CNGA120408 CX710 Tungaloy indexable insert for turning — rhombic 80°

The CNGA120408 CX710 is an ISO rhombic indexable insert designed for external and internal turning on ISO-compatible toolholders.

• ISO rhombic insert CNGA 120408 CX710
• Cylindrical central hole for secure clamping
• 0° clearance for stable cutting geometry
• 0.8 mm corner radius for versatile turning

Reliable edge stability for continuous turning

The CX710 grade is a Tungaloy-developed cemented carbide composition optimised to balance wear resistance and edge toughness, resulting in longer tool life under varied cutting conditions. The rhombic 80° geometry and the 0.8 mm corner radius deliver a compromise between strength and versatility: the larger included angle reduces cutting edge stress while the radius supports consistent surface finish. For production environments where predictable tool performance matters, this combination reduces unplanned tool changes and enhances process reliability.

Easy integration into ISO tooling systems

Supplied in the ISO CNGA format (designation 120408), the insert fits ISO-compatible clamping systems when the holder matches the form, clearance and thickness requirements. The insert features a cylindrical central hole and a thickness of 4.76 mm, enabling secure fixation in standard top-clamp or screw-down holders. The ISO design and consistent tolerances simplify inventory management and replacement planning, allowing shops to adopt the component without redesigning the clamping solution.

Practical guidance for application and productivity

Intended for turning operations, the insert performs best when the correct chipbreaker and cutting parameters are chosen according to the workpiece and machining stability. The plate is supplied without an integrated chipbreaker, so selecting a matching chipbreaker geometry on the holder or an appropriate cutting strategy is important for efficient swarf control. Used sensibly within the machining window, the component supports productive metal removal with an emphasis on tool life extension and consistent surface quality.

FAQ

What applications is this insert suitable for?
This CNGA120408 CX710 insert from Tungaloy is intended for external and internal turning operations and is best used where a balance of wear resistance and edge stability is required.

What are the key geometric values of the insert?
The insert has a corner radius of 0.8 mm, an included angle of 80°, a clearance angle of 0° and a thickness of 4.76 mm, providing a robust cutting edge for general turning.

How is the insert clamped in a toolholder?
Clamping uses the central cylindrical hole together with the ISO CNGA seat form; secure fixation requires a compatible holder that matches the insert form, clearance and thickness.

Can this insert be used for different materials?
The CX710 cemented carbide grade delivers a compromise of toughness and wear resistance, making it suitable across a range of workpiece materials when paired with the correct chipbreaker and cutting parameters.

How can the correct replacement be identified?
Use the manufacturer article number 6816889 or the manufacturer SKU TUN6816889 to ensure the correct CNGA120408 CX710 Tungaloy insert is selected.
