CNMG 120404 T9235 ISO turning insert (rhomboid, 0° clearance) – Tungaloy

The CNMG120404 T9235 is an ISO rhomboid turning insert designed for external and internal turning of steel, offering a tough carbide grade for interrupted cuts and unstable machining situations.

• CVD-coated carbide grade T9235
• Double-sided chipbreaker for interrupted cuts
• 0° clearance for secure seating
• Rhomboid form with cylindrical hole

Reliable chip control even in interrupted turning

The combination of a double-sided chipbreaker and a CVD-coated carbide substrate provides consistent chip formation under variable cutting conditions. The T9235 tough grade is formulated for steel at lower cutting speeds and for operations where the cut is interrupted or the setup lacks rigidity; this results in fewer tool failures and steadier cycle times. By stabilising chip flow, the insert helps to reduce rework and downtime, making production more predictable and cost-effective.

Secure seating and ISO compatibility for fast tool changes

The insert follows ISO standards and features a rhomboid form with a cylindrical hole, enabling straightforward mounting in matching holders. The 0° clearance ensures firm seating while the 80° geometry supports a broad range of turning tasks. Compatibility is determined by form, clearance, tolerance class, fastening method, size and thickness; matching these parameters with the selected holder minimises vibration and promotes repeatable accuracy in both external and internal turning operations.

Tough grade and coating for extended tool life

A CVD coating on a carbide substrate gives the insert the wear resistance required for abrasive steels and intermittent cuts. The T9235 grade emphasises toughness over extreme hardness, which pays off where chipping risk is elevated or where surface contact is inconsistent. This balance between toughness and coating performance elevates tool life and reduces the frequency of insert changes, contributing to lower tooling costs per component and fewer machine stops.

Practical application guidance and setup recommendations

The ISO CNMG form is versatile for general turning; select the chipbreaker and grade to match the workpiece material, cutting parameters and machine stability. For steel and interrupted cuts, the T9235 grade with its 0.4 mm corner radius is a reliable choice to maintain edge strength while achieving acceptable corner definition. Ensure the holder matches the ISO geometry and that clamping components are in good condition to exploit the insert’s mechanical advantages and achieve consistent surface finish and dimensional control.
