P4840P-7R-E57 WSP45G drill/reaming indexable insert — Tiger·tec Gold, 7R‑E57 chipbreaker (Walter Tools)

The P4840P-7R-E57 WSP45G is a drill/reaming indexable insert engineered for high-performance metalcutting applications, offering robust edge stability and designed for machining steel, stainless steel and heat-resistant superalloys.

• Tiger·tec Gold coated grade WSP45G
• 7R‑E57 chipbreaker for controlled chip formation
• Suitable for steel, stainless steel and superalloys
• Stable cutting edge under elevated temperatures

Improved productivity through coating and grade synergy

The Tiger·tec Gold technology paired with the WSP45G grade ensures a balance of toughness and wear resistance that promotes longer tool life and fewer index changes. Designed for demanding milling-style cutting conditions adapted to drilling and reaming inserts, this coating system reduces flank wear and supports stable cutting forces. The result is measurable productivity gains: fewer interruptions for tool changes and improved process reliability when working with challenging materials such as prehardened steels or heat-resistant alloys. The emphasis on consistent wear behaviour translates into reliable cycle times and predictable maintenance intervals.

Reliable chip control for safer machining

The 7R‑E57 chipbreaker geometry has been developed to manage chip formation in through-hole and reaming operations, reducing the risk of chip jamming and improving evacuation. By promoting segmented and controllable chips, the insert helps maintain coolant flow and avoids excess heat build-up at the cutting zone. This focused chip management improves surface finish and reduces the likelihood of rework, an economic advantage in batch production and high-value components. The chipbreaker design is particularly beneficial when machining ductile stainless steels and heat-resistant superalloys, where continuous chips are otherwise common.

Versatile material capability and application clarity

With the material designation P / M / S, the insert covers a wide range of substrates: standard and alloyed steels (P), stainless steels (M) and heat-resistant superalloys and titanium (S). The combination of substrate adaptability and coating performance makes the insert a versatile choice for shops that process mixed material families without frequent tool swaps. For users less familiar with industrial material groups, this means one insert can often replace several specialised grades, simplifying inventory while maintaining machining quality.

Process stability and repeatable results with a trusted brand

Produced by Walter Tools, the insert benefits from proven carbide grades and modern PVD coating techniques that are designed for repeatable edge life and stable cutting behaviour. This technical reliability supports consistent component tolerances and surface integrity across production runs. The design objective is not only wear resistance but also controlled fracture behaviour at the cutting edge, which reduces unexpected tool failures and contributes to safer, more predictable machining.
