CNMG 120408 T9235 turning insert by Tungaloy — rhombic, 0.8 mm nose radius

A CNMG 120408 T9235 indexable turning insert designed for external and internal turning where a tough, CVD-coated carbide grade is required for unstable conditions and interrupted cuts.

• CVD-coated carbide T9235 for tough steel conditions
• Rhombic CNMG 12 × 4.76 mm plate geometry
• 0.8 mm nose radius for medium finishing
• Double-sided insert with cylindrical hole

Reliable cutting in interrupted and unstable conditions

The insert is built from CVD-coated carbide, a combination that delivers high resistance to abrasive wear while preserving edge strength. The T9235 tough grade is engineered specifically for machining steel at lower cutting speeds and under interrupted or unstable cutting regimes; this reduces the risk of premature edge chipping and supports longer tool life. By using a tougher substrate and a wear-resistant coating, energy from impact and thermal fluctuations is dissipated more reliably, resulting in consistent part quality and fewer insert changes during batch work.

Precise compatibility and predictable insert seating

Designed to the ISO series of indexable turning plates, the rhombic geometry and the specified dimensions ensure repeatable seating in matching holders. The plate thickness of 4.76 mm, the cylindrical hole and the standard tolerance make the indexable insert compatible with a wide range of CNMG-capable toolholders; compatibility is governed by form, relief angle and tolerance class. The 0° relief angle and the 80° included angle provide a stable cutting edge orientation that is suited to general turning tasks, and the double-sided design offers economical use through indexability and reduced changeover frequency.

Productivity, surface finish and workshop efficiency

With a 0.8 mm nose radius, the insert achieves a balance between surface finish and strength at the cutting edge, suitable for medium finishing passes without sacrificing robustness. The double-sided nature and ISO-format standardisation support fast tool changes and predictable cost per part. For operations requiring less operator intervention and faster throughput, this insert reduces downtime and improves process stability. If machining parameters need optimisation for a specific alloy or setup, Metav Werkzeuge can provide application advice to match feed and speed to the grade and geometry chosen.

FAQ

What materials is this insert suitable for?
The CNMG 120408 T9235 insert is optimised for steel machining; the T9235 grade is designed for tougher conditions and interrupted cuts.

Can this insert be used in any CNMG holder?
Compatibility is determined by the holder form, relief angle, tolerance and plate thickness; the insert follows ISO CNMG standards so it fits CNMG-capable holders that match these parameters.

How does the T9235 grade affect cutting parameters?
The T9235 tough carbide grade favours lower cutting speeds and provides improved resistance to impact, making it suitable where interrupted cuts or unstable setups occur.

Is the insert indexable and economical for batch production?
Yes, the double-sided CNMG geometry allows indexing of the insert, reducing tooling cost per edge and minimising changeover time.
