Take advantage of the combination of a CVD-coated carbide grade engineered for tough steel applications, a 55° rhombic geometry for reliable engagement, and a 1.6 mm corner radius for robust edge life — available directly via Metav Werkzeuge or through consultation with our advisors.

DNMG150616 T9235 turning insert — DNMG series, Tungaloy

The DNMG150616 T9235 is a CVD-coated carbide turning insert designed for external and internal turning where interrupted cuts and less-stable setups demand a tough grade and predictable performance.

• CVD-coated carbide grade T9235
• 55° rhombic geometry
• 1.6 mm corner radius
• Double-sided chipbreaker design

Maximise productivity in unstable cutting conditions

The combination of a CVD coating and a tough carbide grade (T9235) delivers improved resistance to edge chipping during interrupted cuts and unstable setups. This specification is aimed at turning operations where reduced cutting speeds are preferable to protect the tool edge; the result is longer in-process life and fewer unexpected tool changes. Process planners will value the insert’s capacity to maintain dimensional consistency under fluctuating conditions, which supports higher overall machine uptime and repeatable part quality.

Stable engagement and secure clamping for repeatable accuracy

The 55° rhombic geometry and 6.35 mm plate thickness offer mechanical stability during both external and internal turning, while the central cylindrical hole enables reliable clamping in standard ISO-compatible holders. Compatibility with a holder is determined by form, relief angle, tolerance class, fixing method, size and thickness; adherence to these ISO parameters ensures secure seating and consistent cutting orientation. Clear specification of geometry and mounting details simplifies tool selection and reduces setup time on the shop floor.

Optimised edge form for steel machining and fewer process interruptions

A 1.6 mm corner radius combined with a double-sided chipbreaker supports robust chip control and a balanced cutting edge that copes well with the mechanical shocks of interrupted machining. The grade’s toughness makes it suitable for steel applications at lower cutting speeds, where the priority is avoiding premature edge wear or fracture rather than maximising surface speed. For production environments with mixed batch sizes or unstable fixtures, this insert provides a pragmatic balance between durability and versatility.

Practical fit into ISO-based tool systems

As part of an ISO insert system, the plate integrates into an assembly consisting of a compatible external holder or boring bar, a support pad or clamp set and replacement screws. The ISO designation and standardised dimensions simplify inventory management and facilitate interchangeability across machines that accept DNMG geometry. Specification-driven selection — matching the chipbreaker and grade to the workpiece material and machining conditions — yields measurable gains in cycle stability and cost-efficiency.

FAQ

Is this insert suitable for interrupted turning in steel?
The DNMG150616 T9235 insert from Tungaloy is designed as a tough, CVD-coated carbide grade specifically for steel machining in interrupted and unstable cutting conditions.

What holder characteristics are required for correct fitment?
Correct fitment requires a holder matching the ISO DNMG form with compatible relief angle, tolerance class, fixing method, size and plate thickness as specified for the insert.

How many usable cutting edges does the plate offer?
With a double-sided design and rhombic geometry, the insert provides reversible cutting edges; the exact number of successive edges depends on the chosen index strategy and machining parameters.

Which machining tasks benefit most from this grade and chipbreaker?
Operations involving intermittent cuts, roughing of steel with variable stability, and setups where edge robustness outweighs maximum cutting speed will gain the most from the T9235 grade and its double-sided chipbreaker.

Can this insert be used for internal turning as well as external turning?
Yes, the geometry and standard ISO dimensions make the insert suitable for both external and internal turning when paired with the appropriate holder or boring bar.
