P4160-2R08-E47 WSM20S Bohr-/Aufbohrwendeschneidplatte — Tiger·tec Silver, for rostfreier Stahl and superalloys (Walter Tools)

P4160-2R08-E47 WSM20S is an indexable drill/boring insert engineered for heavy machining of heat‑resistant alloys and rostfreier Stahl, offering thermal stability and controlled chip formation.

• Tiger·tec Silver coating for thermal stability
• Optimised chipbreaker 2R08-E47 for secure chip flow
• Suited to rostfreier Stahl and superalloys
• Coated carbide grade WSM20S for long tool life

Proven thermal resistance for difficult-to-machine materials

The combination of the Tiger·tec Silver coating and the WSM20S cutting grade provides enhanced heat resistance and improved wear behaviour when machining materials that retain heat. Materials in group S (heat‑resistant superalloys and titanium) and group M (rostfreier Stahl) challenge the cutting edge through poor thermal conductivity and adhesive wear; the coated carbide substrate offers a protective layer that reduces edge degradation and supports stable cutting performance under elevated temperatures. This stability translates into more predictable component quality and fewer unplanned tool changes, supporting continuous production workflows.

Secure chip control and consistent surface quality

The 2R08‑E47 chipbreaker geometry is designed to shape chips reliably across a range of feed rates, reducing risk of entanglement and improving surface consistency. Controlled chip formation helps maintain a steady cutting force, leading to repeatable surface finishes and reduced cycle-time variation. For job shops and production lines where reproducibility matters, this results in higher first-pass yields and lower downstream rework. The geometric optimisation also aids chip evacuation in deep or interrupted cuts, minimising the likelihood of built-up edge and prolonging the usable life of the cutting edge.

Productivity and integration benefits for the workshop

As an indexable insert, this solution supports cost-effective tool management: simple replacement of the insert restores cutting performance without regrinding the entire tool body. The coated carbide construction promotes longer tool life and consistent edge geometry over multiple indexings, which contributes to lower tooling costs per finished part. The insert is applicable where process security and surface integrity are priorities—typical sectors include aerospace, power generation and specialised stainless fabrication—offering machine shops a balance of productivity and machining reliability. For adaptation to specific machines or operations, consult machining parameters aligned with the coating and chipbreaker characteristics to maximise performance.
