P2840S-7N-F57 WKP35S — Bohr-/Aufbohrwendeschneidplatte (Tiger‑tec Silver), Walter Tools

The P2840S-7N-F57 WKP35S is a coated carbide indexable insert designed for bore and reaming applications, optimised for ISO groups P and K in demanding turning and boring operations.

• Tiger‑tec Silver coated carbide grade
• Optimised chip control with 7N‑F57 breaker
• Suitable for steel (P) and cast iron (K)
• Walter Tools quality and process reliability

High-performance machining with proven grade technology

The Tiger‑tec Silver WKP35S grade combines a finely tuned coating and carbide substrate to deliver consistent cutting performance when machining steel and cast iron. The coated carbide construction resists abrasive wear and thermal softening, which results in extended tool life and fewer insert changes during production runs. For users seeking predictable cycle times and reduced downtime, the insert’s geometry and material pairing are engineered to manage the heat and mechanical loads typical of ISO P and K applications, so machining parameters can be stabilised more rapidly and with less variance between batches.

Precise chip formation and surface integrity

The integrated chipbreaker 7N‑F57 is designed to control fragmenting chips typical of both steels and cast irons, reducing the risk of entanglement and improving evacuation during internal and external boring. Controlled chip formation contributes directly to surface finish and dimensional stability; the combination of insert geometry and Tiger‑tec Silver coating supports a reliable cutting edge throughout its service life, enabling consistent part quality. Operators benefit from fewer interruptions for chip-clearing and a lower incidence of rework caused by chip-related surface defects.

Process efficiency and shop-floor integration

As a production-ready insert, the design emphasises straightforward tool management and predictable wear behaviour, which supports tighter production planning and cost calculations. The designation and grade are compatible with standard clamping systems and are usable across a range of insert holders appropriate for boring and reaming operations. Where cycle time and throughput matter, this insert helps to reduce tool-change frequency and stabilise machining parameters, contributing to overall shop-floor productivity and better machine utilisation rates.

Application suitability and handling notes

The insert is certified for the machining groups P (steel) and K (cast iron) according to ISO classifications, making it a versatile choice for job shops and series production alike. The coated carbide grade is particularly effective where a balance between wear resistance and toughness is required. While the insert is geared towards harder production conditions, selection of feeds, speeds and coolant strategy should follow machine and workpiece-specific trials to fully exploit the WKP35S benefits and to achieve the intended surface integrity and tool life.
