P4841P-5R-A57 WKP25S – Drilling/boring indexable insert, Tiger·tec Silver (Walter Tools)

P4841P-5R-A57 WKP25S is a coated carbide drilling/boring indexable insert optimised for productive machining of steel and cast iron, offering stable cutting and reliable chip control.

• Tiger·tec Silver coating for extended tool life
• WKP25S grade for dependable performance
• 5R-A57 chipbreaker for controlled chips
• Coated carbide for high wear resistance

Reliable results in steel and cast-iron machining

The combination of WKP25S grade and Tiger·tec Silver technology provides a robust cutting edge tailored to the thermal and mechanical demands of ISO P and K materials. The insert’s coated carbide substrate balances toughness and wear resistance, which helps to maintain dimensional stability in drilling and boring cycles. This reliability reduces the frequency of tool changes and contributes directly to higher process uptime and repeatable part quality.

Better chip control and process stability

The chipbreaker 5R-A57 is engineered to form predictable, manageable chips during axial cutting, improving evacuation from the tool zone and lowering the risk of re-cutting. Controlled chip formation supports consistent surface finish and reduces secondary operations. For production environments where cycle time and scrap reduction are priorities, this geometry promotes safer, more productive runs while preserving the integrity of the cutting edge.

Practical handling and grade choice for varied tasks

The coated carbide construction and the WKP25S specification make this insert versatile across a range of steels and grey or nodular cast irons. The grade’s coating enhances thermal resistance and reduces abrasive wear, extending cutting life in continuous and semi-continuous operations. Selection of feeds and speeds will depend on machine rigidity and hole geometry; however, the design intent is clear—productive material removal with predictable tool performance and improved surface consistency.

FAQ

Which materials can be machined with this insert?
The P4841P-5R-A57 WKP25S insert is formulated for ISO P and K groups, that is steel and cast iron, and performs best where those substrate characteristics are present.

What does the WKP25S grade offer?
WKP25S is a Walter Tools grade offering a coated-carbide combination that emphasises wear resistance and edge stability for reliable performance in steel and cast-iron applications.

What advantages does the Tiger·tec Silver coating provide?
The Tiger·tec Silver coating increases thermal and abrasive wear resistance, which extends tool life and supports consistent cutting behaviour in demanding cycles.

How does the 5R-A57 chipbreaker influence machining?
The 5R-A57 geometry promotes controlled chip formation and evacuation, improving process stability and reducing the chance of re-cutting or chip-related interruptions.

Is this insert suitable for both finishing and heavy material removal?
The insert is designed for productive machining across a range of severities; actual suitability for finishing or heavy removal depends on tool geometry and cutting parameters.
