DNMA 150412 T5105 Wendeplatten - Tungaloy

Benefit from the combination of CVD‑coated carbide (T5105), a 55° rhombic geometry with 1.2 mm corner radius, and secure cylindrical‑hole clamping to achieve stable, high‑speed turning of cast iron; order via Metav Werkzeuge or consult our specialists for application guidance.

DNMA150412 T5105 DNMA 150412 T5105 ISO turning insert for turning – Tungaloy

DNMA150412 T5105 is an ISO rhombic turning insert designed for external and internal turning, optimised for high‑speed machining of cast iron under stable cutting conditions.

• CVD‑coated carbide grade T5105
• 55° rhombic geometry, 1.2 mm corner radius
• Cylindrical‑hole mounting for secure clamping
• ISO compatibility for standard toolholders

Consistent chip control and high‑speed performance

The CVD‑coated carbide composition of this insert delivers robust wear resistance in continuous high‑speed operations on cast iron, reducing flank wear and preserving cutting edge life. The T5105 grade is engineered for productive material removal where stability is maintained; the coating supports thermal and abrasive resistance so that machining windows remain wider and downtime for tool changes is reduced. For shops aiming to increase throughput, the combination of substrate and coating offers a predictable performance curve and longer effective cutting time.

Secure mounting and repeatable accuracy for reliable production

A cylindrical hole and standardised ISO geometry ensure fast, repeatable seating in compatible external holders or boring bars. The insert’s 55° lead angle and 0° clearance are matched to typical ISO‑form holders so that clamping forces are transferred reliably, improving positional repeatability and surface finish consistency. Dimensional data such as 15 mm insert size and 4.76 mm thickness facilitate correct holder selection and minimise setup time, enabling quicker index changes and consistent part tolerances across batches.

Lower operating costs through longer tool life and simple selection

Choosing an insert without an integrated chipbreaker simplifies selection when stability and workpiece rigidity are already ensured by the setup; this insert suits applications where a separate chip control strategy is applied. The combination of stable chip formation, longer tool life, and straightforward ISO compatibility reduces process variability and total cost per part. Paired with an appropriate holder and cutting parameters, the insert supports efficient machining cycles and predictable maintenance intervals, contributing to a more economical production flow.

FAQ

Is this insert suitable for cast iron machining?
Yes. The DNMA150412 T5105 insert uses a CVD‑coated carbide grade designed specifically for high‑speed machining of cast iron under stable conditions.

Can the insert be used for internal turning as well as external turning?
Yes. The ISO rhombic geometry and cylindrical‑hole mounting make this insert suitable for both external and internal turning applications when matched with the correct holder.

What is the corner radius and how does it affect surface finish?
The corner radius is 1.2 mm; a larger radius increases edge strength and can improve surface finish under stable cutting conditions, but it may require adjustments to feed and depth of cut.

Does the insert include a chipbreaker?
No. This insert is supplied without a chipbreaker, allowing the user to select chip control strategies suited to the workpiece, holder rigidity and machining parameters.

Which identifiers help when reordering this insert?
Reorder using the product designation DNMA150412 T5105, manufacturer article number 6850211, or SKU 6850211‑Tungaloy to ensure the correct ISO turning insert is supplied.
