CNGN 120712 LX11 — Turning insert, ISO-standard rhombic, 80° geometry (Tungaloy)

The CNGN 120712 LX11 is an ISO-standard rhombic indexable insert intended for general turning applications, offering robust edge life and predictable behaviour in production-oriented machining.

• ISO-standard rhombic insert 80° geometry
• LX11 grade with wear-resistant carbide
• 1.2 mm corner radius for stable cutting
• Compatible with ISO turning holders

Longer tool life through optimised grade and substrate

The LX11 designation denotes a Tungaloy-developed carbide grade that balances wear resistance and toughness for sustained cutting performance. Manufactured from cemented carbide, this insert minimises flank and crater wear in many turning scenarios, which reduces changeover frequency and supports longer production runs. As an indexable insert, it provides a cost-effective way to restore cutting edges without full-tool replacement, improving uptime and lowering per-part tooling cost.

Seamless integration with ISO tooling for secure setups

Designed to the ISO form and size conventions, the insert's 80° rhombic geometry and dimensional data (nominal 12 mm size and 7.94 mm thickness) ensure compatibility with standard turning holders. The 0° clearance specification and the insert’s tolerance class determine fit and repeatability; mounting is influenced by form, clearance angle, fastening method, size and thickness. This engineered compatibility simplifies tool selection and reduces setup time when matching inserts to holders and boring bars.

Stable cutting and consistent surface quality

A 1.2 mm radius at the corner offers a compromise between edge strength and surface finish, giving stable cutting forces and improved resistance to chipping. The lack of an integrated chipbreaker makes the insert suitable for applications where chip control is managed by tool path or coolant strategy rather than the insert geometry. With predictable edge behaviour, the component surface integrity benefits from fewer edge-related irregularities, leading to more consistent part quality and lower rework rates.

FAQ

What is the primary application of this insert?
The CNGN 120712 LX11 insert is designed for general turning operations, providing an ISO-standard solution for both external and internal turning tasks.

Which toolholders are compatible with this insert?
Compatibility depends on the holder’s form, clearance angle, tolerance class, fastening method, size and thickness; the CNGN120712 matches standard ISO turning holders built for 12 mm rhombic inserts.

What benefits does the LX11 grade deliver?
The LX11 grade from Tungaloy combines wear resistance and toughness to deliver stable edge life, reducing index changes and supporting consistent machining performance.

Does the insert include a chipbreaker or mounting hole?
This insert is supplied without a chipbreaker and without a hole, so chip control and clamping must be considered in the tool and process setup.
