DNMG 150408 T515 Turning Insert — Tungaloy

The DNMG150408 T515 is an ISO-standard rhombic turning insert designed for economical external and internal turning of cast iron with a focus on stable chip control and reproducible results.

• ISO rhombic insert, 55° cutting angle
• CVD-coated carbide grade T515
• Double-sided chipbreaker for cast iron
• Cylindrical hole for secure clamping

Consistent results for cast iron production

The rhombic geometry with a 55° cutting angle provides a stable engagement in turning operations, which reduces vibration and improves dimensional repeatability. The CVD coating on the carbide substrate increases wear resistance and supports higher cutting speeds compared with uncoated grades, making this insert suitable for productive, cost-conscious machining of cast iron components. Engineers benefit from predictable tool life and a steady surface finish without frequent tool changes.

Geometry and clamping that improve process security

A cylindrical hole and standard ISO form ensure compatibility with a wide range of holders when form, clearance angle, tolerance class, fastening method, size and thickness match. The rhombic shape gives flexibility for both external and internal turning, while the 0.8 mm corner radius helps maintain edge strength under interrupted cuts. These design choices reduce the need for trial-and-error setup and support consistent cycle times on batch production.

Coating and grade engineered for economy

The T515 grade is a CVD-coated carbide developed for the economic machining of cast iron; the coating improves thermal and abrasive resistance which in turn extends the interval between indexings. A double-sided chipbreaker improves fragmentation of brittle chips typical of cast iron, lowering the risk of chip-related damage and facilitating automated material removal. The result is a measurable improvement in throughput and lower per-part tooling cost.

Practical handling and inventory benefits

With a plate thickness of 4.76 mm and ISO sizing, stock management is simplified and compatibility across toolholders is straightforward when the holder matches the plate dimensions and tolerance class. The insert is indexed to present fresh cutting edges quickly, minimising downtime during production. Clear labelling and a consistent grade designation support rapid selection for changing production demands.
