DNMG150412 T9235 turning insert — CVD-coated carbide, 55° (Tungaloy)

DNMG150412 T9235 is an ISO-format turning insert designed for external and internal turning of steel under interrupted or less stable cutting conditions.

• CVD-coated carbide grade T9235
• Optimised for unstable cutting conditions
• Double-sided chipbreaker for flexible use
• Rhombic form with cylindrical hole, 55°

Consistent cutting in unstable machining conditions

The CVD-coated carbide grade T9235 is formulated to deliver stable chip formation and durable edge life when machining steel at lower cutting speeds or where interruptions and varying rigidity occur. The coating provides thermal and adhesive resistance that reduces flank wear, while the substrate ensures toughness under shock loads. For production environments where insert life and predictable performance affect cycle times, this combination supports a more consistent output and fewer tool changes, improving overall process reliability.

Clear compatibility and simple mounting for faster set-up

The insert follows ISO dimensions and is supplied in a rhombic form with a cylindrical hole, enabling fast fitting in compatible indexable holders and boring bars. Compatibility is determined by form, clearance angle (0°), tolerance class, attachment method, size and thickness (4.76 mm); matching the insert to a holder that respects these parameters reduces runout and secures predictable cutting behaviour. The standardised geometry simplifies logistics and holder selection across mixed-machine fleets, reducing set-up time and potential errors in the workshop.

Effective chip control and edge geometry for everyday production

A double-sided chipbreaker combined with an edge radius of 1.2 mm offers a balance between robust edge strength and controlled chip flow, which is particularly valuable when facing interrupted cuts or variable feeds. The design supports both roughing passes and semi-finishing, enabling fewer insert changes and improved productivity. Describing technical choices: a larger edge radius improves edge strength and reduces microchipping, while the chipformer steers swarf away from the cutting zone to protect the component surface and tooling interface.

Practical handling and system approach for longer uptime

The ISO-series system setup envisages the insert together with a matched outer holder or boring bar, a shim/clamping set and replacement screws. Using ISO-format inserts allows standardised inventory management and facilitates faster tool changes. The insert’s 55° principal angle and robust substrate make it suitable for a wide range of turning operations; selecting the correct holder and clamping method preserves the insert’s life and achieves consistent surface quality. For maintenance planning, fewer interventions and predictable wear patterns translate directly into lower operating costs and higher machine availability.

FAQ

What materials is this insert optimised for?
The DNMG150412 T9235 insert is optimised for machining steel, particularly under interrupted or unstable cutting conditions where toughness and chip control are priorities.

Can the insert be used for internal turning as well as external turning?
Yes, the ISO-format geometry and rhombic profile make the insert suitable for both external and internal turning operations when paired with an appropriate holder or boring bar.

How does the T9235 grade improve performance in unstable conditions?
The T9235 carbide grade combines toughness and a wear-resistant CVD coating to withstand shock loads and reduce flank wear, providing longer tool life in interrupted cuts.

What should be considered when choosing a compatible holder?
Compatibility depends on the insert form, clearance angle (0°), tolerance class, attachment method, size and thickness (4.76 mm); selecting a holder that matches these parameters minimises runout and secures correct clamping.

Is the chip control suitable for finishing passes?
The double-sided chipbreaker and 1.2 mm edge radius offer controlled swarf evacuation and a stable cutting edge, making the insert effective for roughing and semi-finishing; final finishing may require a finer nose radius and specific geometry.
