CNGN 120708 LX11 ISO turning insert for precision external and internal turning — Tungaloy

CNGN120708 LX11 is a rhombic ISO turning insert designed for reliable external and internal turning in conventional and CNC applications

• ISO‑normed rhombic insert, 80° geometry
• LX11 carbide grade for wear resistance
• 0.8 mm corner radius for fine finishing
• Compatible with standard turning holders

Predictable geometry for consistent surface finish and tool life

The ISO-standard rhombic geometry with an 80° included angle combines cut stability with access to confined features. A 0.8 mm corner radius reduces vibration at the cutting edge while enabling a fine surface finish on shafts and shoulders. This geometry supports controlled chip formation and predictable tool wear, which helps to reduce rework and minimise machine downtime. The relief angle of 0° provides a stable seating in the holder and contributes to repeatable cutting conditions.

Grade and material built for balanced wear resistance and toughness

Manufactured from tungsten carbide and specified with the LX11 Tungaloy grade, the insert is designed to balance wear resistance and edge toughness. LX11 complements the geometry by maintaining a stable cutting edge under varying cutting forces, making the insert suitable where a compromise between durability and reliability is required. The result is longer intervals between indexings and fewer tool changes, improving throughput on series turning tasks without sacrificing dimensional control.

Workshop integration and application guidance for smooth planning

The insert is delivered in the ISO series for turning and has a plate size of 12 mm with a plate thickness of 7.94 mm, presented without a centre hole and without a chipbreaker. Compatibility with a holder is determined by form, relief angle, tolerance class, fastening method, size and thickness; selecting the matching outer holder or boring bar ensures correct clamping and thermal behaviour. For external and internal turning, choose the appropriate holder geometry and, where necessary, a chipbreaker and grade that suit the workpiece material to achieve stable material removal and consistent surface quality.

FAQ

What machining tasks is this insert best suited for? This insert is optimised for turning operations; the CNGN120708 LX11 insert performs well on external and internal turning where a balance of wear resistance and toughness is required.

How does the LX11 grade affect performance? The LX11 grade from Tungaloy provides a compromise between wear resistance and edge stability, enabling longer tool life and reliable performance under varying cutting loads.

Which holders are compatible with this insert? Compatibility depends on holder form, relief angle, tolerance class, fastening, size and thickness; selecting a holder that matches the insert’s rhombic form and 7.94 mm thickness ensures correct clamping.

Can this insert be used for finishing and semi-finishing passes? Yes; the 0.8 mm corner radius and stable edge provided by the LX11 grade make the insert suitable for fine finishing and controlled semi-finishing in turning operations.
