DNMG150408 T9235 turning indexable insert (55° rhombic, Tungaloy)

The DNMG150408 T9235 is an ISO-form turning indexable insert engineered for external and internal turning, offering a tough CVD-coated carbide grade for interrupted cuts and unstable set-ups

• CVD-coated carbide grade T9235
• Rhombic geometry with 55° cutting angle
• Double-sided chipbreaker for interrupted cuts
• 0.8 mm corner radius for robust engagement

Consistent performance in unstable turning conditions

The combination of a CVD-coated surface and the T9235 tough grade provides a reliable balance between wear resistance and fracture toughness, making this insert well suited to steel machining at reduced cutting speeds. The substrate material is carbide, which sustains edge integrity during heavy interruptions and variable chip loads; this results in fewer edge failures and more predictable tool life. For operations where stability is limited, the chosen grade reduces the risk of catastrophic wear, enabling steadier cycle times and more consistent component quality.

Clear ISO compatibility and secure clamping

Manufactured to ISO dimensions, the insert features a rhombic 55° geometry and a cylindrical hole for positive location in compatible holders. Compatibility with a specific holder is determined by the insert form, relief angle, tolerance class, fastening method, size and thickness; the relief angle is 0°, thickness is 4.76 mm and the insert size corresponds to 15 mm. These standardised attributes simplify selection and replacement in ISO systems, allowing straightforward matching with established turning holders and clamping kits. Correct matching reduces setup time and ensures repeatable cutting positions.

Design elements that reduce downtime and protect the edge

A double-sided chipbreaker on this insert provides reliable chip control for interrupted and varying cuts while offering two usable cutting edges per side where applicable, contributing to economical edge utilisation. The 0.8 mm corner radius delivers a stable engagement at the cutting edge, improving resistance to chipping during entry and exit phases. Together, these features support longer in-process intervals and fewer unscheduled tool changes, which is particularly beneficial for small-batch production and workshop environments with mixed stability.

Application guidance and pragmatic selection

The insert is optimised for external and internal turning of steel; selection of the exact chipbreaker and the matching grade should be aligned with workpiece material, machining strategy and machine-tool rigidity. In practice, choose lower cutting speeds with this tough grade when encountering interrupted cuts or unstable clamping to exploit the fracture resistance of the substrate. The full machining system includes the ISO insert, an appropriate external holder or boring bar, a backing plate/clamping set and replacement screws — ensuring secure fixation and repeatable results. Technical matching for specific workpieces and recommended cutting data can be provided by Metav Werkzeuge’s consultants for process planning and optimisation.

FAQ

What materials is this insert recommended for?
The DNMG150408 T9235 insert is recommended primarily for machining steel; the T9235 grade is a tough, CVD-coated carbide designed for lower cutting speeds and interrupted cuts in steel.

How does the 0.8 mm corner radius affect cutting performance?
A 0.8 mm corner radius on the DNMG150408 increases edge strength for robust engagement, reducing the likelihood of chipping during entry and exit and extending in-process tool life.

Is the insert compatible with standard ISO toolholders?
Yes, the DNMG150408 conforms to ISO dimensions; compatibility depends on holder form, tolerance class, fastening and thickness, and the insert uses a cylindrical hole for location.

What advantage does the double-sided chipbreaker provide?
The double-sided chipbreaker on this insert improves chip control during interrupted cuts and can extend the usable life per insert by offering additional usable edges, enhancing productivity.

Which features help when machining under unstable conditions?
The combination of CVD-coated carbide, the tough T9235 grade and the 0.8 mm corner radius makes this insert suited to unstable setups by improving fracture resistance and preserving cutting-edge integrity.
