P2840S-1N-A57 WKP25S drilling/boring indexable insert, Tiger·tec Silver coating — Walter Tools

P2840S-1N-A57 WKP25S is a coated indexable insert designed for drilling and boring operations in steel and cast iron, delivering stable cutting performance in demanding production environments

• Tiger·tec Silver coating for extended tool life
• Optimised chipformer 1N‑A57 for reliable chips
• Application: steel and cast iron (ISO groups P, K)
• Walter Tools grade WKP25S with stable cutting edge

High productivity through optimised coating and grade

The combination of the Tiger·tec Silver coating and the WKP25S carbide grade delivers a measurable increase in tool life and process stability during medium to high cutting loads. The coating technology reduces adhesive and abrasive wear, while the grade balances toughness and hardness to resist chipping on interrupted cuts. For production planners this means fewer index changes and more uptime, with consistent surface quality on both steel and cast iron workpieces.

Reliable chip control for safer machining

The insert’s 1N‑A57 chipformer is engineered to produce short, controllable chips in typical P and K materials, reducing the risk of entanglement and machine downtime. Improved chip control also supports stable coolant flow and more predictable tool forces, which helps maintain bore accuracy and repeatability during serial operations. The result is both improved cycle times and lower scrap rates in routine drilling and boring tasks.

Compatibility and process guidance for shop floors

This indexable insert is intended for use in standard drilling and boring toolholders compatible with the P2840S geometry. Its design supports reliable seating and clamping, ensuring a consistent cutting edge position that assists in maintaining dimensional tolerances. When paired with appropriate feeds and speeds for the material group, the insert enables efficient machining strategies for small to medium batch sizes, with benefits in both setup frequency and overall throughput.

Practical benefits for operators and process engineers

Beyond the raw cutting performance, the insert’s balanced carbide formulation and coating reduce the need for frequent inspections and regrinds, contributing to predictable tool budgets and less process variation. The product suits workshops aiming to standardise tooling across steel and cast iron applications, offering a straightforward route to improved productivity without complex parameter modifications.

FAQ

What materials is this insert intended for?
The P2840S-1N-A57 WKP25S insert is specified for machining steel and cast iron (ISO groups P and K), utilising the Tiger·tec Silver coating and WKP25S grade for those materials.

How does the 1N‑A57 chipformer affect machining?
The 1N‑A57 chipformer on this Walter Tools insert produces short, consistent chips suitable for drilling and boring, improving chip evacuation and reducing re-cutting risk.

Is the insert suitable for interrupted cuts or harder steels?
WKP25S provides a balance of toughness and wear resistance; while optimised for general P and K applications, tool life in interrupted or higher-alloy steels should be validated with adjusted cutting parameters.

Can the insert be re-sharpened or reground?
This coated carbide insert is designed as an indexable cutting element; typical practice is indexing or replacement rather than regrinding to retain coating benefits.

Which series does the insert belong to and what does that imply?
Belonging to the Tiger·tec Silver series means the insert benefits from advanced coating technology aimed at reducing adhesive and abrasive wear for more consistent performance in production.
