RPGN120400T01020 WIS30 — Indexable insert for turning and milling, SiAlON ceramic, 11° clearance, Walter Tools

RPGN120400T01020 WIS30 is a round indexable insert engineered for high-speed, temperature-resistant machining in demanding applications where ceramic grades bring clear performance advantages

• SiAlON ceramic grade for high speeds
• 11° clearance angle for stable cutting
• Round form for versatile tool paths
• 12 mm size for compact toolholders

Maximise process speed with ceramic cutting technology

The SiAlON-based grade delivers a clear advantage where high cutting speeds and heat resistance are required. As a ceramic cutting grade, WIS30 is designed to maintain edge integrity at elevated temperatures, which reduces the need for conservative speed reduction and enables shorter cycle times. This leads to improved throughput on finishing passes and productive roughing cycles where temperature control would otherwise limit cutting parameters. The round geometry additionally supports varied tool orientations, making the insert suitable for interpolated and profile milling as well as turning operations.

Consistent chip control and surface quality for reliable production

A generous 11° clearance angle helps to maintain consistent cutting conditions across the edge, reducing rubbing and promoting efficient chip formation with this insert. Stable chip formation is a decisive factor for consistent surface quality and repeatable dimensional results in series production. Where materials or process windows cause heat build-up, the grade’s thermal stability contributes to reduced edge wear and a lower tendency for built-up edge, which in turn supports predictable tool life and less frequent index changes.

Compact geometry for flexible toolset-ups and tool life economy

The insert’s round form and modest 12 mm size make it well suited to compact toolholders and multi-axis arrangements, delivering flexibility for tight setups or small-diameter tool bodies. The combination of a ceramic cutting edge and compact geometry supports longer intervals between interventions in many high-speed finishing tasks, translating into fewer tool changes and improved machine utilisation. For production environments focused on throughput, this can mean a measurable reduction in downtime and a more economical machining cycle overall.

Application guidance and compatibility notes for planners

Selection of ceramic grades always depends on the ISO workpiece group and the intended cutting strategy; refer to the product matrix for the specific workpiece class suitability before operation. The insert is intended for applications where heat-resistant cutting and higher speeds are priorities; for softer or highly ductile materials alternative grades may be preferable. For process planning, consult Metav Werkzeuge for recommendations on cutting data and matching toolholders to ensure optimal engagement and chip evacuation.

FAQ

What materials is this insert suited for? The RPGN120400T01020 WIS30 insert employs a SiAlON ceramic grade and is intended for high-speed, temperature-resistant machining; suitability must be checked against the product matrix for the specific ISO workpiece group.

How does the 11° clearance angle affect cutting? An 11° clearance angle reduces rubbing at the flank and supports stable chip formation with the ceramic grade, helping to preserve edge condition and improve surface finish during high-speed cuts.

Is this insert suitable for both turning and milling operations? Yes, the round geometry of the insert allows use in both turning and milling toolholders where the tooling system accepts the RPGN120400T01020 form and the process demands a ceramic cutting grade.

What should be checked before selecting this grade? Check the ISO workpiece classification and consult the Walter Tools product matrix for WIS30 to confirm material compatibility and recommended cutting data for the intended application.

Can this insert be used in interrupted cuts? Ceramic grades are generally sensitive to shock loads; evaluate the machining scenario for potential impact or interruptions and refer to Walter Tools guidelines and Metav Werkzeuge for application-specific advice.
