P4840C-7R-F57 WSP45G drilling/boring indexable insert by Walter Tools — Tiger·tec Gold, 7R-F57

P4840C-7R-F57 WSP45G is an indexable insert designed for precision drilling and bore-enlargement applications across a wide range of demanding materials.

• Tiger·tec Gold PVD grade WSP45G for long life
• Chipbreaker 7R-F57 for consistent chip control
• Versatile for steel, stainless and superalloys
• Stable cutting edge for demanding bore work

Extended tool life through advanced coating and grade

The combination of the Tiger·tec Gold coating and the WSP45G grade delivers a robust, PVD‑coated carbide solution that resists wear under elevated temperatures common in drilling operations. This coating technology reduces flank wear and improves abrasive resistance, which translates into longer tool life and fewer tool changes on the shop floor. The result is a measurable improvement in uptime and a reduction in overall machining cost when processing challenging alloys.

Consistent chip formation and cutting stability

The dedicated chipbreaker 7R‑F57 is engineered to promote repeatable chip control during bore enlargement, preventing long stringy chips and supporting secure evacuation from the hole. Stable chip formation reduces the risk of re-cutting and tool damage, improving surface finish and dimensional stability. For interrupted cuts or deeper bores, this controlled chip behaviour supports higher process reliability and safer tool operation.

Broad material capability for mixed production runs

Specified for material groups P / M / S, this insert is suited to unalloyed and alloyed steel, stainless steel, and superalloys and titanium. The grade’s toughness helps to withstand the thermal and mechanical loads typical of stainless and heat‑resistant alloys, while preserving edge stability when cutting steels. For workshops that handle mixed batches, the grade’s versatility simplifies tooling inventory and supports consistent production quality across varied workpieces.

Practical advantages for production machining

As an indexable insert intended for drilling and bore tasks, the design emphasises reliable seating and repeatable geometry in the tool holder to maintain bore accuracy over multiple re‑indexes. The coated carbide construction minimises edge crumbling and supports continuous operation under moderate to heavy cutting conditions. For production environments seeking predictable tool life and consistent part quality, this insert presents a practical balance of toughness and wear resistance that improves process stability.
