CNMM 190612 T9235 CNMM indexable turning insert for turning – Tungaloy

CNMM190612 T9235 is a rhombic ISO indexable insert engineered for external and internal turning, offering a tough CVD-coated carbide grade suited to lower cutting speeds and unstable conditions.

• CVD-coated carbide T9235 grade
• ISO‑standard CNMM 190612 form
• 80° rhombic shape for versatile turning
• Corner radius 1.2 mm with cylindrical hole

Consistent chip control and durable cutting edge for interrupted cuts

The CVD-coated T9235 grade is formulated as a tough carbide mix that gives reliable performance when conditions are less stable or the cut is interrupted. This indexable insert offers a balanced hardness and toughness combination, which reduces the risk of chipping while preserving a useful edge life. For production environments where tool life and predictable wear are required, the coating improves abrasion resistance and helps maintain dimensional consistency over longer tool cycles.

Designed for ISO compatibility and straightforward mounting

Built to the ISO‑standard CNMM190612 geometry, the insert matches holders that accept the CNMM form and the specified tolerance class. The 80° rhombic plate shape and the cylindrical hole enable secure clamping in a wide range of external and internal turning holders. This compatibility simplifies logistics and inventory management: standardised mounting reduces setup time and helps ensure repeatable positioning across machines and fixtures.

Small corner radius for precise finishing and versatility

With a 1.2 mm corner radius, the insert balances strength and surface finish capability. The radius permits stable cutting forces for semi-finishing while still enabling acceptable surface quality on many steels. The single-sided chipbreaker geometry supports controlled chip formation; choosing the correct chipbreaker and grade according to workpiece material and rigidity will directly influence cycle stability and component tolerances.

Practical benefits for production planning and process reliability

Selecting this grade and geometry supports predictable machining under less-than-ideal rigidity or interrupted cuts, delivering a cost-effective compromise between tool life and cutting performance. The combination of CVD coating, robust carbide substrate and standardised ISO form enables efficient replacement and reproduci­­ble results across different lathes. For mixed-production shops machining a variety of steels, this insert reduces the need for frequent tool changes while maintaining process control.

FAQ

What materials is this insert suited for?
The CNMM190612 T9235 insert is designed primarily for machining steel under lower cutting speeds and offers robust performance when conditions are unstable or cuts are interrupted.

How does the T9235 grade differ from harder grades?
The T9235 grade emphasises toughness over maximum hardness, so the cutting insert resists chipping and performs better with interrupted cuts compared with harder, more brittle grades.

Can this insert be used for internal turning as well as external turning?
Yes, the ISO CNMM190612 geometry and the 80° rhombic form allow mounting in holders suitable for both external and internal turning operations.

What is the significance of the 1.2 mm corner radius?
A 1.2 mm corner radius provides a compromise between strength and surface finish, enabling stable cutting forces for semi-finishing while maintaining acceptable surface quality.

Is the insert supplied with a specific chipbreaker style?
The insert features a single-sided chipbreaker, optimised for controlled chip formation in the targeted steel applications described for this grade.
