CNGA 120408 LX10 turning insert – Tungaloy

The CNGA 120408 LX10 is an ISO-standard, rhombic indexable turning insert designed for external and internal turning applications with a cylindrical locating hole.

• ISO-compatible rhombic indexable insert
• LX10 Tungaloy grade for wear resistance
• 80° geometry with 0° clearance
• 0.8 mm nose radius for mixed turning

Consistent cutting geometry for repeatable results

The CNGA 120408 LX10 indexable insert offers an 80° rhombic geometry and a 0° clearance that together deliver stable tool engagement and predictable cutting behaviour. Manufactured in carbide and finished for accuracy, the insert maintains cutting-edge position under varying loads; the cylindrical hole ensures repeatable seating and clamping in compatible holders. This combination reduces variability in batch production and supports tighter tolerance holding, which is particularly relevant for automotive and general engineering turning tasks.

LX10 grade and material benefits for improved productivity

Engineered with the LX10 Tungaloy grade, the insert balances wear resistance and toughness to extend cutting life while maintaining edge stability. The carbide substrate provides thermal and mechanical strength for continuous machining, while the chosen grade supports a broad range of workpiece materials when matched with the correct chipbreaker and machining parameters. As a result, the system achieves higher uptime and lower tool-change frequency, contributing to a more economical machining process and predictable cycle times.

Compatibility, mounting and selection guidance

Compatibility with toolholders depends on form, clearance angle, tolerance class, clamping method, size and thickness; the CNGA 120408 is supplied in an ISO size with a 4.76 mm plate thickness and a 12 mm inscribed circle, making it suitable for many standard external holders and boring bars. The 0.8 mm nose radius offers a compromise between edge strength and finish, while the lack of a chipbreaker in this specification means the insert should be paired with an appropriate geometry and cutting data for the workpiece material. For secure assembly, use the correct underlay plate, clamp set and replacement screw specified by the holder manufacturer to ensure process safety.

FAQ

What holder types are compatible with this insert?
Compatibility depends on the holder form; the CNGA 120408 LX10 turning insert fits ISO-standard holders and boring bars designed for CNGA geometry and the specified plate thickness.

Which materials can be machined with this grade?
The LX10 grade on the CNGA 120408 insert is designed for a broad material range when the appropriate cutting data and chip control measures are applied.

Is there a chipbreaker included with this insert?
This CNGA 120408 variant is supplied without a chipbreaker; select a matching chip control geometry or insert variant when machining materials that require controlled chip formation.

How does the 0.8 mm nose radius affect surface finish?
A 0.8 mm nose radius provides a balance between edge strength and surface finish; it improves edge robustness while still allowing good surface quality in general turning operations.

What is the correct mounting procedure for secure clamping?
Use the designated underlay plate, clamp set and replacement screw specified for the holder; proper seating of the CNGA 120408 LX10 insert in the holder’s pocket and the cylindrical hole alignment ensure repeatable clamping and process stability.
