P4841P-7R-A57 WKP25S — Indexable insert for drilling/boring, Tiger·tec Silver (Walter Tools)

A P4841P-7R-A57 WKP25S indexable insert designed for high‑productivity drilling and boring in Stahl and cast iron applications

• Tiger·tec Silver coating for high wear resistance
• WKP25S grade for Stahl and cast iron machining
• 7R‑A57 chipbreaker for controlled chip formation
• Walter Tools quality for stable production

Productive machining of Stahl and cast iron with Tiger·tec Silver

The insert is optimised for the machining groups P and K (P = Stahl, K = cast iron) and combines a coated carbide grade with a process‑oriented geometry. The Tiger·tec Silver technology emphasises wear resistance and thermal stability, which translates into consistent cutting-edge life under typical drilling and boring loads. For production environments, this means more predictable tool intervals and fewer interruptions caused by premature wear. The designation P4841P‑7R‑A57 WKP25S denotes the geometry and the grade; the catalogue‑dependent application range remains defined by component geometry and setup.

Consistent chip control and reduced rework thanks to the 7R‑A57 chipbreaker

The 7R‑A57 chipbreaker is developed to produce short, manageable chips when cutting Stahl and cast iron, reducing the risk of entanglement and improving surface finish. Controlled chip formation supports safer, faster cycle times and simplifies chip evacuation in through‑hole and blind‑hole operations. Combined with the insert’s coated substrate, the chip control reduces flank wear rates and contributes to predictable edge life, which helps maintain component tolerances and lowers the incidence of rework.

Practical selection and application guidance for workshop use

Selection depends on machine capability, hole geometry and cooling strategy; the WKP25S grade is a versatile choice where a balance of productivity and tool life is required. The indexable insert’s geometry suits continuous and interrupted cuts typical for drilling and boring, and the coating’s thermal behaviour supports elevated cutting speeds where machines and workholding permit.

FAQ

What materials is this insert suitable for?
The P4841P‑7R‑A57 WKP25S insert is specified for machining P and K groups, meaning it is suited to Stahl (P) and cast iron (K) applications.

How does the Tiger·tec Silver coating benefit tool life?
Tiger·tec Silver enhances thermal stability and wear resistance on the WKP25S grade, which helps sustain cutting performance and extend the usable edge life in drilling and boring operations.

When should the 7R‑A57 chipbreaker be chosen over other geometries?
Choose the 7R‑A57 chipbreaker when controlled, short chip formation is required—typical for through‑hole drilling or interrupted cuts in Stahl and cast iron where chip management and surface finish are priorities.

Is this insert suitable for high‑speed cutting?
The coated WKP25S grade with Tiger·tec Silver supports elevated cutting speeds where machine rigidity, clamping and cooling permit; select cutting data accordingly.

Can the P4841P‑7R‑A57 WKP25S be used for both blind and through holes?
Yes, the insert geometry and chipbreaker are designed to perform reliably in both blind and through‑hole drilling and boring, though parameters should be adapted to hole depth and evacuation conditions.
