P2840S-3N-A57 WKP25S – Drilling/boring indexable insert, Tiger·tec Silver, for steel and cast iron | Walter Tools

P2840S-3N-A57 WKP25S is an indexable insert for drilling and boring operations, designed to deliver stable cutting performance in mixed production environments where steel and cast iron are machined.

• Tiger·tec Silver coated carbide grade WKP25S
• Optimised 3N‑A57 chipbreaker for consistent chips
• For steel (P) and cast iron (K) applications
• Stable cutting edge for high productivity

Greater process reliability through advanced coating and grade

The combination of Tiger·tec Silver coating and the WKP25S carbide grade provides a balance of wear resistance and toughness that supports predictable tool life in serial machining. This coated carbide formulation reduces adhesive and abrasive wear, which leads to fewer unplanned tool changes and a steadier surface finish over long runs. Where process stability and repeatability matter, the insert’s engineered coating technology helps maintain dimensional accuracy and reduces the risk of premature edge failure, supporting continuous production.

Controlled chip formation for uninterrupted machining

The 3N‑A57 chipbreaker geometry is engineered for consistent chip breaking during drilling and boring, particularly when working with both short and stringy chips. By guiding chip flow away from the cutting zone, the chipbreaker reduces clogging and minimises the need for manual intervention, which improves cycle times and operator safety. In practice, improved chip control translates directly into fewer stoppages and more reliable machine utilisation across shift work.

Versatility across steel and cast iron applications

Designed and classified for ISO groups P (steel) and K (cast iron), this insert adapts to the differing demands of these materials: coping with the heat and chip formation typical of steel machining while resisting the abrasive wear often encountered with cast iron. The result is a single indexable solution that reduces tool inventory complexity and supports flexible production scheduling when batches include multiple material types.

Practical integration and predictable performance

The insert designation and geometry make it suitable for integration into standard drilling and boring tool assemblies where these indexable plates are specified. The engineered grade and chip control features mean the cutting edge remains robust under typical production feeds and speeds, offering predictable performance from batch production to continuous machining. Procurement channels through Metav Werkzeuge ensure availability and faster replacement cycles to keep spindles turning.

FAQ

What materials is this insert suitable for?
The P2840S-3N-A57 WKP25S insert is designed for ISO groups P (steel) and K (cast iron), offering wear resistance for abrasive castings and heat tolerance for steel machining.

How does the 3N‑A57 chipbreaker benefit drilling operations?
The 3N‑A57 chipbreaker improves chip control during drilling and boring, promoting consistent chips that clear the cutting zone and reducing the likelihood of chip-related interruptions.

What advantage does the Tiger·tec Silver coating provide?
Tiger·tec Silver coating on the WKP25S grade increases resistance to adhesive and abrasive wear, which extends cutting edge life and supports stable surface finishes in serial production.

Is this insert suitable for mixed-production environments?
Yes, the insert’s grade and chipbreaker are tailored for reliable performance when batches include both steel and cast iron components, lowering the need for multiple specialised inserts.

How does the insert support productivity in long production runs?
By combining a durable coating with a stable cutting edge geometry, the insert offers repeatable tool life and predictable wear, reducing downtime and tool-change frequency.
