RCMT0803M0-FM4 WSM20S turning insert (Round 08, 7°) by Walter Tools

The RCMT0803M0-FM4 WSM20S is a round turning indexable insert designed for machining rostfreier Stahl and high-temperature alloys, offering a coated-carbide grade for heavy-duty and heat-intensive turning applications.

• Tiger·tec Silver coating for high heat resistance
• Secure chip control with FM4 chipbreaker
• Optimised for rostfreier Stahl and superalloys
• Round 08 form with 7° clearance

High-temperature cutting performance for tough materials

The combination of the Tiger·tec Silver coating and the WSM20S grade provides consistent wear resistance and thermal stability when machining materials from the ISO groups M and S. This makes the insert particularly suited to rostfreier Stahl as well as heat-resistant superalloys and titanium, where high cutting temperatures and work-hardening tendency demand a coating that supports stable cutting edges. The specification emphasises process reliability and fewer tool changes, which contributes to improved machine utilisation and predictable cycle times.

Stable chip formation and improved surface quality

Equipped with the FM4 chipbreaker, the insert promotes controlled chip segmentation and evacuation in continuous or semi-continuous cutting regimes. Stable chip control reduces the risk of built-up edge formation and supports a consistent surface finish on workpieces made from rostfreier Stahl and similar alloys. As a result, downstream processes such as polishing or inspection face fewer rejects, and the introduction of this insert can contribute to lower overall machining costs through reduced rework and improved first-pass quality.

Geometry engineered for repeatable clamping and longer life

The round RCMT format (Round 08) with a 7° clearance angle and a thickness code of 03 delivers a robust cutting edge and straightforward seat positioning in compatible tool holders. The tolerance class M ensures close dimensional conformity, aiding repeatable indexing and predictable run-out behaviour. These geometric attributes translate into easier process set-up, stable cutting conditions when performing interrupted cuts, and extended edge life under moderate to heavy cutting loads.

Practical application notes for production environments

The insert’s balance of hardness and toughness, afforded by the WSM20S coated carbide, is intended for roughing to semi-finishing cuts in demanding materials. Selection of appropriate cutting parameters and coolant strategy is recommended to fully leverage the Tiger·tec Silver technology and the FM4 chip control; application advice is available from Metav Werkzeuge to match cutting speeds and feeds to machine capability. The overall effect is a productive tooling choice that supports process security and consistent component quality.

FAQ

What materials is this insert optimised for?
The RCMT0803M0-FM4 WSM20S insert is optimised for rostfreier Stahl and for heat-resistant superalloys and titanium, reflecting the S / M material grouping of the cutting grade.

Which chipbreaker is integrated and what benefit does it bring?
The FM4 chipbreaker on the insert promotes controlled chip formation and reliable evacuation, reducing built-up edge and improving surface finish in continuous and semi-continuous turning operations.

How does the Tiger·tec Silver coating affect tool life?
The Tiger·tec Silver coating increases thermal resistance and wear protection for the WSM20S grade, helping to maintain a stable cutting edge under elevated temperatures and extending usable edge life.

Is the insert suitable for interrupted cuts and profiling?
The round RCMT 08 form with a 7° clearance and tolerance class M provides robustness and repeatable seating, making it suitable for many interrupted-cut and profiling applications when paired with appropriate tool holders.

What information should be provided when ordering the insert?
When ordering, reference the full designation RCMT0803M0-FM4 WSM20S and the article number RCMT0803M0-FM4-WSM20S-WALTER to ensure correct grade, chipbreaker and geometry are supplied.
