DNMA 150408 T515 — Tungaloy ISO turning insert for turning

DNMA150408 T515 is an ISO-standard rhombic indexable insert designed for economic machining of cast iron in external and internal turning applications.

• CVD-coated carbide grade T515
• Designed for cast iron machining
• Rhombic form with 55° lead angle
• 0.8 mm corner radius for precision

Reliable performance for cast-iron turning operations

The T515 grade is a CVD-coated carbide developed for cost-effective machining of cast iron. Its coating improves thermal and abrasive resistance, which extends tool life under continuous cutting conditions and reduces changeover frequency. The rhombic geometry and 55° lead angle deliver a favourable cutting action for both external and internal turning, while the 0.8 mm corner radius helps maintain dimensional accuracy on profiles and shoulders. For production environments where repeatability and predictable wear behaviour are essential, this insert provides a balanced combination of life and surface finish.

Compatibility and secure clamping for consistent results

Compatibility with a toolholder depends on form, clearance angle, tolerance class, fastening method, size and thickness. The indexable design includes a cylindrical locating hole and a plate thickness of 4.76 mm, enabling stable mounting in ISO-compatible holders and boring bars. The ISO-series construction simplifies inventory management across toolrooms because holders and clamping sets follow the same standard. Where interrupted cuts or unstable setups are expected, selecting a suitable holder and clamping kit improves stability and allows the coating and carbide substrate to perform as intended.

Practical benefits and application guidance

As an insert without a built-in chipbreaker, cutting conditions should be matched to the workpiece and process stability; choosing the correct chip-control geometry and cutting data will enhance evacuation and surface quality. The carbide substrate combined with the CVD layer offers good resistance to edge wear, making the insert suitable for medium to high cutting speeds where economical throughput matters. Typical uses include turning cast-iron components, finishing shafts and general-purpose operations where consistent life and process reliability are priorities. For specific parameter settings and recommendations for interrupted cuts or unstable workpieces, Metav Werkzeuge can supply tailored guidance.
