CNMG120408-NFT WS10 indexable turning insert — Rhombic 80°, 0° negative rake (Walter Tools)

The CNMG120408-NFT WS10 is a rhombic 80° indexable turning insert designed for general-purpose external turning, featuring a 0° negative rake and an NFT chipbreaker for controlled chip formation across a broad range of tasks.

Rhombic 80° geometry 0.8 mm corner radius NFT chipbreaker for stable chips Coated carbide WS10 grade

Boosted process stability through optimised chip control

The rhombic 80° geometry combined with the NFT chipbreaker delivers consistent chip formation and reduced risk of built-up edge in many turning applications. This geometry offers a good balance between cutting edge strength and accessibility for external profiling, while the chipbreaker design directs chips away from the cutting zone, reducing interruptions and downtime. The negative 0° rake increases edge robustness for interrupted cuts and heavy engagement, making the insert a practical choice where stable performance under variable cutting conditions is required. For engineers aiming to increase throughput, the focus on predictable chip behaviour supports smoother production cycles and fewer reworks.

Reliable wear resistance and economical life with WS10 grade

The insert is supplied in the WS10 coated carbide grade, a Walter Tools family type optimised for general turning tasks; this grade provides a combination of wear resistance and economical tool life. Coated carbide enhances heat resistance at the cutting edge, which permits sustained cutting speeds and contributes to lower tooling costs per part over longer production runs. When processing common engineering materials, selecting a coated carbide grade such as WS10 helps to maintain edge integrity and surface finish without frequent indexing, thus improving overall machining economy. For specific material compatibility, the product matrix should be consulted to match cutting data to component material.

Clear technical advantages for easier integration in turning processes

Key dimensions such as the 0.8 mm corner radius and the insert size ensure reproducible component radii and repeatable edge strength in serial production. The plate thickness and standardised ISO designation simplify toolholder selection and changeover, which supports leaner tool management in busy workshops. Because the insert follows established ISO naming, it integrates with existing toolholders and tool management systems without special adapters. When combined with a dependable toolholder and correct cutting parameters, the design reduces vibration sensitivity and improves surface quality, supporting measurable productivity gains.

FAQ

What does the NFT chipbreaker do on this insert? The NFT chipbreaker on the CNMG120408-NFT WS10 promotes controlled chip formation and efficient evacuation, which helps to reduce chip entanglement and maintain a steady cutting process during external turning.

Is the WS10 grade suitable for a wide range of materials? The WS10 coated carbide grade offers a balanced wear resistance suitable for many general turning tasks; however, the CNMG120408-NFT WS10 should be matched to the specific material via Walter Tools’ product matrix for best results.

How does a 0° negative rake affect cutting performance? A 0° negative rake increases edge strength and resistance to chipping, making the insert robust for interrupted cuts and heavier feeds; the CNMG120408-NFT WS10 benefits from this when stability is a priority.

Can this insert be used in standard CNMG toolholders? Yes, the ISO designation CNMG120408-NFT WS10 corresponds to standard CNMG geometry and will fit compatible CNMG toolholders that accept the specified insert size and thickness.

What is the recommended check before using the insert in production? Verify the cutting data for the target material and consult the product matrix for WS10 to ensure the cutting speed and feed are within recommended ranges for reliable tool life.
