CNGN 120408 LX11 ISO indexable turning insert, rhombic 80° form — Tungaloy

CNGN 120408 LX11 is an ISO‑standard indexable insert designed for general turning applications, offering a balanced combination of wear resistance and cutting‑edge stability for external and internal turning.

• ISO‑standard geometry
• Tungaloy LX11 grade
• Rhombic 80° form
• 0.8 mm corner radius

Greater productivity through a wear‑resistant grade

The LX11 grade, implemented in a tungsten carbide substrate, is engineered to balance wear resistance and toughness, reducing edge chipping during intermittent cuts. By choosing a grade that complements the insert geometry, process windows widen and tool changes become less frequent, which directly improves machine uptime. The ISO‑standard design ensures predictable seating and clamping in established toolholders, simplifying tool life management and stock control.

Precision fit and predictable machining behaviour

Compatibility with the toolholder is defined by form, clearance angle, tolerance class, fastening, size and thickness; the rhombic shape with an 80° approach angle and 0° clearance delivers stable cutting forces for facing and turning operations. The insert's 4.76 mm thickness and 12 mm size provide rigidity in the tool assembly, while the specification of no hole and no chipbreaker calls for matching holder and clamping components. Clear dimensional standards enable simple qualification in production environments, lowering setup time and variation.

Stable cutting edge and defined surface outcomes

A 0.8 mm corner radius offers a compromise between edge strength and surface finish: it resists edge breakdown on heavier passes while still permitting good surface quality on finishing cuts. The absence of an integral chipbreaker means chip control must be planned through toolpath, cutting parameters or matching clamping accessories; this flexibility allows the insert to be tailored to diverse applications. The result is repeatable component quality and a stable cutting process that supports efficient production.
