CNGN120712 LX10 indexable turning insert for turning by Tungaloy

CNGN120712 LX10 Tungaloy indexable insert designed for ISO-standard turning applications, featuring an 80° rhombic form and a 1.2 mm corner radius for stable workholding and consistent surface results

• ISO CNGN format, 80° rhombic geometry
• LX10 grade for wear resistance and toughness
• Carbide substrate for high productivity
• 1.2 mm corner radius for smooth profiling

Reliable geometry for consistent turning accuracy

The ISO-design of this insert ensures predictable seating and repeatability in standard holders. The 80° rhombic shape provides a balanced cutting face suitable for both external and internal operations, while the 1.2 mm corner radius helps smooth tool engagement and reduces chatter on less rigid setups. Because the insert conforms to ISO dimensions, changeovers are straightforward and setup time is reduced, supporting uninterrupted production and consistent part quality. The neutral relief and standard form make the component straightforward to integrate into established tool systems.

Grade and substrate engineered for longer runtimes

The LX10 Tungaloy grade complements the insert geometry by balancing wear resistance and toughness, resulting in a cutting edge that retains form under intermittent loads and varying workpiece conditions. Manufactured on a carbide substrate, the insert is intended to provide stable performance across a range of turning tasks; the combination of grade and substrate reduces flank wear and supports repeatable surface finish. For operations where a compromise between edge life and impact resistance is required, this grade is designed to reduce unscheduled tool changes and maintain productivity.

System compatibility and operational considerations

Integration into a tool system requires attention to holder form, clearance, tolerance class, attachment and thickness; the insert pairs with matching external holders or boring bars and uses the correct shim/clamping set and replacement screws for secure fixing. The insert’s 0° relief denotes a neutral relief geometry that interacts with holder rake and insertion angle; toolmakers should verify holder geometry to achieve the desired cutting engagement. Supplied without a chipbreaker, the plate allows selection of chip control strategies tailored to the workpiece and machining stability—choose an appropriate chip control or adjust cutting parameters where required.

Productivity benefits and typical applications

Designed for ISO-conform turning tasks, the indexable plate supports efficient machining of turned parts with predictable maintenance intervals. Stable edge properties reduce rework and increase machine uptime, while the standardised format simplifies inventory and tool planning across multiple machines. Typical use cases include general external and internal turning where a robust corner radius and balanced grade improve surface finish and dimensional consistency. The construction aims to deliver reliable performance in production environments where changeover speed and repeatability are decisive advantages.

FAQ

Is this insert suitable for both external and internal turning?
Yes. The CNGN120712 LX10 Tungaloy insert is designed for ISO-conform external and internal turning applications; selection of holder and cutting parameters determines final performance.

What benefits does the LX10 grade provide?
The LX10 grade on this Tungaloy indexable plate combines wear resistance with edge stability, extending useful cutting life while maintaining consistent surface quality.

How is the insert secured in the holder?
The insert is mounted in a compatible ISO holder or boring bar, using the appropriate shim or clamping kit and replacement screws specified for the holder and the insert size.

What does the 0° relief angle mean in practice?
A 0° relief indicates a neutral relief geometry on the insert itself; final cutting clearance depends on holder geometry and seating, so verification of holder-insert combination is recommended.

Does the insert include a chipbreaker?
No, the insert is supplied without a chipbreaker, allowing chip control to be selected according to workpiece material and machining conditions
