CNMG160612-MM5 WSM30S indexable turning insert – Tiger‑tec Silver for stainless steels (Walter Tools)

The CNMG160612-MM5 WSM30S is a rhombic 80° indexable turning insert with Tiger‑tec Silver coating, designed for productive machining of stainless steels and heat‑resistant superalloys.

• Tiger‑tec Silver coated grade WSM30S
• Suitable for stainless steels and superalloys
• Rhombic 80° geometry, 1.2 mm corner radius
• MM5 chipbreaker for stable chip control

High performance grade for demanding materials

The WSM30S grade, part of the Tiger‑tec Silver family, is a coated carbide designed for sustained performance when machining challenging alloys. Its formulation promotes stable chip formation under thermal stress and supports a durable cutting edge, which directly translates into longer tool life and fewer index changes. For operations that prioritise throughput and repeatable results, the combination of the coated grade and the insert geometry delivers measurable improvements in process security and surface integrity.

Geometry and chip control that protect the workpiece and tool

The rhombic 80° shape with a 1.2 mm corner radius and the MM5 chipbreaker balance strength and surface quality. The small but robust corner radius helps maintain a consistent cutting line and improves resistance to mechanical shock, while the MM5 chipbreaker is optimised to control chips from ductile, heat‑generating materials. The 0° negative rake geometry increases edge stability in interrupted cuts and heavy feeds, reducing the risk of build‑up and extending the interval between regrinds or index changes. These features together support a smoother machining cycle and improved component finish.

Practical benefits for the workshop and process planners

Chosen for tasks on stainless steels and heat‑resistant superalloys, this insert supports high process reliability and predictable tool behaviour in series production and single‑part machining alike. The insert’s designation and tolerance class minimise setup ambiguity, easing tool changeover and stock management. For engineering departments seeking to standardise inserts across multiple machines, the CNMG160612-MM5 WSM30S offers consistency in edge life and chip control that helps reduce scrap rates and stabilise cycle times.
