CNMG 120408 GH330 Tungaloy indexable insert — rhombic ISO insert for turning, double‑sided chipbreaker

The CNMG120408 GH330 is an ISO‑standard rhombic indexable insert designed for external and internal turning operations, offering wear‑resistant performance in a compact, easy‑integrate format.

• ISO‑standard CNMG format
• GH330 grade for wear resistance
• Double‑sided chipbreaker
• Rhombic form with 0.8 mm nose radius

Reliable wear resistance and consistent tool life

The GH330 grade is a Tungaloy carbide formulation engineered to balance wear resistance and toughness. On materials where edge stability is critical, this composition prolongs the tool life and reduces the frequency of insert changes. Carbide substrates provide a hard, heat‑resistant cutting edge while the grade and geometry protect against chipping; this results in fewer interruptions and more predictable process windows for turning applications.

Seamless integration with ISO‑compliant toolholders

As an ISO‑standard insert, compatibility is ensured by matching the insert form, 0° clearance angle, tolerance class, clamping method, size and thickness to the chosen holder. The rhombic shape combined with a cylindrical hole allows secure seating and straightforward replacement in standard external holders and boring bars. This reduces set‑up time and supports swift changeovers across batches, helping to maintain stable production flow on mixed‑series turning operations.

Precision finish and efficient chip control

The double‑sided chipbreaker geometry offers controlled chip formation for a broad range of steels and alloys, which contributes directly to improved surface finish and safer machining. A 0.8 mm nose radius supports fine contouring and repeatable dimensional results, while the 4.76 mm thickness increases stiffness under load. Efficient chip control lowers the risk of built‑up edge and improves reproducibility when machining both external diameters and internal bores.

FAQ

What materials is this insert suitable for machining?
The CNMG120408 GH330 insert is formulated for a wide range of turning tasks; the GH330 grade provides balanced wear resistance and toughness for common steels and similar alloys.

How does the double‑sided chipbreaker benefit production?
A double‑sided chipbreaker on this insert extends indexable life and ensures consistent chip control, which improves surface finish and reduces handling of swarf in automated or manual turning processes.

Is the insert compatible with standard CNMG toolholders?
Yes; as an ISO‑standard CNMG insert, compatibility depends on matching form, clearance angle, tolerance class, clamping and thickness to the selected holder or boring bar.

What dimensional features support fine finishing?
The 0.8 mm nose radius and 4.76 mm plate thickness provide the rigidity and form required for precise contouring and repeatable dimensional accuracy during finishing passes.

Which catalogue or SKU should be quoted when ordering?
Refer to the manufacturer article number 6802099 or the manufacturer SKU TUN6802099 when placing orders for the CNMG120408 GH330 indexable insert.
