DNGA150408 LX21 Tungaloy turning insert — rhombic ISO insert for precision turning, 0.8 mm radius

The DNGA150408 LX21 Tungaloy turning insert is an ISO‑standard rhombic indexable plate designed for external and internal turning applications, offering a balanced combination of wear resistance and edge stability.

• ISO‑standard rhombic insert for turning
• LX21 grade for wear resistance and edge stability
• 0.8 mm nose radius for accurate profiling
• Cylindrical hole and 0° relief for secure clamping

Improved tool life through optimised grade and edge stability

The LX21 grade from Tungaloy provides a careful balance of wear resistance and toughness, which translates directly into longer tool life and more predictable performance in turning operations. By selecting a grade that emphasises stable cutting edges, machining interruptions are reduced and component quality remains consistent. The ISO configuration ensures repeatable geometry and makes tool replacement straightforward, contributing to lower downtimes and improved process reliability.

Precise geometry for consistent surface finish and form turning

A 0.8 mm nose radius combined with the rhombic geometry delivers reliable edge engagement for accurate profiling and small-radius contours. The insert’s 0° relief angle and cylindrical hole contribute to a stable clamping interface when paired with a compatible holder, so vibration is minimised and surface finish is improved. Because the system comprises the ISO insert, a matching external holder or boring bar, shims/clamp sets and spare screws, correct assembly preserves the intended cutting geometry and ensures reproducible results.

Practical selection guidance for reliable machining

For turning tasks, choose the appropriate chipbreaker and grade according to the workpiece material, cutting parameters and machine stability; the supplied insert is provided without a chipbreaker, so match the insert geometry to the machining goal. Compatibility with the clamping system depends on form, clearance angle, tolerance class, fastening, size and thickness, so verify these dimensions when replacing inserts in existing toolholders. Using a carbide substrate tailored for turning operations supports productive material removal while maintaining dimensional accuracy.
