P2841S-1N-E57 WKP25S drilling/bore indexable insert — Tiger·tec Silver for steel and cast iron by Walter Tools

The P2841S-1N-E57 WKP25S is an indexable insert engineered for drilling and bore-enlarging operations in steel and cast iron, combining a coated carbide grade with a dedicated chipbreaker for reliable production.

• Tiger·tec Silver coating for longer tool life
• WKP25S grade optimised for steel and cast iron
• Stable chip formation for consistent performance
• Designed for productive drilling and bore finishing

Greater tool life through advanced coating technology

The combination of the Tiger·tec Silver coating and a coated carbide substrate delivers better wear resistance and a longer edge life compared with uncoated grades. This results in fewer tool changes and lower machine downtime, which translates directly into improved productivity on repetitive drilling and bore-enlarging programmes. The coated surface also supports higher process reliability under the thermal and mechanical loads typical for machining steel and cast iron.

Reliable chip control for defined process behaviour

The chipbreaker 1N‑E57 is designed to produce short, controllable chips in both P and K material groups. For operations where consistent chip evacuation and stable cutting forces are essential, the geometry reduces the risk of clogging and enables steady feed rates. In practical terms this means improved surface finish and reproducible cycle times when machining components made from steel or cast iron, even in longer production runs.

Shop-ready geometry and clear economic benefits

With a dedicated geometry for drilling and bore finishing, this indexable insert keeps setup changes minimal and integrates easily into existing tool-holding systems. The WKP25S grade balances toughness and abrasion resistance, making the insert a cost‑effective choice for mixed production runs. The result is a measurable reduction in overall tooling costs and a smoother workflow for batch and continuous operations, backed by Walter Tools’ established manufacturing quality.

FAQ

What materials is this insert suitable for?
The insert is suitable for steel and cast iron machining; the WKP25S grade is optimised for P and K material groups.

What does Tiger·tec Silver bring to machining?
Tiger·tec Silver coating enhances wear resistance and edge stability, improving tool life in demanding drilling and bore operations.

Which chipbreaker is integrated and why does it matter?
The chipbreaker 1N‑E57 provides controlled, short chips to support process security and consistent surface finish in both steel and cast iron.

Is this insert compatible with standard drilling holders?
The insert uses a standard indexable insert form and is intended for common drilling/bore tool holders; verify holder geometry and clamping before assembly.

How does WKP25S balance toughness and abrasion resistance?
WKP25S is formulated to offer a compromise between toughness and abrasion resistance, enabling productive cutting in mixed-series production without frequent edge failures.
