CNMM120408‑HU5 WSM30S indexable turning insert — Tiger‑tec Silver, Rhombic 80°, 0° negative clearance — Walter Tools

A compact indexable turning insert CNMM120408‑HU5 WSM30S designed for robust turning of rostfreier Stahl and heat‑resistant superalloys in demanding production environments

• Tiger‑tec Silver coating for thermal stability
• Optimised HU5 chipbreaker for stable chips
• Rhombic 80° form with 0° negative clearance
• 12 mm inscribed size with 0.8 mm corner radius

High performance on rostfreier Stahl and superalloys

The WSM30S grade, integrated in the Tiger‑tec Silver family, is formulated for machining tough, heat‑sensitive materials where secure chip formation and edge stability are essential. With the designation CNMM120408‑HU5, the insert presents an inscribed size of 12 mm, a nominal thickness of 4.0 mm and a 0.8 mm corner radius, dimensions that support consistent contact with the workpiece and predictable wear behaviour. The coated carbide substrate improves thermal resistance and reduces tendency to build up material on the edge, which supports longer productive cutting intervals and fewer insert changes. This paragraph focuses on measurable performance advantages and material compatibility for process planners and toolroom engineers.

Geometry and chip control for steady production

The combination of the HU5 chipbreaker and the rhombic 80° form delivers dependable chip control and flexible approach angles for turning operations. The 0° negative clearance provides robust edge support and resistance to mechanical loading, which is particularly useful in interrupted cuts or unstable clamping conditions. The HU5 geometry promotes controlled chip segmentation in both continuous and semi‑continuous cuts, reducing the risk of chip entanglement and improving surface finish. For workshop supervisors and CNC programmers, these features translate into fewer stoppages and a more predictable machining cycle.

Applications, process stability and economical use

Engineered for the challenges of machining rostfreier Stahl and S‑class materials such as nickel‑based superalloys and titanium, this insert supports operations where heat generation and edge wear are limiting factors. The coated grade WSM30S emphasises thermal stability and consistent cutting behaviour, contributing to reliable dimensional accuracy and repeatability across batches. In practice, the insert is suitable for component turning in aerospace, energy and medical sectors where material strength and surface integrity are critical. By combining a proven coating technology with a stable chipbreaker and negative‑geometry design, the insert helps maintain throughput while protecting machine investment.
