CNMG 120408 T9235 CNMG turning insert by Tungaloy — CVD-coated carbide, rhombic 80°

CNMG 120408 T9235 is an ISO-format turning insert for general external and internal turning tasks, engineered to deliver reliable performance under unstable conditions and interrupted cuts.

• CVD-coated carbide T9235
• Rhombic plate, 80° lead angle
• Double-sided chipbreaker, with hole
• 4.76 mm plate thickness

Consistent metal removal through a robust grade and geometry

The T9235 grade combines a CVD-coated surface with a carbide substrate to offer a tough cutting edge suited to machining Stahl under lower cutting speeds and variable conditions. The rhombic plate form with an 80° lead angle gives a favourable balance between cutting-edge strength and accessibility in external and internal profiles. This geometry supports reliable chip control and reduces the risk of unexpected breakage during interrupted cuts, which in turn helps to maintain process stability and predictable machining cycles.

Clear selection criteria and holder compatibility for efficient setup

Compatibility with a clamping system depends on form, relief angle (0°), tolerance class, fastening method, size and thickness (4.76 mm). The ISO designation and dimensional data simplify matching to existing ISO holders and boring bars; selecting a holder with the correct seat and clamping arrangement reduces set-up time and vibration. By choosing the proper chipbreaker and the T9235 sort for tougher conditions, set-up reliability increases and rework is less likely — a practical benefit for batch production and mixed runs.

Practical advantages: wear resistance and process security

The CVD layer enhances surface hardness and gives improved resistance to built-up edge formation when turning Stahl, while the tough substrate under the coating sustains impact loads. This results in longer effective tool life under unstable feeds and interrupted cuts and contributes to consistent surface finish. The double-sided chipbreaker design also provides two usable cutting edges per index, allowing economical utilisation of the insert and straightforward rotation when renewal is required.

Guidance for application and support

When machining with this insert class, consider lower cutting speeds and conservative feeds during initial trials to find the most productive balance for the workpiece material and machine rigidity. The system approach — matching insert, holder and clamping set — pays off in repeatable results.
