RPGN120400E WIS30 turning/milling indexable insert by Walter Tools — round shape, 11° relief

RPGN120400E WIS30 is a round indexable insert designed for high-speed turning and milling in the ISO material groups for which SiAlON ceramics are appropriate

• SiAlON ceramic grade WIS30 for high speeds
• 11° relief angle for stable cutting geometry
• Round plate, diameter 12 mm for versatile use
• Corner radius 0 for sharp profiling

Boosted throughput through high-speed ceramic cutting

The SiAlON-based WIS30 grade is engineered for high cutting speeds and thermal resistance, enabling shorter cycle times on suitable components. As a cutting-ceramic solution, this insert maintains a stable cutting edge at elevated temperatures, which translates into fewer interruptions for tool changes and a more predictable process rhythm. For production environments where machining speed and consistent surface quality matter, the use of a ceramic insert like this supports improved component throughput while keeping tool management straightforward.

Predictable process behaviour and integration into production

A round, indexable design with an 11° relief and a defined corner radius of 0 contributes to reliable chip formation and predictable tool engagement. The geometry minimises vibration in interrupted cuts and can simplify fixture and toolholder selection compared with non-indexable alternatives. Because the grade is specified as SiAlON ceramic, process parameters should be set according to the material group in the product matrix; this ensures stable wear behaviour and repeatable results across batches, improving overall process reliability.

Clear compatibility and practical application guidance

The insert is intended for machining tasks where ceramic grades are applicable; suitability depends on the target ISO material group. The designation RPGN120400E WIS30 identifies a round insert with a 12 mm diameter and thickness code 04, matched to Walter Tools’ open series of cutting grades. When selecting this ceramic insert, consider workpiece material, cutting speed and machine rigidity: ceramic grades excel in hard, high-temperature cuts but require sufficient stiffness and appropriate feeds to avoid chipping. Technical matching with the product matrix helps ensure the right combination of grade and geometry for the intended component.

FAQ

What materials is this ceramic grade suitable for? The WIS30 SiAlON grade is suitable for applications defined in the Walter product matrix; suitability depends on the specific ISO material group of the workpiece and should be checked against the grade recommendations.

Can the insert be used for both turning and milling operations? Yes, the RPGN120400E WIS30 is specified as a turning and milling indexable insert and its round form supports versatile engagement geometries for both operation types.

How does the 11° relief angle affect cutting performance? An 11° relief angle helps maintain a stable cutting geometry and supports predictable chip formation; this contributes to improved surface finish and process stability when combined with the right speed and feed settings.

Is technical matching available for specific parts or materials? Technical matching is recommended: Metav Werkzeuge can assist in selecting the correct grade and geometry for the application to ensure the best balance of tool life and part quality.
