grade and machine rigidity will maximise tool life.
