TNMG160408-MM5 WSM20S turning indexable insert — Tiger·tec Silver, MM5 chipbreaker (Walter Tools)

A TNMG160408-MM5 WSM20S turning indexable insert designed for reliable chip control and durable cutting performance in stainless steels and heat‑resistant superalloys

• Tiger·tec Silver coated carbide
• For stainless steels and superalloys
• Triangle 60° with 0.8 mm corner radius
• MM5 chipbreaker for stable chip control

Higher cutting reliability with optimised grade and coating

The combination of the Tiger·tec Silver coating and the WSM20S grade delivers a robust, coated carbide solution tailored to the demands of stainless steels and superalloys. This material pairing supports consistent chip formation and resistance to built-up edge, reducing interruptions during series production. The solid, coated structure of the grade improves thermal and mechanical stability at the cutting edge, ensuring reproducible component quality and fewer insert changes per shift.

Geometry engineered for controlled cutting and tool life

The triangle 60° insert form with a 0.8 mm corner radius and negative rake 0° provides a balance between strength and cutting performance. The MM5 chipbreaker is designed to break and evacuate chips reliably when machining tough materials, lowering the risk of entanglement and protecting the toolholder and workpiece surface. As a result, the geometry supports steady metal removal rates and gives predictable tool wear characteristics, which simplifies process planning in mixed‑material production.

Process benefits and shop‑floor integration

With tolerance class M and a compact plate size, this insert fits typical clamping systems for turning operations and is suited to both semi‑finishing and finishing tasks in demanding alloys. The grade’s focus on high edge stability reduces rejects and improves overall equipment effectiveness. For production planners, the insert offers a pragmatic combination of performance and repeatability that helps to shorten machining cycles and maintain component integrity across batches.
