CNMG160612 T9235 turning insert — CVD‑coated carbide, 80° rhombic | Tungaloy

The CNMG160612 T9235 is an ISO rhombic turning insert designed for external and internal turning of steel, offering a tough, CVD‑coated carbide grade for interrupted cuts and less stable machining conditions.

• CVD‑coated carbide grade T9235
• Rhombic 80° geometry for versatile turning
• Double‑sided chipbreaker for consistent chips
• 1.2 mm nose radius for balance of strength and finish

Consistent performance with a tough CVD coating

The combination of a CVD‑coating and a tough carbide substrate (grade T9235) delivers improved wear resistance and thermal stability compared with uncoated grades. In practice this means extended tool life and more predictable change intervals when machining steel at lower cutting speeds or with interrupted cuts. CVD coatings form a hard, thin layer that reduces flank wear and provides a thermal barrier; the result is a more stable process and fewer unplanned tool changes, which supports continuous production and cost efficiency.

Geometry engineered for stability and surface quality

The insert’s 80° included angle and rhombic shape make it suitable for a wide range of turning profiles, while the 1.2 mm nose radius balances cutting edge strength and surface finish. The double‑sided chipbreaker supplies repeatable chip control for many roughing and finishing passes, and the cylindrical hole allows secure screw clamping in compatible ISO toolholders. A 0° clearance specification increases edge strength where robustness is required rather than aggressive tool relief, so the component performs well in interrupted cuts and when machine stability is limited.

ISO compatibility and system considerations for predictable results

As an ISO‑standardised insert, compatibility with the toolholder depends on form, clearance angle, tolerance class, mounting method, size and thickness. The insert integrates into standard systems comprising an appropriate external holder or boring bar, a support/locking set and spare screws. Selecting the correct holder and clamping set is decisive for process reliability: a matching toolholder ensures correct seating, repeatable clamping and optimal heat dissipation, all of which contribute to more consistent surface quality and longer edge life.

Practical selection and application advice for turning steel

Choose the chipbreaker and grade to match the workpiece material, machining stability and type of cut; the T9235 grade is intended for steel applications at lower cutting speeds and for interrupted or unstable cutting situations. Properly paired with a suitable holder and clamping, the insert provides improved chip control and steadier cutting forces, reducing the risk of edge chipping and downtime. For specific machining strategies or to clarify holder compatibility, technical consultation is available to help define the best combination for a given component and machine setup.

FAQ

What materials is this insert suitable for?
The CNMG160612 T9235 insert is specified for machining steel and is particularly suited to interrupted cuts and less stable machining conditions thanks to its tough CVD‑coated carbide grade.

How does the 1.2 mm nose radius affect machining results?
A 1.2 mm nose radius provides a compromise between edge strength and surface finish; larger radii increase strength and allow heavier cuts, while smaller radii improve the ability to produce finer surface finishes.

Is the insert reversible or indexable?
The insert is double‑sided, offering two effective cutting edges per index position; this maximises usable edges before replacement and supports economical usage.

What should be considered for clamping and holder selection?
Compatibility depends on form, clearance angle, tolerance class, mounting method, size and thickness; correct seating and screw clamping in a suitable ISO toolholder are essential for repeatable performance.

Can this insert be used for internal turning (boring)?
Yes — the rhombic geometry and the CNMG form allow use in both external and internal turning operations, provided a compatible holder or boring bar is used and appropriate cutting parameters are selected.
