CNGN 120404 LX11 Tungaloy turning insert — rhombic 80° geometry

The CNGN120404 LX11 is an ISO‑standard rhombic turning insert designed for external and internal turning, offering a balanced combination of wear resistance and edge stability for general turning tasks

• ISO‑standard rhombic insert 80°
• Tungaloy LX11 carbide grade
• 0.4 mm corner radius
• 4.76 mm plate thickness

Predictable set‑up thanks to ISO geometry and form fit

The ISO designation ensures straightforward integration into a wide range of holders: compatibility is defined by insert form, relief angle, tolerance class, clamping method, size and thickness. With its 80° included angle and standard rhombic shape, the insert provides consistent contact geometry that simplifies fixture selection and reduces setup time. This predictability translates into fewer stoppages and better repeatability in serial turning operations, supporting stable production flows and easier tool inventory management.

Balanced cutting performance from the LX11 grade

The Tungaloy LX11 grade is formulated to combine wear resistance with sufficient toughness, helping to maintain a stable cutting edge over longer cycles. For turning applications, this balance reduces frequent edge changes and supports consistent surface finish on workpieces. The cemented carbide substrate and grade composition complement the insert geometry, producing reliable performance on varying turning tasks while preserving edge stability under typical industrial cutting conditions.

Practical mounting and selection guidance for reliable machining

The insert is delivered as an ISO indexable plate and requires a matching external holder or boring bar, plus a support shim or clamp set and replacement screws for the system assembly. Key dimensions—12 mm size, 4.76 mm plate thickness and 0.4 mm corner radius—help determine rigidity and finishing capability. Note that the insert is supplied without hole and without a chipbreaker, so selection of an appropriate holder and machining parameters must reflect the chosen workpiece material and desired chip control. Following these selection rules ensures efficient material removal and a steady tool life.

FAQ

What holders are compatible with this insert?
Compatibility is determined by the ISO form and dimensions; the CNGN120404 LX11 insert fits holders specified for CNGN‑form indexable turning inserts and must match the form, tolerance and clamping method.

Is this insert suitable for internal as well as external turning?
Yes, the geometry and grade are intended for both external and internal turning tasks when used with an appropriate external holder or boring bar.

What are the main benefits of the LX11 grade?
The LX11 grade provides a balanced combination of wear resistance and toughness, giving the insert good edge stability and prolonged cutting life in general turning applications.

Does this insert include a chipbreaker or mounting hole?
The insert is supplied without a chipbreaker and without a hole, so chip control depends on holder selection and machining parameters.

How does the 0.4 mm corner radius affect performance?
The 0.4 mm corner radius improves edge strength and provides a compromise between finish quality and robustness, suitable for a range of finishing and light roughing operations.
