CNMM190612-HU5 WSM30S Rhombic 80° turning insert by Walter Tools — coated carbide for stainless steel and superalloys

The CNMM190612-HU5 WSM30S is a rhombic 80° turning insert engineered for heavy‑duty machining of stainless steel and heat‑resistant superalloys, combining a Tiger·tec Silver coating with a stable HU5 chipbreaker for dependable chip control.

• Tiger·tec Silver coating for wear resistance
• WSM30S grade for stainless steels and superalloys
• Rhombic 80° form for versatile turning operations
• 0° negative rake for heavy‑cut stability

Enhanced productivity for stainless steel and heat‑resistant alloys

The coated carbide combination of Tiger·tec Silver and the WSM30S grade delivers a balance of thermal stability and wear resistance that is particularly effective when machining stainless steel and nickel‑based alloys. The material pairing reduces flank wear under elevated temperatures and supports stable cutting edges during medium to heavy cuts. As a result, cycle times can be shortened and tool change intervals extended, making the insert a rational choice for production environments where consistent throughput and process reliability are priorities.

Reliable chip control and edge stability for demanding cuts

The HU5 chipbreaker geometry is designed to promote predictable chip formation when cutting tough materials that tend to produce long, stringy swarf. Combined with a 0° (negative) free angle, the insert resists cutting‑edge deformation and minimises the risk of built‑up edge formation, which is typical when machining heat‑generating alloys. This controlled chip flow supports safer machining and reduces interruptions, translating into fewer secondary operations and improved overall equipment effectiveness.

Geometry that supports versatile turning strategies

The Rhombus 80° shape with a 1.2 mm corner radius provides a versatile compromise between strength and surface finish. The modest corner radius enables secure entry into interrupted surfaces and offers an improved tool life compared with finer radii, while still achieving a good surface quality on roughing passes. The insert’s format and thickness code allow compatibility with a wide range of toolholders, providing flexibility across turning applications in mixed‑material production cells.

Economic and operational benefits in production

Using a coated, industry‑graded insert such as this results in a favourable cost‑per‑cut metric: longer edge life and the Tiger·tec Silver coating reduce downtime for regrinds and replacements. When paired with suitable cutting data and coolant strategies, the insert contributes directly to lower tooling costs and higher machine uptime. For operations transitioning from general‑purpose grades to a specialised solution for stainless steel and superalloys, the change commonly yields measurable gains in productivity and surface quality.

FAQ

What materials is this insert suitable for?
The CNMM190612-HU5 WSM30S insert is specified for machining stainless steel and heat‑resistant superalloys; the WSM30S grade targets toughness and thermal stability for these groups.

How does the HU5 chipbreaker affect machining performance?
The HU5 chipbreaker on this Walter Tools insert promotes controlled chip formation during turning, improving swarf evacuation and reducing the risk of built‑up edge when working with difficult‑to‑machine alloys.

Is the insert geometry suitable for interrupted cuts?
Yes, the rhombic 80° form combined with a 1.2 mm corner radius gives the insert sufficient strength for interrupted surfaces while maintaining acceptable surface finish on roughing passes.

Does the negative free angle help with heavy cuts?
The 0° (negative) free angle increases cutting‑edge support and reduces the likelihood of edge chipping under high cutting forces, making the insert well suited to heavy and semi‑finishing operations.
