CNGA120404 LX10 Tungaloy turning insert — ISO rhombic, 80° geometry

The CNGA120404 LX10 Tungaloy is an ISO rhombic indexable insert engineered for external and internal turning applications, offering a balanced combination of wear resistance and cutting-edge edge stability.

• ISO rhombic insert, 80° cutting angle
• LX10 Tungaloy grade for wear resistance
• 0.4 mm corner radius for precision turning

High productivity from the LX10 cutting grade

The LX10 grade is a Tungaloy-developed carbide composition optimised for a broad range of turning tasks. Its balance of wear resistance and toughness reduces flank wear and extends edge life under mixed cutting conditions, which supports longer uninterrupted cutting cycles. For production environments where consistent tool life matters, the carbide grade reduces downtime for index changes and contributes to predictable cycle times. Selecting this grade can lower tooling consumption while maintaining dimensional consistency on batch runs.

Geometry that supports accurate diameters and surface finish

A rhombic plate with an 80° approach angle and a 0.4 mm corner radius provides a versatile compromise between strength and finishing capability. The combination of 12 mm nominal size and a plate thickness of 4.76 mm ensures stable clamping and reduced vibration when mounted correctly, improving surface integrity and repeatability. The insert’s cylindrical central hole secures positive location in the clamping assembly; this, together with the ISO form, simplifies replacement and maintains consistent seat contact for accurate re‑indexing.

Designed for controlled chip formation and stable cutting

This insert is supplied without a chipbreaker, which makes it suitable for applications where a neutral cutting geometry is preferred or where the holder provides chip control. The LX10 composition complements the geometry to deliver stable cutting-edge behaviour, especially in steady cutting conditions. For variable materials or interrupted cuts, pairing the plate with an appropriate holder and optimised cutting data will enhance process stability. The specification supports both roughing with conservative parameters and finishing passes where small radii improve surface quality.

Simple integration into ISO turning systems

As part of an ISO turning plate system, the insert fits into a standard assembly comprising the indexable plate, a matching external holder or boring bar, a shim/clamping set and spare screws. Compatibility is determined by insert form, clearance angle, tolerance class, fastening method, nominal size and thickness; therefore, attention to these parameters ensures correct seating and torque transmission. The standardised designation and the Tungaloy grade facilitate straightforward tool-room management and predictable reordering via Metav Werkzeuge.
