CNGA120420-LT LX10 turning indexable insert by Tungaloy — rhombic ISO insert, 80° lead angle

The CNGA120420-LT LX10 is an ISO-compatible rhombic turning insert designed for external and internal turning, offering a balance of wear resistance and edge stability for standard machining tasks

• ISO rhombic form CNGA 80°
• LX10 Tungaloy carbide grade
• 2 mm corner radius for robust edges
• Cylindrical hole for secure clamping

Engineered for consistent turning performance

The rhombic ISO-standard geometry and LX10 Tungaloy grade provide a dependable platform for stable machining. The combination of a robust tungsten carbide substrate and the LX10 specification delivers enhanced edge stability and controlled wear behaviour, which reduces downtime from frequent edge changes. The LT chipbreaker is matched to common turning strategies and supports predictable chip formation, making tool life more consistent. For operations where repeatable surface finish and process security matter, the standardised form and tolerance ensure predictable seating and orientation in ISO holders.

Secure clamping and dimensional compatibility for repeatability

Designed with a cylindrical hole and a defined plate thickness of 4.76 mm, this rhombic insert fits a wide range of ISO-compatible holders when matched by form, relief angle and size. The 80° lead angle and 0° clearance combine to produce a stable cutting posture that helps maintain axial rigidity during external turning. The 2 mm corner radius offers a compromise between strength and finish, reducing the likelihood of edge chipping under interrupted cuts. Specified dimensions and the ISO designation allow clear holder selection and straightforward replacement without additional adjustment, supporting efficient tool changes and consistent part tolerances.

Practical guidance for material selection and machining strategy

Intended for turning, the insert is supplied in a tungsten carbide grade tuned for general productivity and edge life; the LT chipbreaker and grade selection should be matched to the workpiece material and the machining stability available. For less stable setups, select slower feeds and a larger nose radius to distribute forces; for stable, high-speed operations, the LX10 composition provides wear resistance that can extend the productive cutting time between indexings. The ISO format and clear specification simplify inventory management and make it easier to standardise inserts across multiple machines, reducing set-up time and supporting consistent process outcomes.

FAQ

What materials is this insert intended for?
The CNGA120420-LT LX10 insert is designed for turning tasks; the LX10 grade provides a balance of wear resistance and toughness and should be matched to the workpiece material and machining conditions for best results.

How does the LT chipbreaker affect machining?
The LT chipbreaker on this insert promotes controlled chip formation and evacuation during turning, improving process stability and reducing the risk of chip-related interruptions.

Which holder features are required for compatibility?
Compatibility depends on matching the insert form, relief (0° clearance), tolerance class, fastening method, size and thickness; the rhombic ISO form and cylindrical hole ensure secure clamping in ISO-compatible holders.

What benefits does the 2 mm corner radius provide?
A 2 mm corner radius increases edge strength for interrupted cuts and provides a good compromise between surface finish and tool robustness under varying cutting conditions.

Is the insert suitable for internal as well as external turning?
Yes, the ISO rhombic geometry and LX10 grade are suitable for both external and internal turning; selection of holder and cutting parameters should reflect the specific application.
