CNMG120404-NFT WS10 — Walter Tools indexable turning insert, Rhombic 80°, 0° negative rake

The CNMG120404-NFT WS10 is a coated carbide indexable turning insert designed for general turning tasks where reliable chip control and repeatable performance are required

• WS10 coated carbide grade for varied materials
• NFT chipbreaker for controlled chip formation
• Rhombic 80° geometry for versatile turning
• 0.4 mm corner radius and 0° negative rake

Stable chip control that improves process reliability

The combination of the NFT chipbreaker with Walter's WS10 coated-carbide grade delivers consistent chip formation and reliable evacuation under a wide range of cutting conditions. This reduces the risk of built-up edge and interruptions in production, which in turn supports smoother machining cycles and lower scrap rates. For practical planning, the insert's chipbreaking geometry is particularly beneficial in medium-depth turning where controlled chips prevent entanglement and tool damage.

Geometry engineered for versatile turning tasks

The Rhombic 80° shape and 0° negative rake provide a balance between accessibility and stability on the workpiece, while the 0.4 mm corner radius offers an effective compromise between edge strength and surface finish. These geometric features allow a dependable entry angle on facing and profiling operations, and the insert thickness and dimensions suit standard CNMG-compatible toolholders. The robust edge form supports repeatable results in batch production and frequent tool changes.

Integration into production and technical considerations

With tolerance class M and the designation as an open series from Walter, the insert is built for consistent interchangeability and process integration. The cutting-material class is specified as coated carbide, but detailed workpiece suitability should be confirmed via the manufacturer's product matrix to match alloy, hardness and cutting parameters. Choosing the appropriate grade and cutting data will maximise tool life and surface quality while ensuring cost-effective machining.

FAQ

What materials is this insert suitable for?
The WS10 grade is a coated carbide family; specific suitability depends on the manufacturer's product matrix — the CNMG120404-NFT WS10 should be checked against workpiece alloy and hardness for optimal selection.

How does the NFT chipbreaker affect machining?
The NFT chipbreaker promotes controlled chip formation and evacuation, which improves process stability and reduces the likelihood of chip-related interruptions when using the CNMG120404-NFT WS10.

What does a 0° negative rake mean for cutting performance?
A 0° negative rake increases edge strength and resistance to chipping, offering greater stability under heavier cuts; this characteristic of the CNMG120404-NFT WS10 supports robust turning operations.

Is the insert compatible with standard holders?
The CNMG format indicates compatibility with CNMG-design toolholders; the CNMG120404-NFT WS10 is intended for CNMG-compatible clamping systems, subject to correct seat and fastening per toolholder specifications.
