CNGA120420 LX11 Tungaloy turning insert (rhombic CNGA)

CNGA120420-LT LX11 Tungaloy insert for ISO-standard turning applications, designed for both external and internal turning when matched with a suitable holder

• ISO-standard CNGA insert for turning
• Tungaloy LX11 grade for edge stability
• Rhombic 12 mm form with cylindrical hole
• 4.76 mm thickness and 0° clearance angle

Reliable performance from a wear-resistant grade

The indexable insert is manufactured from carbide and supplied in the LX11 grade from Tungaloy, providing a balance of wear resistance and edge toughness suited to a wide range of turning tasks. This combination reduces flank wear in continuous machining and maintains a stable cutting edge under moderate interruption. Choosing a grade with the right mix of hardness and toughness extends tool life and helps stabilise cycle times, which in turn supports predictable process planning and lower tooling costs per component.

Precise ISO fit for quick integration into tool systems

As an ISO-standardised rhombic insert, compatibility with the toolholder is governed by form, clearance angle, tolerance class, fastening, size and thickness. The standardised geometry simplifies holder selection and replacement logistics, minimising downtime. The presence of a cylindrical hole and the specified form ensure reliable clamping and repeatable seating, which benefits shops that require quick index changes and reproducible positioning for batch production.

Geometry tailored to common turning tasks

The rhombic 12 mm shape with a corner radius of 2 mm and 0° clearance angle offers a versatile profile for both finishing and light roughing, depending on the machine setup and feed choices. The LT chipbreaker variant supports controlled chip formation in a variety of steels and general-purpose materials, improving surface integrity and helping evacuate chips from the cutting zone. The 4.76 mm thickness provides a low-profile option that suits smaller holders while retaining sufficient strength for stable cutting.

Practical system approach for operational reliability

This insert is part of an ISO-compatible system: insert, matching external holder or boring bar, backing/clamping set and replacement screws. Selecting the correct chipbreaker and grade in relation to component material and machining stability pays off in consistent surface quality and fewer unscheduled tool changes. Where process stability is critical, the Tungaloy LX11 grade gives an economical balance between edge life and resistance to edge chipping, supporting predictable production runs.

FAQ

What materials is this insert suitable for?
The CNGA120420-LT LX11 Tungaloy insert is a carbide grade intended for general turning; the LX11 grade offers versatility across a broad range of steels and general workshop materials.

How does the LT chipbreaker affect machining?
The LT chipbreaker on the CNGA120420-LT promotes controlled chip formation and evacuation, which helps to maintain surface finish and reduces the risk of chip-related interruptions in turning operations.

Will this insert fit my existing ISO CNGA holder?
Compatibility depends on form, clearance, tolerance class, fastening, size and thickness; the CNGA120420-LT follows ISO conventions, so it is compatible with holders specified for CNGA inserts of the same size and thickness.

What advantages does the LX11 grade provide?
Tungaloy’s LX11 grade combines wear resistance and edge stability, improving tool life under common turning conditions and supporting repeatable results across production batches.

Which components are required to assemble the cutting system?
A proper system comprises the indexable insert, a matching external holder or boring bar, a backing/clamping set and the designated replacement screws for secure fastening.
