Bohr-/Aufbohrwendeschneidplatte P4840P-8R-F57 WSP45G – Tiger‑tec Gold coated drilling/boring insert by Walter Tools

Bohr-/Aufbohrwendeschneidplatte P4840P-8R-F57 WSP45G offers a versatile, wear-resistant solution for drilling and enlarging operations across steel, stainless steel and high-temperature alloys

• Tiger‑tec Gold PVD-coated grade WSP45G
• Optimised 8R‑F57 chipbreaker geometry
• Suited for steel, stainless steel and superalloys
• Robust coated carbide for drilling and boring

Increased productivity through a resilient coating

The Tiger‑tec Gold PVD coating combined with the WSP45G grade provides a clear productivity advantage: enhanced wear resistance reduces edge breakdown and extends tool life under the thermal and mechanical loads typical of drilling operations. By choosing a coated carbide insert, process interruptions for index changes are less frequent, so cycle times shorten and tool change costs fall. The result is measurable uptime improvement and a steadier production flow, particularly in medium to high batch sizes.

Reliable chip control for safer machining

The 8R‑F57 chipbreaker geometry has been developed to control chip formation in interrupted cuts and confined drilling spaces. Stable chip evacuation minimises rework and spindle dwell, improving hole quality and reducing the risk of built-up edge on the cutting face. Where heat generation is significant—such as when machining stainless steel or superalloys—the combination of the chipbreaker and the coated cutting edge supports consistent process stability and predictable tool wear, which simplifies parameter selection for shopfloor engineers.

Broad material compatibility with focused performance

Designed for ISO groups P, M and S, this insert performs across steel, stainless steel and heat-resistant alloys, including titanium-based materials. The substrate and PVD system balance toughness and edge strength, so the insert resists chipping when cutting tough microstructures yet maintains a hard, wear-resistant surface for abrasion control. For production environments with mixed workpiece materials, the grade offers a reliable compromise between cutting-edge stability and abrasion resistance, supporting repeatable hole tolerances and improved precision.

Practical handling and application hints

The insert is supplied in the standard ISO geometry P4840P-8R-F57 and is intended for drilling and boring tool bodies that accept indexable cutting plates of this family. When setting up feeds and speeds, favour conservative depth-of-cut values during trial cuts to verify chip flow with the 8R‑F57 breaker; once established, modest increases in spindle speed are typically possible thanks to the thermal resilience of the coating. For quieter, more predictable machining, ensure coolant application and chip evacuation are aligned with the toolholder configuration to fully exploit the insert’s strengths.

FAQ

What materials can be machined with this insert?
The P4840P-8R-F57 WSP45G insert from Walter Tools is suitable for ISO groups P, M and S, meaning it can machine steel, stainless steel and heat-resistant superalloys including certain titanium alloys.

How does the 8R‑F57 chipbreaker affect machining?
The 8R‑F57 chipbreaker is engineered to produce short, controllable chips during drilling and enlarging operations, improving evacuation and reducing the likelihood of built-up edge when using the WSP45G grade.

Is this insert appropriate for high‑temperature alloys?
Yes, the combination of a robust substrate and the Tiger‑tec Gold coating gives the insert thermal and mechanical resistance suitable for many superalloys and demanding applications within the S group.

Which tool bodies accept this insert designation?
Toolholders and drilling systems that take ISO-format drilling/boring indexable plates in the P4840P family are compatible with the P4840P-8R-F57 geometry; verify holder seat and clamping codes before assembly.

How does the coating improve tool life compared with uncoated grades?
The PVD Tiger‑tec Gold layer reduces abrasive wear and stabilises the cutting edge under cyclic thermal loads, typically extending useful tool life and delivering more consistent hole dimensions over a series of components.
