CNMG 120408 T9235 Turning insert (rhombic, 80°) – Tungaloy

CNMG 120408 T9235 is an ISO-standard indexable turning insert designed for external and internal turning, optimised for steel machining under unstable conditions

• ISO 120408 compatibility
• CVD-coated carbide grade T9235
• Double-sided chipbreaker design
• 0.8 mm nose radius, 80° rhombic

Consistent performance for interrupted and unstable turning

The CVD-coated carbide grade T9235 delivers a balance between toughness and wear resistance, making it particularly suitable for steel where lower cutting speeds or interrupted cuts occur. The substrate and coating combination promotes stable chip formation, which reduces built-up edge and helps maintain cutting force stability in less rigid set-ups. This robustness translates into fewer rejects and more predictable cycle times, supporting continuous production runs with fewer unscheduled tool changes.

Geometry and dimensions that simplify set-up and repeatability

The 80° rhombic geometry with a 0.8 mm nose radius provides a predictable contact area and excellent edge strength for semi-roughing and finishing passes. The insert’s ISO code 120408 indicates the standardised form and size, so compatibility with matching holders is determined by form, clearance angle, tolerance class, fastening, size and thickness. The 0° clearance angle and the cylindrical hole facilitate secure clamping and repeatable positioning, while the 4.76 mm plate thickness supports rigidity in typical turning applications.

Productivity advantages and practical benefits in the workshop

Using a grade optimised for tougher conditions reduces downtime caused by edge failures and frequent indexings. The double-sided chipbreaker allows two cutting edges per side, extending time between replacements and improving cost-efficiency. For workshops handling mixed batches or variable setups, the combination of indexable insert design and standard ISO sizing simplifies inventory and shortens changeover times. Selecting the appropriate chipbreaker and grade according to material and stability ensures optimal surface finish and longer tool life.

System integration and handling recommendations

The insert is intended for use as part of a complete turning system comprising an ISO turning insert, a compatible external holder or boring bar, a shim/pack and replacement screws. Compatibility hinges on matching the insert form and dimensions to the clamping system; verify tolerance class and fastening style when ordering. For best results, pair the T9235 grade with a holder that provides sufficient rigidity and use cutting parameters suited to lower speeds when machining steel in unstable conditions.
