RNGN120400TS-0 WBK20 – Indexable turning insert, CBN grade, round

The RNGN120400TS-0 WBK20 is a round indexable turning insert engineered for hard and highly abrasive turning tasks, offering a robust cutting edge for hardened steels and similarly demanding materials.

• CBN grade WBK20 for hard materials
• Round geometry for versatile turning operations
• 0° negative rake for high edge strength
• Tolerance class G for consistent fit

High-performance cutting in hard turning

The core advantage of this insert is its CBN composition: WBK20 is designed for machining hardened steels and other highly abrasive alloys where conventional carbides wear quickly. The combination of the CBN grade and a 0° negative rake increases edge stability and extends cutting life under elevated contact stresses, which translates into fewer tool changes and higher process uptime. In production environments with high component throughput, the result is measurable efficiency improvement and more predictable cycle times.

Geometry that supports repeatable results

The round plate form provides multiple usable cutting edges and smooth engagement in turning cycles, while the nominal corner radius of 0 permits precise profile control where a fine cutting line is required. The specified tolerance class G helps ensure a consistent fit in standard RNGN toolholders, reducing setup variability. These geometrical characteristics support machining strategies that focus on stability and reproducibility rather than aggressive roughing alone.

Material suitability and application notes

As a CBN solution, the grade is optimised for hardened steels and may be suitable for specific cast or superalloy applications depending on the exact workpiece and cutting parameters; consult the product matrix to confirm suitability for particular alloys. Because the insert is designed for high-wear tasks, attention to coolant strategy and cutting data will preserve edge life and surface finish. For complex or critical components, Metav Werkzeuge can provide application advice and data to align machining parameters with the insert’s capabilities.

Productivity, process security and brand reliability

Choosing a CBN grade from a recognised supplier supports process security and consistent results across batches. The insert’s specification aims to reduce unplanned downtime by offering a robust edge geometry for demanding turning operations, contributing to improved overall equipment effectiveness. Backed by the manufacturer’s reputation, users can expect consistent quality and repeatable performance for serial production tasks.

FAQ

Which materials is this insert best suited for?
The RNGN120400TS-0 WBK20 uses a CBN grade suited primarily to hardened steels and other highly abrasive materials; suitability for cast components or superalloys should be verified against the product matrix.

Can this insert achieve fine surface finishes?
The round geometry and zero corner radius support precise profile control and can deliver fine finishes when combined with appropriate cutting parameters and a stable setup.

How does the 0° negative rake influence performance?
A negative rake of 0° increases edge strength and resistance to mechanical shock, making the insert more tolerant to interrupted cuts and hard workpiece surfaces.

Is the RNGN geometry compatible with standard toolholders?
Compatibility depends on the holder seat for RNGN-style inserts; the tolerance class G and plate size indicate intended fit, but verification with the toolholder specification is recommended.

What assurances are there regarding consistency and quality?
The insert’s design and WBK20 CBN grade focus on wear resistance and repeatable performance, supported by the manufacturer’s process expertise and material development.
