P4840P-7R-A57 WSP45G Drilling/Counterbore Indexable Insert – Tiger·tec Gold by Walter Tools

The P4840P-7R-A57 WSP45G is an indexable insert engineered for drilling and bore‑enlarging operations, optimised for demanding applications in steel, stainless steel and high‑temperature alloys.

• Tiger·tec Gold coating, WSP45G grade
• For steel, stainless steel and superalloys
• Robust, stable cutting edge for high heat
• Optimised chip formation for productive machining

High productivity through coating and grade technology

The combination of Tiger·tec Gold technology and the WSP45G grade delivers a PVD‑coated cemented carbide solution that prioritises process reliability and extended tool life. The applied coating increases heat resistance and reduces wear, which directly translates into fewer tool changes and more uninterrupted production time. For production environments where cycle times and component repeatability matter, this insert supports stable cutting conditions and consistent surface quality, reducing downstream rework and improving overall machining throughput.

Confident machining across key material groups

Designed for the ISO groups P / M / S, the insert handles unalloyed and alloyed steel, stainless steel and demanding materials such as superalloys and titanium. The material suitability means the grade copes with typical issues such as heat build‑up, work hardening and difficult chip forms. The integrated chipbreaker 7R‑A57 promotes controlled chip segmentation, lowering the risk of built‑up edge and ensuring reliable evacuation during drilling and bore‑widening operations. This results in stable cutting forces and a predictable tool life in mixed‑material production runs.

Geometry and edge stability for consistent results

The insert geometry is adapted to drilling and counterboring tasks, offering a stable cutting edge that resists flank wear and chipping under thermal and mechanical stress. That stability, combined with targeted chip control, makes the component particularly suitable where productivity and surface finish are priorities. The robust design supports higher feed rates and contributes to productive machining by reducing stoppages for tool inspection and replacement. For applications that demand repeatable diameters and tight tolerances, the insert’s configuration helps maintain process windows over longer tool lives.

Application guidance and economic benefits

Using a coated, grade‑optimised indexable insert can lower unit costs by extending effective cutting time and reducing scrap from inconsistent finishes. The technology behind this insert focuses on practical benefits: improved wear resistance, enhanced heat tolerance and reliable chip control. These attributes make it a pragmatic choice for shops seeking to balance cutting performance with operational economy, particularly in small‑batch production where material mixes change frequently and process stability is paramount.
