CNGG120408-NFT WS10 — Indexable turning insert, rhombic 80°, 0.8 mm corner radius (Walter Tools)

CNGG120408-NFT WS10 is an indexable turning insert designed for medium to heavy turning operations where reliable chip control and edge stability are required

• Rhombic 80° insert geometry
• 0° negative rake for heavy cuts
• 0.8 mm corner radius for edge strength
• NFT chipbreaker for controlled chips
• WS10 coated carbide grade

Reliable productivity for demanding turning tasks

The indexable insert delivers a balance of toughness and wear resistance thanks to the WS10 coated carbide grade. The rhombic 80° geometry provides a secure cutting edge for shoulder and profile turning while the 0° negative rake enhances tool robustness under interrupted cuts and heavier feeds. This combination reduces the need for frequent edge changes and supports continuous production flows. The design is intended for operations where tool life and predictable behaviour are more important than extremely fine finishing passes.

Secure chip control and durable cutting edge

Equipped with the NFT chipbreaker, the insert controls swarf reliably, which lowers the risk of entanglement and shortens cycle interruptions caused by manual chip clearing. The 0.8 mm corner radius increases edge strength, improving resistance to mechanical stress and chipping during roughing. In practice, this means fewer unplanned stoppages and steadier component tolerances, particularly on medium-duty turning tasks. For holders that accept rhombic 80° inserts, this geometry also helps to stabilise the cutting forces, contributing to consistent surface quality.

Practical selection and process advice for toolrooms

The insert code reflects key dimensions: an inscribed circle of 12 mm and a thickness code 04, plus the rhombic 80° form and NFT chip control. These attributes simplify toolholder selection and inventory management by matching common carrier systems. For material-specific suitability consult the WS10 product matrix in the catalogue: the grade is a coated carbide solution intended for broad material coverage. For tailored recommendations or clarification on suitable holders and cutting data, Metav Werkzeuge provides technical guidance and cutting-parameter support to help integrate the insert into existing processes.

Stability, reputation and application scope

Manufactured under the Walter Tools umbrella, the insert benefits from established development in cutter geometry and coating practice, promoting process stability and repeatable results. The combination of a robust edge geometry and a dedicated chipbreaker supports productive machining across a range of turning tasks where tool life and consistent component quality are priorities. For workshops seeking reliable performance in general turning and profile operations, this insert represents a pragmatic choice that emphasises reproducibility and practical machinability.

FAQ

What does the code CNGG120408-NFT indicate?
CNGG120408-NFT designates an indexable turning insert with a rhombic 80° form, inscribed circle 12 mm, thickness code 04, corner radius 0.8 mm and the NFT chipbreaker; the WS10 suffix identifies the coated carbide grade.

Which workpiece materials suit this insert?
Material suitability should be checked against the WS10 product matrix, but as a WS10 coated carbide grade the insert is intended for broad material coverage and general turning applications.

How does the NFT chipbreaker benefit production?
The NFT chipbreaker is designed to produce short, controlled chips which reduce entangling and clearing time, improving cycle reliability when using the CNGG120408-NFT WS10 insert.

Is the insert appropriate for interrupted cuts?
Yes — the 0° negative rake and 0.8 mm corner radius provide enhanced edge strength and robustness for interrupted or heavier cutting conditions when used in compatible toolholders.
