P4130-4R12-E47 WKP30S drilling/boring indexable insert by Walter Tools — Tiger·tec Silver, for Stahl and Gusseisen

The P4130-4R12-E47 WKP30S is a drilling/boring indexable insert designed for high-performance material removal in tough production environments, optimised for machining Stahl and Gusseisen.

• Tiger·tec Silver coated carbide grade
• Optimised for Stahl and Gusseisen
• Stable chip formation for constant results
• High process security and edge stability

Reliable removal and reduced downtime through advanced grade technology

The insert’s WKP30S grade, paired with the Tiger·tec Silver coating, delivers a balanced combination of wear resistance and toughness that supports longer tool life and fewer index changes. For industrial workshops seeking steady throughput, the coated carbide substrate provides resistance to abrasive wear common when machining Gusseisen while maintaining edge integrity during interrupted cuts in Stahl. The geometry code 4R12‑E47 indicates a chipbreaker form tuned to controlled chip separation, which reduces the risk of built-up edge and contributes to predictable tool life.

Consistent chip control for improved surface quality and process reliability

Controlled chip formation is central to repeatable results; the insert’s chipbreaker design promotes short, manageable chips that clear reliably from the bore. This translates into a more consistent surface finish and reduced cycle interruptions. In practice, the chip control reduces thermal load at the cutting edge and minimises vibration, which benefits dimensional stability on parts where bore tolerance and surface integrity matter. The coated surface also assists in friction reduction, supporting cleaner shear and improved finish on both Stahl and Gusseisen components.

Practical benefits for production planning and toolset standardisation

Adopting this insert in a toolholder system brings measurable benefits: fewer tool changes, predictable regrinding intervals and simplified inventory through a robust grade suitable across common materials. The insert’s compatibility with standard drilling and boring toolholders simplifies retrofitting into existing tool sets. For process engineers, this means easier optimisation of cutting parameters and a clearer cost-per-part calculation owing to consistent wear behaviour. The combination of robust edge stability and optimised chip control helps maintain throughput and reduces scrap rates in serial production.
