CNMG120408-NRT WS10 – indexable turning insert with negative 0° relief and 0.8 mm corner radius, Walter Tools

CNMG120408-NRT WS10 is an indexable turning insert designed for general turning applications where robust cutting edges and consistent chip control are required

• Negative 0° relief for robust cutting edges
• 0.8 mm corner radius for consistent profile quality
• Rhombic 80° geometry for versatile approach angles
• NRT chipbreaker for dependable chip control

Stable chip control and secure cutting performance

The insert combines a targeted chip control solution with a reinforced cutting geometry. The NRT chipbreaker provides predictable chip formation and evacuation, reducing the risk of tangling and downtime. Combined with the negative 0° relief, the cutting edge offers increased mechanical strength, which is particularly useful for interrupted cuts or unstable setups. The substrate and coating are referenced as coated carbide WS10, a grade that balances wear resistance and toughness; compatibility with specific workpiece materials should be verified in the manufacturer’s product matrix for the best process settings.

Consistent component quality through defined geometry

The rhombic 80° shape and the 0.8 mm corner radius support steady dimensional control and repeatable surface finishes. The defined geometry reduces deflection at the cutting edge and helps maintain dimensional tolerances during serial production. The insert’s designation and tolerance class M indicate stable manufacturing tolerances, which simplifies fixture planning and toolpath strategies. For turning operations where edge life and part finish matter, the combination of geometry and grade promotes fewer reworks and a more predictable process window.

Economic machining and process reliability

By choosing an insert with a robust relief and a proven chipbreaker, shops can expect improved tool life and lower risk of unexpected failures, contributing to better overall machine utilisation. The insert’s series description — Walter Schneidstoffsorte, open series — signals a widely applicable grade; however, process optimisation (cutting data, coolant strategy, and feed rates) is recommended to unlock the best economy. The design supports both roughing and semi-finishing steps where a balance of wear resistance and toughness is required, offering a pragmatic route to higher productivity with controlled machining costs.

FAQ

What material is the WS10 grade intended for?
The WS10 designation indicates a coated carbide grade; specific material suitability should be checked in the Walter product matrix and matched to the machining task before selection.

How does the NRT chipbreaker affect machining?
The NRT chipbreaker is designed to produce controlled chips and facilitate evacuation, leading to fewer stoppages and more consistent cycle times with the CNMG120408-NRT WS10 turning insert (SKU CNMG120408-NRT-WS10-WALTER).

What does the insert code CNMG120408 indicate?
The code denotes the insert geometry and key dimensions: the geometry family (CNMG), a nominal size (12), the thickness code (04), and the corner radius code corresponding to 0.8 mm; this helps in selecting compatible toolholders and inserts.

Is the negative 0° relief suitable for interrupted cuts?
Yes; the negative 0° relief gives the cutting edge additional strength and resistance to impact, which is beneficial for interrupted or unstable cutting conditions when using an indexable turning insert.
