CNGA120408 LX11 indexable turning insert — 80° rhombic, cemented carbide (Tungaloy)

The CNGA120408 LX11 is an ISO-standard indexable insert designed for external and internal turning; compatible holders are determined by form, clearance angle, tolerance class, fixation, size and thickness.

• ISO-standard rhombic geometry, 80° cutting angle
• Tungaloy LX11 grade for wear resistance and toughness
• Cemented carbide substrate for reliable edge life
• Cylindrical hole and 4.76 mm plate thickness

Stable, predictable performance for demanding turning

The ISO-compliant rhombic geometry delivers repeatable clamping and predictability across different toolholders, which reduces setup variance on the shop floor. The cemented carbide substrate combined with the LX11 grade balances wear resistance and toughness; this means fewer indexings and a consistent surface finish during batch production. For shops running mixed workpiece types, a standardised insert form simplifies inventory and replacement procedures while maintaining cutting stability.

Faster integration and less machine downtime

Compatibility is determined by insert form, clearance angle, tolerance class, fixation method, size and thickness; choosing an insert that matches these parameters avoids time-consuming rework of holders. The system comprises the insert, a matching external holder or boring bar, a shim or clamping set and spare screws, enabling quick replacements and consistent seating. As a result, machine uptime is improved and tool changeover becomes a routine, low-risk operation rather than a production bottleneck.

Consistent edge stability and adaptable chip behaviour

The LX11 grade from Tungaloy is engineered to provide a measured combination of edge stability and resistance to abrasive wear. That balance supports longer component runs with fewer interruptions. The insert is supplied without a chipbreaker, allowing the selection of an appropriate chipcontrol geometry or cutting parameters to match the workpiece material and system rigidity. The result is optimised chip formation, improved surface quality and reduced risk of built-up edge when machining under varying conditions.

Practical shop-floor specifications that enhance rigidity

Key dimensions influence real-world performance: the 80° rhombic cutting angle provides mechanical strength at the cutting edge; the 0° rake (clearance) yields a neutral cutting action suitable for a wide range of turning tasks; the 0.8 mm corner radius governs allowable depth of cut and influences finish; the 4.76 mm plate thickness contributes to stiffness and vibration resistance; the cylindrical mounting hole ensures secure clamping in standard holders. Together these specifications make the insert a reliable choice for systematic turning operations where predictable results are required.

FAQ

What turning tasks is this insert suited to?
The CNGA120408 LX11 insert is intended for both external and internal turning; its ISO rhombic shape and balanced LX11 grade make it suitable for general turning operations where predictable edge life is required.

How does the LX11 grade affect performance?
The LX11 grade from Tungaloy combines wear resistance and toughness to deliver stable edge performance and prolonged tool life under typical turning conditions.

Is a specific holder required for this insert?
Compatibility depends on holder form, clearance angle, tolerance class, fixation, size and thickness; using a matching ISO‑compliant holder ensures correct seating and clamping of the CNGA120408 insert.

Can this insert control chips without a chipbreaker?
The insert is supplied without a chipbreaker; chip control is achieved by selecting the correct cutting geometry or adapting cutting parameters and the holder setup to the workpiece material and system rigidity.
