P4841P-3R-A57 WKP25S — Drilling/boring indexable insert for steel & cast iron by Walter Tools

P4841P-3R-A57 WKP25S is a coated carbide indexable insert from the Tiger·tec Silver family, designed for drilling and boring operations where consistent chip formation and long tool life are essential in steel and cast iron applications.

• Tiger·tec Silver coated carbide WKP25S
• Optimised chip control for steel and cast iron
• Robust edge for stable high-productivity cuts
• Compatible with P4841P-3R-A57 tool geometries

Extended tool life through modern coating technology

The Tiger·tec Silver coating combined with the WKP25S grade provides a balance of wear resistance and toughness that translates into longer tool life under typical drilling and boring loads. Coated carbide is engineered to withstand the thermal and abrasive stresses common when machining ISO P (steel) and ISO K (cast iron) workpiece groups, reducing frequency of insert changes and improving process uptime. The result is a measurable improvement in productivity in batch and continuous production environments.

Predictable chip formation and surface finish

The 3R‑A57 chipbreaker geometry is engineered for controlled chip segmentation and evacuation when cutting steels and cast irons. Consistent chip control reduces clogging and the risk of secondary damage, which helps maintain a stable cutting edge and reduces rework. This geometry supports reliable surface quality and repeatable hole accuracy in drilling and boring cycles, leading to fewer interruptions and a smoother machining process overall.

Practical compatibility and production readiness

Designed for use in standard drilling and boring toolholders that accept the P4841P geometry, this indexable insert integrates easily into existing toolsets and replacement cycles. The coated carbide construction suits a broad range of steels and cast irons, making it a versatile choice for general-purpose and demanding applications alike. For precise tool selection or adaptation to specific machine parameters, technical documentation is available and Metav Werkzeuge’s consultants can provide targeted guidance.
