DNMA 150408 T5115 Tungaloy turning insert — rhombic 55° geometry, 0.8 mm radius

The DNMA150408 T5115 is an indexable turning insert designed for external and internal turning, optimised for cast iron applications with ISO‑standard form and reliable clamping compatibility

• ISO rhombic insert, 55° cutting geometry
• CVD-coated carbide grade T5115
• 0.8 mm corner radius for stable cuts
• Suitable for external and internal turning

Consistent geometry for predictable machining results

The insert combines ISO conformity and a rhombic 55° cutting geometry to ensure reproducible locating and clamping in standard holders. The indexable insert format with a 0.8 mm corner radius and 4.76 mm plate thickness provides a compromise between edge strength and accessibility for general turning tasks. Compatibility with the toolholder is defined by form, relief angle, tolerance class, fastening method, size and thickness; this guarantees repeatable seating and reduces vibration-induced wear. The cylindrical hole and the standardised shape support secure fixing and fast index changes, which contributes to lower setup times and a steady production flow.

Reliable performance on cast iron with CVD-coated carbide

The T5115 grade is a CVD-coated carbide designed as a universal solution for cast iron, offering a balanced combination of wear resistance and edge stability. In practice this means longer effective cutting life under typical chip‑forming conditions and a stable cutting edge when encountering interrupted cuts or variable material batches. Stable chip formation and controlled wear behaviour help to maintain surface finish and dimensional consistency, which supports higher first‑pass yields and reduces the need for rework. Where a chipbreaker is required, selection should follow the workpiece material, turning strategy and machine stability.

Practical system guidance for workshop integration

The insert forms part of a system: an ISO turning insert, a matching external holder or boring bar, a shim/clamping set and replacement screws. Since the plate is supplied without a chipbreaker, choose an appropriate breaker and holder that match workpiece material and the intended machining parameters. For internal turning or restricted access, the rhombic 55° geometry often improves reach while maintaining a robust cutting edge. Routine checks of clamp torque and seat cleanliness will ensure the holder and insert maintain consistent contact and repeatable machining results. For complex applications or mixed‑material batches, consider discussing holder options and cutting data with a technical consultant to optimise process reliability.
