CNGA 120412 LX11 Tungaloy turning insert — rhombic 80° for general turning

The CNGA120412 LX11 Tungaloy indexable insert is a rhombic ISO insert designed for external and internal turning applications, offering a balanced combination of wear resistance and edge stability for a wide range of steels and cast materials.

• ISO‑standard rhombic insert, 80° cutting angle
• LX11 Tungaloy grade for wear resistance
• 1.2 mm corner radius for robust edge
• Cylindrical hole and 4.76 mm thickness

Consistent productivity through material and geometry

The combination of the LX11 Tungaloy carbide grade and the CNGA geometry provides a reliable balance between wear resistance and toughness, which supports longer tool life and fewer insert changes. The rhombic form with an 80° included angle and a 1.2 mm corner radius resists chipping under interrupted cuts and offers stable performance on conventional turning tasks. For operators transitioning from coated grades, LX11 is optimised to sustain edge condition while maintaining dimensional accuracy, reducing downtime associated with frequent tool adjustments.

Practical compatibility and mounting guidance

This insert conforms to ISO dimensions, so compatibility with indexable holders is determined by the insert form, clearance angle, tolerance class, clamping method, size and thickness. The CNGA120412 features a cylindrical hole for positive clamping and a plate thickness of 4.76 mm, which together ensure secure locating in standard ISO holders. When selecting a holder, match the insert seat and clamp to the ISO designation to guarantee repeatable positioning and to preserve the insert cutting edge during clamping and unclamping cycles.

Clear use cases and material applicability

Intended primarily for turning, the insert performs well in a broad spectrum of materials when paired with the appropriate cutting data and stability: from unalloyed and alloyed steel to certain cast irons, depending on cutting parameters. The absence of a dedicated chipbreaker on this variant means that cutting parameters and workpiece rigidity should be optimised to achieve effective chip control; pairing with an appropriate cutting fluid or optimised feed rates will improve chip formation and surface finish. For finishing passes the 1.2 mm radius supports a robust edge that still achieves acceptable surface quality.

Ease of selection and process benefits

Using ISO‑standard inserts simplifies inventory and toolchange procedures across multi‑machine shops. The Tungaloy carbide composition and the LX11 specification provide predictable wear characteristics, allowing process engineers to establish reliable tool change intervals and cutting data sheets. Fewer unexpected edge failures mean shorter machine idle times and a steadier production flow, supporting cost‑efficient machining through reduced scrap and rework.

FAQ

What materials is this insert suited for? The CNGA 120412 LX11 Tungaloy insert is designed primarily for turning and works well on a broad range of steels and certain cast irons when appropriate cutting data and rigidity are observed.

Does the insert include a chipbreaker? This variant is supplied without a chipbreaker; chip control should be achieved via cutting parameters, workpiece rigidity and, where appropriate, coolant.

How is the insert secured in a holder? The insert uses a cylindrical hole and ISO seating; secure clamping in a matching ISO holder ensures repeatable positioning and stable cutting performance for the CNGA120412 insert.

What advantages does the LX11 grade provide? The LX11 grade from Tungaloy offers an optimised balance of wear resistance and toughness, supporting steady tool life and reduced edge failures during typical turning operations.

Which geometric parameters influence holder selection? Holder compatibility is determined by insert form, clearance angle, tolerance class, clamping method, size and thickness; for CNGA120412, ensure the holder matches the rhombic CNGA seat and the 4.76 mm thickness.
