CCMT09T304-E47 WSM20S Bohr-/Aufbohrwendeschneidplatte — Walter Tools, Tiger·tec Silver for stainless steel and superalloys

A CCMT09T304-E47 WSM20S indexable insert engineered to ensure stable cutting performance when machining stainless steel and heat‑resistant superalloys in demanding turning operations

• Tiger·tec Silver coated carbide grade WSM20S
• Suitable for stainless steel and superalloys
• Rhombic 80° insert with 0.4 mm corner radius
• 7° clearance angle for stable chip control

Reliable performance for stainless steel and superalloys

The Tiger·tec Silver grade WSM20S is designed specifically for difficult‑to‑machine materials such as stainless steel (ISO group M) and heat‑resistant alloys (ISO group S). With a coated carbide substrate and a focus on edge stability, this grade reduces the tendency to form built‑up edge and copes better with the elevated cutting temperatures typical of these alloys. The result is more consistent surface finish and extended tool life compared with uncoated or general‑purpose grades. This makes the insert suitable where reproducible results and reduced downtime are priorities.

Geometry and coating that improve process stability

The Rhombic 80° form combined with a 0.4 mm corner radius and 7° clearance provides an effective balance between strength and cutting precision. The chipbreaker E47 is tuned to promote reliable chip formation under interrupted or continuous cuts, lowering the risk of chip entanglement and workpiece damage. The T3 thickness enhances seat stability in the tool holder, which translates into reduced vibration and improved repeatability. These geometric choices support higher productivity by allowing mid‑range feeds and speeds with secure edge life.

Practical benefits for workshop efficiency

Adopting this insert supports predictable machining cycles: the WSM20S coating technology improves thermal resistance, while the insert geometry delivers controlled chip evacuation and stable cutting forces. For production environments this translates into fewer tool changes, fewer scrap parts and a lower total cost of machining per component. Where setup variety exists, the insert’s universal rhombic angle and robust grade simplify inventory needs by covering multiple applications in stainless steel and superalloy machining. For advice on cutting data or holder compatibility, our technical consultants can provide tailored recommendations.

Notes on application and handling

When orienting the insert in the cutter body, ensure correct seating and clamping torque to preserve the specified 0.4 mm corner integrity and to maintain the intended chipbreaker function. For highest reliability, verify coolant strategy and monitor temperatures during trial cuts — the coating and grade are optimised for thermal loads, but stability benefits are maximised with suitable cutting conditions. If uncertain which geometry or grade matches a specific alloy and process, request a quick cutting test plan from Metav Werkzeuge to determine optimal parameters.
