P2840S-7N-A57 WKP35S – Bohr-/Aufbohrwendeschneidplatte, Tiger‑tec Silver coated carbide (Walter Tools)

The P2840S-7N-A57 WKP35S is an indexable drill/boring insert engineered for productive machining of steel and cast iron, combining a robust chip control geometry with the Tiger‑tec Silver coating system for extended tool performance.

• Tiger‑tec Silver coating for increased wear resistance
• WKP35S grade for steel and cast iron machining
• 7N‑A57 chipbreaker for controlled chip formation
• Compatible with standard boring toolholders

Boosted productivity through wear-resistant coating and consistent edge life

The Tiger‑tec Silver series brings a coated cemented carbide substrate that is designed to resist abrasive wear and maintain a stable cutting edge over longer cycles. This stability reduces unplanned tool changes and supports higher material removal rates in repetitive production environments. For machining tasks that require consistent surface finish and repeatability, the coated grade delivers measurable benefits in process reliability and cost per component. The combination of coating technology and grade provides a balance between toughness and hardness appropriate for mixed operation in both steel and cast iron.

Predictable chip control for safer, faster boring cycles

The integrated 7N‑A57 chipbreaker is optimised to produce short, controlled chips when machining abrasive or brittle materials, lowering the risk of long, entangling swarf and improving evacuation from deep bores. Controlled chip formation reduces interruption of feed and spindle motion, which in turn minimises surface marks and tool vibration. In practical terms, this geometry helps maintain steady cutting forces and supports higher feed rates without sacrificing component quality, making it suitable for serial production where process stability is a priority.

Compatibility and application guidance for straightforward integration

This indexable solution is specified for the ISO material groups P (steel) and K (cast iron), indicating its suitability across a broad range of unalloyed and alloyed steels as well as grey and nodular cast iron grades. The insert fits common boring and drilling toolholders that accept the P2840S-7N-A57 form factor, permitting fast replacement and re-indexing during maintenance. For operators unfamiliar with ISO group designations: P refers to steels (designed for their thermal and chip-formation characteristics) and K to cast iron (optimised for abrasive wear and short, breaking chips), which explains why this grade is chosen for mixed-shop environments.

FAQ

What materials is this insert designed to machine?
The P2840S-7N-A57 WKP35S insert is specified for steel (ISO group P) and cast iron (ISO group K), making it suitable for a wide range of unalloyed and alloyed steels and common cast irons.

How does the Tiger‑tec Silver coating benefit machining?
Tiger‑tec Silver coating on this WKP35S grade increases wear resistance and supports longer tool life under abrasive conditions, improving process reliability in serial production.

What is the role of the 7N‑A57 chipbreaker?
The 7N‑A57 geometry provides controlled, short-chip formation that aids swarf evacuation and reduces the risk of chip entanglement in deep boring and drilling operations.

Is the insert compatible with standard toolholders?
The insert matches the P2840S-7N-A57 form factor and is intended for common boring and drilling holders that accept this insert shape, enabling straightforward integration and fast replacement.

Can this insert be used for high-speed cutting?
The WKP35S grade and Tiger‑tec Silver system are optimised for process security and wear resistance; suitability for high-speed cutting depends on machine capability and cutting parameters—consult Metav Werkzeuge for recommended settings.
