Reliable grade and process stability for demanding alloys

The WSM20S grade, integrated in the Tiger·tec Silver family, is formulated to deliver thermal resistance and a stable cutting edge when encountering materials that tend to work-harden or retain heat. This results in fewer unexpected tool changes and improved batch-to-batch reproducibility. For production environments where consistency matters, the combination of a coated carbide grade and a dedicated chip control geometry reduces the risk of built-up edge and helps maintain dimensional stability over longer tool life cycles.

Geometry and chip control that minimise interruptions

The rhombic 35° shape, combined with the MM4 chipbreaker and a 7° relief angle, creates a cutting geometry that promotes predictable chip formation and evacuation. The modest corner radius (r0.4) supports a balance between edge strength and fine surface finish. In practice, this geometry reduces the frequency of interruptions caused by poor chip flow and simplifies set-up by delivering consistent cutting forces, which helps maintain machine stability and lowers cycle-time variability.

Coating and substrate technologies that extend performance

The coated-carbidic composition of this insert, classified under the Tiger·tec Silver series, brings enhanced resistance to thermal loading and abrasive wear. The WSM20S coating system is optimised for applications with elevated cutting temperatures and for materials prone to rapid edge degradation. As a result, the tool sustains a sharper cutting profile for longer, enabling higher productive cutting parameters with less compromise on surface integrity when machining rostfreier Stahl and heat-resistant superalloys.

Practical integration into production workflows

Tolerance class G and the standardised ISO designation ease integration into existing toolholders and process documentation. The insert’s dimensions and codes follow established turning conventions, simplifying inventory and tool-change procedures. Procurement and process planners will value the predictable life and clear material suitability information, while workshop personnel benefit from a design that supports straightforward chip control and a reduction in rework due to improved surface quality.

FAQ

Which materials is this insert suitable for?
The VCGT160404-MM4 WSM20S from Walter Tools is intended for machining rostfreier Stahl and heat-resistant superalloys; the WSM20S grade and Tiger·tec Silver coating support stable cutting in such alloys.

How does the MM4 chipbreaker affect performance?
The MM4 chipbreaker on the insert directs chip formation into manageable segments, improving evacuation and reducing the risk of entanglement; this contributes to steadier cutting forces and fewer process interruptions.

What are the key geometric specifications to note?
The insert features a rhombic 35° form, a relief angle of 7°, and a corner radius of r0.4, which together balance edge strength with surface finish requirements for demanding turning operations.

Is the insert coated and what benefit does that bring?
Yes, the insert uses the Tiger·tec Silver coating system on a coated-carbide substrate (WSM20S), which increases thermal and abrasive resistance for longer tool life when machining high-temperature alloys.

Can this insert be used in standard toolholders?
The ISO designation and tolerance class G align the insert with common toolholder interfaces, facilitating straightforward replacement and inventory handling under standard turning setups.
