CNGN120720 LX11 CNGN Turning Insert — ISO rhombic 80° (Tungaloy)

A CNGN120720 LX11 indexable turning insert designed for ISO‑conforming external and internal turning applications, offering a rhombic 80° shape and a 0° relief angle for predictable cutting behaviour.

• ISO rhombic insert CNGN form
• Corner radius 2 mm for stable edges
• LX11 grade for wear resistance
• Carbide substrate for long tool life

Consistent cutting geometry for repeatable results

The rhombic CNGN shape with an included angle of 80° delivers a predictable engagement with the workpiece, which contributes to steady cutting forces and uniform chip formation. The 0° relief angle is defined to suit a wide range of turning operations, while the corner radius of 2 mm supports robust cutting edges that resist premature chipping. These geometric details translate into shorter set‑up times and more consistent part quality when the insert is used in appropriate ISO holders.

Robust grade and substrate for extended productivity

The LX11 grade, developed by Tungaloy, combines wear resistance and edge toughness to withstand interrupted cuts and varied material families. Backed by a carbide substrate, the insert maintains cutting performance over longer tool life compared with less wear‑resistant grades. The result is a reduced need for frequent insert changes and a higher overall productivity in batch turning or continuous production.

Clear guidance on compatibility and application

Compatibility with a chosen holder depends on form, relief angle, tolerance class, fastening method, size and thickness; the ISO designation ensures straightforward matching to standard toolholders. The insert is intended for turning and suits both external and internal turning tasks when the insert geometry, grade and cutting data are aligned with the workpiece material. Where chip control is critical, select a chipbreaker or grade appropriate to the material and process, noting this specific variant is supplied without a chipbreaker.

Practical benefits in the workshop and on the shop floor

Using a standardised ISO insert such as this reduces tooling complexity and simplifies inventory management. The combination of a rhombic form, 2 mm corner radius and LX11 composition supports robust machining of a broad range of steels and common alloyed materials, helping to increase uptime and stabilise part tolerances. For operators less familiar with insert selection, the predictable performance of an ISO‑conforming insert eases process transfer between machines and operators.

FAQ

What materials is this insert suited for?
The LX11 grade on a carbide substrate is formulated for broad material coverage; the insert is suitable for machining steels and many common alloyed materials when cutting data are adjusted accordingly.

How does the 0° relief angle affect cutting performance?
A 0° relief angle provides a neutral clearance suited to a variety of turning tasks; it delivers predictable engagement and is compatible with ISO holders specified for this geometry.

Is a chipbreaker included with this variant?
This specific CNGN120720 LX11 insert is supplied without a chipbreaker; chip control should be addressed through grade selection or alternative insert styles where required.

Which holder features must be checked for compatibility?
Compatibility is determined by insert form, relief angle, tolerance class, fastening method, size and thickness; ensure the chosen ISO holder matches these criteria.

What is the manufacturer article number and SKU?
The manufacturer article number is 6801902 and the SKU is 6801902‑Tungaloy for ordering and inventory reference.
