P2841S-5N-E57 WKP25S Boring/Counterboring indexable insert (Tiger·tec Silver) – Walter Tools

The P2841S-5N-E57 WKP25S is a coated indexable insert designed for precise boring and counterboring in steel and cast iron, combining a wear-resistant Tiger·tec Silver surface with a controlled 5N‑E57 chipformer for predictable machining.

• Tiger·tec Silver coating for high wear resistance
• WKP25S coated carbide grade for stable cutting
• Optimised 5N-E57 chipformer for reliable chips
• Suited for machining steel and cast iron

Boosted productivity through a wear-resistant coating

The Tiger·tec Silver surface treatment delivers improved wear resistance under the thermal and mechanical loads typical of steel machining. Combined with the WKP25S cutting grade, the insert sustains cutting edge integrity for longer intervals, reducing the frequency of tool changes and supporting a smoother production flow. This translates into measurable gains in uptime and lower per-part tooling cost when used in systematic boring cycles.

Predictable chip formation for safer, faster cycles

The integrated 5N‑E57 chipformer is engineered to produce short, controllable chips when working in both unalloyed and alloyed steels as well as cast iron. Predictable chip behaviour simplifies chip evacuation and reduces the risk of surface damage or rework, supporting higher cutting speeds and more aggressive feeds where process reliability is critical. The result is consistent component quality and fewer interruptions for manual chip clearing.

Versatile use on steel and cast iron materials

Designed according to ISO material groups P and K, this insert is suitable for a wide range of applications in steel and cast iron. The coated carbide construction balances toughness and hardness to resist abrasive wear from cast materials while coping with the heat and deformation typical of steel cutting. For workshops processing mixed batches, the insert offers a practical compromise between performance and flexibility.

Ease of integration and stable results in production

The geometry and coating make the insert a pragmatic choice for standard boring toolholders and multi‑station boring heads, enabling straightforward integration into existing tooling systems. Its repeatable performance helps to maintain surface finish quality and dimensional consistency across production runs, supporting quality assurance targets and reducing downstream inspection effort.
