P2841S-6N-A57 WKP25S – Drilling/Reaming Indexable Insert, Tiger‑tec Silver, for Steel & Cast Iron | Walter Tools

The P2841S-6N-A57 WKP25S is a drilling and bore‑enlargement indexable insert engineered for productive removal of material in steel and cast iron operations, combining a coated carbide grade with an optimised chipformer for stable cutting conditions

• Tiger‑tec Silver coating for wear resistance
• Optimised 6N‑A57 chipformer for chip control
• Suited to ISO P (steel) and K (cast iron) machining

Improved throughput through consistent chip control and coating technology

The combination of the Tiger‑tec Silver technology and the WKP25S coated carbide grade delivers tangible improvements in cutting stability and reduced flank wear during drilling and bore‑enlargement operations. The 6N‑A57 chipformer is designed to shape and evacuate chips reliably under the thermal and mechanical loads typical for ISO P and K groups, which helps to maintain feed rates and reduce unplanned stoppages. By promoting predictable chip breakage and evacuation, the insert supports higher machine utilisation and contributes to lower manufacturing costs per hole.

Predictable tool life and surface quality for production environments

The coated carbide construction and series design offer an advantageous balance between wear resistance and edge toughness, which translates into more reproducible component surfaces and fewer rejected parts. With the WKP25S grade, abrasive wear from cast‑iron machining is managed while retaining the edge integrity needed for steel workpieces. This predictability in wear behaviour makes process planning simpler and reduces the frequency of changeovers, supporting continuous production and improved economic efficiency.

Easy specification and integration into tool families

The geometry and designation of the insert are structured to allow selection according to toolholder and application geometry; catalogue‑ and geometry‑dependent deployment ensures the right grade is matched to the task. The insert’s assigned code and chipformer identify its intended role clearly, making procurement and tool inventory management straightforward for workshop managers and production engineers. Documentation of grade, chipbreaker and series simplifies ordering and ensures reproducibility across batches.

Application guidance and practical advantages in use

For machining tasks that alternate between steel and cast iron, the coated grade offers broad applicability and reduced setup complexity compared with single‑purpose grades. The insert supports finishing and semi‑finishing drilling/reaming operations where consistent chip formation and edge stability are required. Selection of the correct tool geometry remains important; the P2841S‑type designation and 6N‑A57 chipformer indicate the intended application profile, enabling process engineers to align cutting data with material group recommendations for reliable results.

FAQ

Which materials is the insert suitable for?
The P2841S-6N-A57 WKP25S insert is optimised for ISO P (steel) and ISO K (cast iron) applications and is designed to handle the typical thermal and mechanical conditions of these material groups.

What benefit does the Tiger‑tec Silver series provide?
The Tiger‑tec Silver series, embodied in the WKP25S grade, offers a balance of wear resistance and edge toughness that supports longer tool life and consistent surface quality in drilling and bore‑enlargement tasks.

How does the 6N‑A57 chipformer affect machining?
The 6N‑A57 chipformer promotes controlled chip breakage and evacuation, reducing the risk of chip entanglement and helping to maintain steady feeds and speeds during production.

Is the insert intended for finishing or roughing operations?
The insert is suitable for both finishing and semi‑finishing drilling/reaming where stable chip formation and edge integrity are required; final application depends on toolholder geometry and process parameters.

How should the grade be selected for mixed production of steel and cast iron?
For mixed production, the WKP25S grade within the Tiger‑tec Silver family provides versatile performance across steel and cast‑iron tasks; match the insert geometry and cutting data to the specific hole size and machine capacity for best results.
