SCMT120408-E47 WSM20S Bohr-/Aufbohrwendeschneidplatte – Tiger·tec Silver, suitable for stainless steel machining, Walter Tools

The SCMT120408-E47 WSM20S is a square 90° indexable insert for boring and counterboring, engineered for secure chip formation and stable cutting when machining stainless steels and heat‑resistant alloys.

• Tiger·tec Silver coating for enhanced wear resistance
• WSM20S grade for stainless steel and superalloys
• 7° clearance angle and 0.8 mm corner radius
• Square 90° form, chipbreaker E47

Increase productive output with stable cutting and long tool life

The combination of the Tiger·tec Silver coating and the WSM20S coated carbide grade provides a tangible improvement in tool life and process stability. The advanced coating reduces flank wear and supports consistent cutting performance under thermally and mechanically demanding conditions, so less time is spent on tool changes and regrinding. For production environments where downtime directly affects throughput, this insert offers a reliable, repeatable cut that contributes to predictable cycle times and lower overall tooling costs.

Confident machining of stainless steels and heat‑resistant alloys

Designed for materials classified under ISO group M and S, the insert excels when facing the adhesion and heat‑related challenges of stainless steel and superalloys. The integrated E47 chipbreaker promotes reliable chip control, reducing the risk of built‑up edge and improving surface integrity. The 7° clearance angle helps to manage cutting forces and temperature at the cutting edge, resulting in a more consistent surface finish and reduced risk of workpiece deformation in thin or temperature‑sensitive components.

Precise geometry for easy integration and consistent results

The square 90° plate form with a 0.8 mm corner radius and designation SCMT120408‑E47 gives a predictable engagement for boring operations and straightforward indexability for multi‑edge use. The insert thickness and form factor suit standard toolholders and allow fast seat‑and‑index replacement, simplifying inventory management. Where operators or process planners require clarity, the insert’s geometry supports straightforward programming and setup, contributing to fewer start‑up iterations and a shorter path to production quality.
