TNMA160408 T515 turning insert — triangular ISO turning insert by Tungaloy

A TNMA160408 T515 insert designed for ISO‑standard external and internal turning, optimised for efficient machining of cast iron components.

• CVD‑coated carbide grade T515
• Economical for cast iron machining
• Triangular 60° insert, 0.8 mm radius
• 16 mm ISO size, 4.76 mm thickness

Proven economy and consistent tool life for cast iron turning

The CVD‑coated carbide composition and T515 grade provide a robust cutting edge that balances wear resistance with cost‑effectiveness. For production environments where cycle time and tool longevity matter, this insert delivers a stable performance profile across interrupted and continuous cuts. The coating reduces adhesive wear and improves resistance to thermal and mechanical stress, which helps maintain component tolerances and reduces the frequency of index changes. Compatibility with ISO holders is defined by form, clearance angle, tolerance class, mounting method, size and thickness, so the insert integrates into established tool systems without redesign.

Exact geometry for repeatable results and simple holder matching

The triangular 60° geometry and 0.8 mm corner radius give a reliable cutting corner for shoulder work and general turning, while the 4.76 mm thickness and 16 mm ISO size ensure mechanical stability under moderate cutting forces. The insert’s central cylindrical hole supports positive clamping and accurate seating in standard clamping sets. Because the holder fit depends on multiple dimensions, the system approach—insert, matching outer holder or boring bar, backing plate/clamp set and replacement screws—ensures a repeatable set‑up and minimises setup time. This configuration simplifies production planning and reduces scrap caused by misalignment.

Application guidance and practical benefits for workshop use

Intended primarily for turning and optimised for cast iron machining, the grade selection supports variable cutting speeds and interrupted cuts typical in serial production or repair work. The absence of an integrated chipbreaker makes the insert suitable where chip control is managed by cutting parameters, coolant strategy or external chip guiding, offering flexibility for differing process demands. For teams less familiar with insert selection: the ISO‑standard designation and the clear specification of geometry and coating help in choosing the correct counterpart holder and cutting data, enabling faster commissioning and fewer trial cuts.
