Combining a CVD-coated carbide grade with an 80° rhombic geometry and a 1.6 mm corner radius, this insert is optimised for stable performance in steel turning, especially under interrupted or unstable cutting conditions. Take advantage of its double-sided design and ISO compatibility for predictable indexability; order the CNMG120416 directly via Metav Werkzeuge or consult the specialists for holder matching and application advice.

CNMG120416 T9235 Tungaloy indexable turning insert — 80° rhombic, double-sided chipbreaker

The CNMG120416 T9235 is an ISO-standard indexable turning insert intended for external and internal turning of steel, providing a tough grade for lower cutting speeds and heavily interrupted cuts.

• CVD-coated carbide grade T9235
• Designed for steel with interrupted cuts
• Rhombic 80° geometry, 1.6 mm corner
• Double-sided insert with cylindrical hole

Consistent cutting life in unstable conditions

The combination of a CVD-coated surface and a tough carbide substrate delivers predictable wear behaviour when machining steel under variable conditions. The T9235 grade is formulated to resist chipping and maintain edge stability at lower cutting speeds, making it suitable for applications where intermittent engagement or part vibration occurs. As a result, users can expect fewer unplanned tool changes and a more consistent component quality, which supports efficient production planning and reduced downtime.

ISO compatibility and secure clamping for reliable indexing

ISO standardisation simplifies the choice of a matching turning holder, but compatibility still depends on geometry and mounting details. The insert’s rhombic 80° form, 0° clearance angle and defined thickness mean that correct selection of an external or internal holder, a corresponding shim or clamp, and replacement screws is essential. When mounted correctly, the double-sided design enables quick index changes and reproducible seating, which reduces set-up time and ensures repeatable tool offsets in serial machining.

Practical guidance for application and chip control

This insert features a double-sided doppelseitig chipbreaker design (available on both faces) and a cylindrical hole for positive locating; these elements support stable chip formation and evacuation in turning tasks. The geometry and the 1.6 mm corner radius favour medium to heavy cuts where edge robustness is required. Select the chipbreaker and cutting parameters in line with workpiece rigidity and machine capability: the tougher T9235 grade is particularly effective in less rigid setups or when cuts are frequently interrupted, helping to extend the interval between index changes and lower tooling cost per component.

FAQ

Which materials is this insert intended for?
The T9235 grade is specified for machining steel; CNMG120416 T9235 is optimised for lower cutting speeds and applications with interrupted engagement in steel components.

Is the insert reversible and how many cutting edges are available?
This CNMG120416 insert is double-sided, providing two usable edges per face where applicable; the design supports economical indexing and reuse of the cutting edges.

What geometry and corner radius does the insert offer?
The insert uses a rhombic 80° geometry with a 1.6 mm corner radius, offering a balance of edge strength and versatility for a range of turning operations.

How is chip control handled with this insert?
A double-sided chipbreaker is integrated to promote stable chip formation in turning; chipbreaker selection should match the workpiece stability and cutting conditions for optimal results.

Can the insert be used for internal turning as well as external work?
Yes — ISO-standard configuration and the rhombic form make CNMG120416 suitable for both external and internal turning operations, provided the correct holder and clamping are used.
