RPGN090300T01020 WIS30 turning and milling indexable insert, 11° free angle — Walter Tools

A RPGN090300T01020 WIS30 indexable insert engineered for high-speed ceramic cutting in suitable ISO material groups for both turning and light milling applications.

• SiAlON cutting ceramic for high cutting speeds
• 11° free cutting angle for secure chip flow
• Round form, size 09 for versatile milling and turning

High-speed ceramic performance that raises productivity

The WIS30 grade is a SiAlON cutting ceramic developed for high cutting speeds and thermal resistance; this enables shorter cycle times where the ISO material group and cutting strategy permit. Ceramic grades such as this are designed to tolerate elevated temperatures and maintain edge integrity when used under appropriate conditions. Machining strategies must be aligned with the workpiece material and machine rigidity, since ceramic inserts favour stable, high-speed approaches rather than heavy interrupted cuts. The result is a significant potential increase in throughput when the process is configured correctly.

Precision geometry for repeatable chip control and surface quality

The insert’s geometry, including the 11° free cutting angle and round form, contributes to controlled chip formation and predictable tool contact. The designation carries a tolerance class G, which supports consistent seating and repeatable positioning in compatible toolholders. With a corner radius of 0, the edge geometry focuses on sharp engagement and minimal rubbing, which benefits surface finish in finishing passes. These geometric elements are central to converting the material properties of the grade into consistent part quality across batch production.

Practical selection guidance and application checks

This insert is suitable for both turning and milling tasks where a ceramic grade is specified; however, applicability depends on the concrete ISO material group indicated in the product matrix. The WIS30 series is presented as an open cutting-grade line by the manufacturer, and selection should be based on the workpiece material, machine capability and the intended cutting parameters. For varied production environments, the round form and size 09 offer flexibility in toolpath planning while the thin plate thickness (03) supports precise depth control. Consultation of the manufacturer’s matrix ensures the grade choice matches the intended material and process.

FAQ

Which materials are best suited for this insert?
The RPGN090300T01020 WIS30 insert uses a SiAlON ceramic cutting grade and is intended for high-speed machining where the specific ISO material group matches the grade; suitability should be confirmed via the product matrix.

Can the insert be used for both turning and milling operations?
Yes, the designation specifies turning and milling capability for the insert, and the round form supports versatile applications in both processes when cutting parameters are adjusted for ceramic performance.

What does the WIS30 grade indicate?
WIS30 identifies a Walter Tools SiAlON ceramic grade formulated for temperature-resistant, high-speed cutting; exact application limits are determined by the ISO workpiece group.

How does the 11° free angle affect cutting?
The 11° free angle reduces rubbing and improves chip flow under appropriate cutting conditions, helping to maintain edge life and surface quality in high-speed applications.

Is a coating listed for this insert?
No coating is specified in the available data for this grade; the product is characterised by its SiAlON ceramic composition rather than an additional coating.
