DCMT070202-FW4 WSM20S indexable turning insert — Tiger·tec Silver, for stainless steels (Walter Tools)

The DCMT070202-FW4 WSM20S is an indexable turning insert engineered for machining stainless steels and heat‑resistant superalloys, combining a rhombic 55° geometry with a 7° clearance and a 0.2 mm corner radius for stable cutting and consistent surface finish

• Tiger·tec Silver coated grade WSM20S
• Optimised FW4 chipbreaker for stable chips
• Rhombic 55° shape with 0.2 mm corner radius
• Suited to stainless steels and superalloys

Consistent process security for difficult‑to‑cut materials

The coated cemented‑carbide grade WSM20S of the Tiger·tec Silver series is developed for high thermal and mechanical loads common when machining stainless steels and heat‑resistant alloys. The combination of coating technology and substrate enhances wear resistance and maintains a stable cutting edge, which reduces the frequency of index changes and helps achieve reproducible production results. This results in improved machine utilisation and predictable tool life when cutting demanding materials.

Improved chip control and surface quality with FW4 geometry

The FW4 chipbreaker and the rhombic 55° form provide controlled chip formation and evacuation in interrupted and continuous cuts. A defined 0.2 mm corner radius reduces edge chipping while supporting finish requirements; the modest 7° clearance angle minimises rubbing and contributes to a finer surface. For shops aiming to balance material removal and workpiece quality, the geometry yields tangible benefits in machining stability and part finish.

Versatile application and handling advantages in production

The insert’s designation and geometry support a wide range of turning tasks on materials classified in ISO groups M and S (rostfreie Stähle and heat‑resistant superalloys/titanium). The insert’s compact design and standardised interface simplify toolholder selection and change‑over. When paired with appropriate cutting data, this indexable solution enhances productivity through longer cutting intervals and reduced unplanned downtime, while offering straightforward handling and stock management for production planners.
