CNMG120416 T9225 CNMG ISO 120416 Turning Insert by Tungaloy — CVD-coated carbide, universal grade

A CNMG120416 T9225 indexable turning insert engineered for medium to heavy steel turning, offering a combination of toughness and wear resistance suited to interrupted cuts and variable engagement conditions

• CVD-coated carbide for enhanced wear resistance
• Universal T9225 grade for medium to heavy steel
• Rhombic CNMG shape with 80° cutting angle
• Double-sided insert with cylindrical hole

Consistent cutting performance for medium to heavy turning

The CVD-coated carbide composition of this indexable plate delivers a balance between toughness and abrasion resistance that is advantageous when machining steels under varying engagement. The selected grade is optimised to resist chipping during light interruptions while maintaining edge life during sustained cuts. For production environments, this results in fewer unplanned tool changes and a steadier process window, improving overall machine uptimes and effective productivity.

ISO form and precise dimensions for reliable holder compatibility

Built to ISO standards, the ISO CNMG120416 geometry simplifies tool planning and holder procurement across workshops. Key dimensions include a 12 mm inscribed circle, plate thickness of 4.76 mm and a corner radius of 1.6 mm, with a rhombic form and a nominal cutting angle of 80°. The insert is supplied with a cylindrical hole for secure fastening and a 0° relief angle. These standardised measurements allow predictable clamping behaviour and repeatable positioning in compatible external holders or boring bars.

Improved chip control and process stability

The double-sided design combined with a dedicated chipbreaker pattern supports controlled chip formation in a range of cutting conditions. Stable chip control reduces surface defects and minimises the risk of chip entanglement, which is especially important in automated or lights-out operations. The universal nature of the grade means operators benefit from a single inventory item that covers several turning tasks, lowering tooling complexity while maintaining component quality.

Practical integration and handling for production settings

Integration into existing tool systems follows the usual ISO indexable insert workflow: select a compatible external holder or boring bar considering form, relief angle, tolerance class, fastening method and plate thickness. A well-matched system — including the appropriate clamp set and replacement screws — ensures secure fastening and repeatable tool offsets. The insert’s construction supports predictable tool life and stable surface finishes, making it suitable for job shops and production lines seeking efficient, dependable turning solutions.
