CNMA120408-RK5 WSM01 turning insert — Rhombic 80°, RK5 chipbreaker — Walter Tools

The CNMA120408-RK5 WSM01 is a rhombic 80° turning insert engineered for cutting rostfreier Stahl and heat‑resistant superalloys under high thermal and mechanical stress.

• Tiger‑tec Silver coating for heat resistance
• RK5 chipbreaker for secure chip control
• Rhombic 80° geometry for versatile turning
• Optimised for rostfreier Stahl and superalloys

High‑performance grade for extended tool life

The combination of the WSM01 grade within the Tiger‑tec Silver series provides a wear‑resistant, coated carbide substrate that mitigates friction and heat build‑up during heavy cutting. This engineered coating supports stable chip formation and protects the cutting edge against abrasive and adhesive wear common when machining rostfreier Stahl and heat‑resistant superalloys. As a result, the insert delivers longer edge life and fewer tool changes, directly improving machine utilisation and lowering cost per component.

Geometry that balances strength and surface quality

The Rhombic 80° geometry together with a 0.8 mm corner radius and a 0° (negative) rake produces a robust cutting edge suited to both interrupted cuts and continuous turning. The larger corner radius increases edge strength and supports a consistent surface finish in finishing passes, while the negative rake angle reinforces the cutting edge for heavy‑duty roughing. The insert’s thickness code 04 contributes to rigidity on the toolholder, helping to reduce vibration and improve dimensional stability on the workpiece.

Optimised chip control for predictable production

The RK5 chipbreaker is designed to form short, controllable chips when machining ductile and gummy materials. Good chip control reduces machining interruptions, minimises rework and enhances process stability — particularly important for rostfreiende Stahl that tends to produce stringy chips. With improved chip evacuation and fewer unforeseen stoppages, cycle times become more predictable, supporting tighter production schedules and higher throughput.

Suited applications and economic benefits

This insert is ideal for external turning operations where a balance of durability and surface quality is required: from heavy roughing to light finishing in rostfreier Stahl and heat‑resistant superalloys, with potential for titanium depending on the chosen tooling combination. Selecting this grade and geometry can reduce the total number of inserts used per part and lower dressing or rework operations, yielding measurable savings over production runs. If clarification is required on matching the insert to a specific machine or workpiece material, Metav Werkzeuge provides application support and tooling advice.

FAQ

What materials is this insert intended for?
The CNMA120408-RK5 WSM01 is intended primarily for rostfreier Stahl and heat‑resistant superalloys; depending on the chosen holder and parameters it can also be used for titanium applications.

What advantage does the RK5 chipbreaker provide?
The RK5 chipbreaker on the CNMA120408-RK5 WSM01 produces controlled, short chips to improve evacuation and reduce interruptions during turning operations.

How does the Tiger‑tec Silver series affect performance?
Tiger‑tec Silver coating enhances thermal resistance and wear protection on the CNMA120408-RK5 WSM01, supporting longer edge life and consistent cutting under elevated temperatures.

Which cutting tasks is the Rhombic 80° geometry best for?
The Rhombic 80° shape of this insert is versatile for external turning tasks, offering a balance between accessibility, edge strength and reliable surface finish.

How to decide between finishing and roughing with this insert?
Use the CNMA120408-RK5 WSM01 with a light depth of cut and lower feed for finishing to exploit the 0.8 mm corner radius; select heavier depths and conservative feeds for roughing to benefit from the negative rake and robust edge geometry.
