Bohr-/Aufbohrwendeschneidplatte P2840S-5N-A57 WKP25S — Tiger‑tec Silver for steel & cast iron | Walter Tools

P2840S-5N-A57 WKP25S is a high-performance boring and enlarging indexable insert, designed for productive metalcutting in steel and cast iron applications

• Tiger‑tec Silver coating for increased wear resistance
• WKP25S grade – coated carbide performance
• Optimised chipformer 5N‑A57 for stable machining
• Suited for steel and cast iron applications

Reliable performance where material variability matters

The Tiger‑tec Silver series combines a modern coating system with a robust carbide substrate to ensure consistent tool life and productive cutting across a wide range of workpiece grades. The WKP25S grade is formulated to handle the thermal and mechanical demands typical of ISO group P (steel) while also coping with the abrasive nature of ISO group K (cast iron). This balance reduces unexpected downtime and supports predictable cycle times on lathe and boring operations.

Longer tool life through advanced coating technology

The Tiger‑tec Silver coating provides a hard, wear‑resistant surface that reduces flank and crater wear during continuous and intermittent cuts. Coated carbide inserts of this type allow for higher cutting speeds and improved edge stability, which translates into fewer tool changes and lower overall machining costs. The term coated carbide refers to a cemented carbide substrate with a multi‑layer coating applied to improve adhesion, hardness and heat resistance.

Better chip control for safer, faster machining

The integrated chipformer 5N‑A57 geometry is optimised for predictable chip breaking and evacuation when enlarging holes or boring shafts. Stable chip formation minimises the risk of re‑cutting and surface damage, supporting superior surface finish and dimensional accuracy. In practical terms, improved chip control contributes directly to higher throughput and fewer process interruptions, particularly when processing tougher steel grades or fragmenting cast iron chips.

Practical guidance and process assurance for industrial use

For workshops and production environments seeking process security and repeatable results, the insert’s combination of geometry and grade supports consistent machining parameters. Technical documentation and cutting data are available to help select appropriate speeds, feeds and depths of cut for specific materials. If additional clarification is required on integration or toolholder compatibility, Metav Werkzeuge offers expert consultation to align the insert with existing tooling systems and machining cycles.

FAQ

What materials is this insert suitable for?
The P2840S-5N-A57 WKP25S insert is suitable for ISO groups P and K, specifically steel and cast iron, providing balanced performance across both material types.

What does the WKP25S designation mean?
WKP25S is the Walter Tools grade within the Tiger‑tec Silver family; it denotes a coated carbide formulation optimised for wear resistance and stable cutting in typical steel and cast iron applications.

How does the 5N‑A57 chipformer benefit machining?
The 5N‑A57 chipformer promotes predictable chip breaking and evacuation, reducing re‑cutting and improving surface finish during boring and hole enlargement.

Can the insert be used at higher cutting speeds?
Thanks to the Tiger‑tec Silver coating and coated carbide substrate, the insert supports increased cutting speeds compared with uncoated grades, subject to correct cooling and cutting parameters.

Is this insert compatible with standard boring toolholders?
The geometry and designation P2840S-5N-A57 WKP25S describe a standardised indexable insert format; compatibility depends on the toolholder design—consult the cutting data or Metav Werkzeuge for confirmation.
