CNMM120412-HU5 WSM30S turning insert — Walter Tools, Tiger‑tec Silver, 0° (negativ), R=1.2

The CNMM120412-HU5 WSM30S is a coated carbide indexable turning insert optimised for demanding turning tasks in rostfreier Stahl and heat‑resistant superalloys, combining a proven chipbreaker geometry with the Tiger‑tec Silver coating technology for reliable chip control.

• Robust Tiger‑tec Silver coating
• Negative 0° rake for edge security
• Rhombus 80° form for versatile turning
• Corner radius 1.2 mm for stable cuts

Reliable cutting in rostfreier Stahl and superalloys for consistent results

The WSM30S grade from the Tiger‑tec Silver family is engineered for materials that generate heat and tend to work‑harden, notably rostfreier Stahl (ISO group M) and heat‑resistant superalloys/titanium (ISO group S). The coated carbide construction increases thermal resistance and reduces adhesive wear, while the HU5 chipbreaker promotes predictable chip formation. This combination yields fewer process interruptions and a steadier surface finish, which supports improved machine utilisation and repeatable part quality.

Geometry and edge features that protect the cutting edge

The rhombic 80° insert shape and a corner radius of 1.2 mm deliver a balance between strength and versatility for external and light profiling operations. The 0° (negativ) relief angle enhances edge security under interrupted cuts and heavy engagement, and the HU5 chipbreaker is designed to control chip flow in tough alloys. Translating these features into shopfloor benefits means longer intervals between indexings and greater resistance to edge chipping during medium‑to‑heavy duty turning.

Coating and grade for extended tool life and process security

The WSM30S grade, a coated carbide within the Tiger‑tec Silver series, focuses on stable wear behaviour and broad material coverage. The coating reduces friction and protects the cutting substrate at elevated temperatures, which pays off in longer tool life and fewer replacements. From a cost‑efficiency perspective, improved life and fewer stops result in lower effective tooling cost per part and a more predictable production rhythm.

Practical application notes and machine compatibility

The CNMM120412‑HU5 insert is suited to standard indexable turning holders that accept the 12‑size rhombic format and a thickness code of 04; the insert designation indicates the HU5 chipbreaker and the WSM30S grade for heat‑resistant materials. The insert is particularly effective in operations where chip control and edge stability are priorities, such as semi‑finishing and heavier finishing passes in rostfreier Stahl. For holders and clamping details, match the CNMM ISO form and the 80° geometry to ensure correct seating and secure clamping.
