RNGN120700E WWS20 — round turning/milling insert, 12 mm, 0° negative — Walter Tools

The RNGN120700E WWS20 is a round indexable insert designed for high‑speed and temperature‑resistant turning and milling applications, offering a compact 12 mm diameter and a negative 0° rake for robust cutting.

• Ceramic cutting grade WWS20 for high cutting speeds
• Round 12 mm insert for stable chip control
• Negative 0° rake for robust machining

Increased productivity through a ceramic cutting grade

The WWS20 cutting‑ceramic is engineered for high cutting speeds and temperature‑resistant conditions, enabling cycles that can reduce machining time per workpiece without compromising surface quality. As a ceramic grade, it prioritises thermal stability and wear resistance, which translates into longer effective tool life under appropriate conditions. Because the grade is optimised for speed, the main economic benefit is higher throughput and consistent part quality when matched to suitable workpiece materials and cutting parameters.

Stable geometry for predictable results and easy integration

With a round form and a nominal size of 12 mm, this insert provides secure seating in round‑insert toolholders and reliable engagement during interrupted cuts. The 0 corner radius and a 0° negative rake contribute to a sturdy cutting edge that resists chipping under heavier feed or depth‑of‑cut excursions. The specified tolerance class G supports interchangeability and consistent fit in standard RNGN‑style pockets, reducing setup variability and machine downtime.

Practical application advice and compatibility notes

The insert is supplied in the Walter Schneidstoffsorte – Serie offen and the concrete material suitability must be verified against the product matrix; the grade is particularly suited to applications where thermal loads are high. The turning/milling insert is especially effective where short, high‑energy engagements are required and where a heat‑tolerant cutting edge benefits cycle stability. For selection, match the insert geometry with the correct RNGN‑compatible toolholder and confirm the workpiece material groups in the manufacturer’s matrix to ensure optimal performance.

For high‑speed or temperature‑critical applications, contact Metav Werkzeuge to match the Walter Tools RNGN120700E WWS20 insert to the exact machining task and to check current availability.

FAQ

What materials is this grade designed for?
The WWS20 cutting‑ceramic is formulated for high‑speed and temperature‑resistant machining; the RNGN120700E WWS20 should be matched to workpiece groups using the manufacturer’s product matrix to confirm suitability.

Which geometry characteristics influence tool behaviour?
The round shape, 12 mm diameter, 07 thickness, 0 corner radius and 0° negative rake of the RNGN120700E WWS20 create a robust edge form with predictable chip flow and good resistance to edge chipping.

Does this insert fit standard RNGN toolholders?
The insert follows the RNGN designation; compatibility requires an RNGN‑type round insert pocket of the corresponding size and tolerance class G to ensure secure clamping and repeatable positioning.

How does the ceramic grade affect productivity?
As a cutting‑ceramic, WWS20 permits higher cutting speeds and shows better thermal stability than many carbide grades, which can result in improved cycle times and consistent surface finish when applied within its recommended material groups.

What does tolerance class G mean for interchangeability?
Tolerance class G indicates the insert meets defined dimensional tolerances for consistent fitment; this supports reliable seating and repeatable tool offsets in production environments.
