CNMM 190612 T9235 Tungaloy indexable turning insert — CVD‑coated carbide, 1.2 mm corner radius

The CNMM190612 T9235 is an ISO‑standard indexable insert for external and internal turning, optimised for interrupted cuts and unstable machining conditions

• CVD-coated carbide grade T9235
• Suited for Stahl, unstable and interrupted cuts
• Rhombic CNMM form, 80° included angle
• 1.2 mm corner radius and cylindrical hole

Consistent performance in interrupted turning

The CVD‑coated substrate with grade T9235 delivers reliable wear resistance and a predictable flank life, particularly when cutting Stahl at moderate speeds. The coating reduces adhesion and improves edge integrity, which translates into fewer tool changes and more productive machine time. This design is especially beneficial where cuts are frequently interrupted or where rigidity is limited, offering a measurable uplift in process stability without complex parameter changes.

Clear advantages for chip control and surface finish

Equipped with a one-sided chipbreaker, the insert promotes controlled chip formation and evacuation, reducing the risk of built-up edge and improving surface integrity. The combination of a 1.2 mm corner radius and the chipbreaker geometry allows for a balance between strength at the cutting edge and achievable surface finish, meaning a stable feed strategy can be used to maintain component tolerances while avoiding excessive cutting forces.

System compatibility that simplifies setup and repeatability

As an ISO‑standard rhombic insert with a 80° included angle and 0° clearance, the CNMM form is widely compatible with common external holders and boring bars. The 6.35 mm thickness and the presence of a cylindrical hole provide secure mounting and repeatable seating, which helps to reduce setup variance and downtime. Choosing an ISO‑specified insert streamlines inventory and makes tool changes straightforward across multiple machines.

Application guidance and expected benefits

Designed primarily for turning operations, the insert performs best when matched with the appropriate stable holder and cutting parameters tuned for Stahl machining. Selecting the T9235 grade is a pragmatic choice where tool life under interrupted cuts is a priority; the result is improved process reliability and lower per‑part tooling cost through extended service intervals. For users seeking predictable outcomes in mixed production runs, this insert offers robustness without compromising adaptability.

FAQ

What machining tasks is this insert best suited for?
The insert is intended for external and internal turning; the CNMM190612 geometry and T9235 grade are optimised for interrupted cuts and less stable machining of Stahl.

How does the T9235 grade affect tool life?
The T9235 CVD coating enhances wear resistance and edge robustness, which increases tool life in interrupted operations compared with uncoated grades.

Can the insert be used in standard CNMM holders?
Yes, the ISO‑standard CNMM190612 form, 6.35 mm thickness, and cylindrical hole provide compatibility with standard external holders and boring bars designed for CNMM inserts.

What chip control can be expected from the insert?
The one-sided chipbreaker promotes predictable chip formation and evacuation, improving surface finish and reducing the likelihood of built‑up edge during turning of Stahl.

Is the insert suitable for high‑speed turning?
The T9235 grade is formulated for robust performance at moderate cutting speeds and interrupted cuts; for sustained high‑speed applications, evaluation of cutting parameters is recommended.
