P2841S-7N-A57 WKP25S drilling/boring indexable insert — Walter Tools, Tiger‑tec Silver, for Stahl and cast iron

P2841S-7N-A57 WKP25S is a drilling/boring indexable insert engineered for demanding metalcutting applications, offering a coated cemented carbide grade from Walter Tools' Tiger‑tec Silver family.

• Series Tiger-tec Silver coating
• WKP25S coated carbide grade
• Optimised for Stahl and cast iron
• Stable chip formation and wear resistance

Higher productivity thanks to advanced coating and grade

The combination of the Tiger‑tec Silver coating and WKP25S grade yields a balanced performance profile: improved heat resistance allows higher cutting speeds while the coated cemented carbide substrate maintains edge integrity. This results in measurable gains in productivity and a reduced need for frequent insert changes. The coating technology reduces built‑up edge and improves oxidation resistance, which is particularly beneficial in continuous drilling or bore enlargement operations where consistent cutting conditions are critical.

Reliable machining of Stahl and cast iron with controlled chip behaviour

Designed specifically for ISO groups P and K, the insert matches the thermal and mechanical demands of Stahl and cast iron workpieces. The geometry and chipbreaker designation (7N‑A57) promote chip control, reducing the risk of chip packing and improving process stability. For customers less familiar with chipbreaker nomenclature: the chipbreaker is the engineered surface geometry that shapes and breaks chips into manageable lengths, thereby protecting the workpiece and toolholder and facilitating unattended or automated cycles.

Consistent surface quality and reduced downtime through robust edge performance

Stable flaking behaviour and wear resistance from the coated substrate contribute to repeatable surface finishes and dimensional stability in production. The insert’s attributes support longer intervals between changeovers, lowering machine downtime and process variability. In series production, this consistency translates into higher first‑pass yield and fewer rework operations, strengthening overall cost efficiency without compromising precision.

Straightforward integration and economical operation in existing tooling systems

As an indexable insert, the component is intended for quick indexing and replacement in compatible drill or boring heads, delivering low per‑part tooling costs over time. The standard ISO designation and the clear grade identification simplify inventory management and substitute selection across operations. For efficient implementation, pairing the insert with suitable coolant strategy and stable clamping is recommended to exploit its full potential while maintaining toollife.
