P4840P-3R-A57 WKP35S Drill/boring indexable insert — Tiger·tec Silver for steel and cast iron | Walter Tools

P4840P-3R-A57 WKP35S is a drill/boring indexable insert engineered for demanding metalcutting tasks in steel and cast iron, optimising productivity in serial and mixed-batch production

• Tiger·tec Silver coating for enhanced wear resistance
• Optimised 3R‑A57 chipbreaker for consistent chips
• Designed for steel and cast iron machining
• Stable cutting edge for high productivity

Increase throughput with proven wear resistance

The combination of the Tiger·tec Silver coating and the WKP35S grade delivers reliable wear resistance, which reduces flank wear and extends the time between index changes. Coated carbide grades are selected for their ability to withstand the high temperatures and abrasion typical of machining steel and cast iron, so fewer tool changes are required and machine uptime is increased. The economic effect is clear: extended service intervals translate into lower unit costs per workpiece while maintaining dimensional stability.

Predictable chip control for safer, faster cycles

The integrated 3R‑A57 chipbreaker shapes and breaks chips consistently, improving evacuation from the hole and reducing the risk of tool chatter. Chipformers manage the material flow at the cutting edge so that short, controlled chips are produced during bore enlargement and drilling. This controlled behaviour enables higher feeds and stable cutting conditions, which in turn contribute to improved surface quality and repeatable cycle times in routine production.

Designed for mixed production environments

This indexable insert is tailored to operations that machine both steel and cast iron, where material-specific wear and chip behaviour demand a versatile grade. The insert geometry of P4840P‑3R‑A57 supports common drilling and boring toolholders and is suited to setups where flexibility and fast insert replacement are priorities. By using indexable inserts, stock removal remains economical, as only the cutting edge is renewed while the body of the holder is retained.

Practical handling and integration benefits

Selection and handling are straightforward: the insert is compatible with standard holders matching its designation and is supplied in a familiar ISO-type format. Because the cutting edge performance is designed for productive machining, process planners can expect stable cutting edge behaviour and good reproducibility when machining series components. For questions about optimised parameters or holder compatibility, the technical team at Metav Werkzeuge can advise on feeds and speeds tailored to the application.

FAQ

What materials is this insert suitable for?
The P4840P-3R-A57 WKP35S insert is specified for machining steel and cast iron, matching the P and K classifications and engineered to handle the typical heat and abrasion of those materials.

How does the Tiger·tec Silver coating benefit cutting performance?
The Tiger·tec Silver coating on the WKP35S grade reduces adhesive and abrasive wear, improving tool life and sustaining cutting performance over longer runs compared with uncoated grades.

What advantage does the 3R‑A57 chipbreaker provide?
The 3R‑A57 chipbreaker produces short, controlled chips that aid evacuation during drilling and boring, lowering the chance of entanglement and promoting stable cutting conditions.

Is this insert suitable for stainless steel?
Stainless steel suitability is not specified for this grade; the WKP35S insert is optimised for steel and cast iron, so machining stainless may require a different grade or coating strategy.

How is the insert integrated into existing tooling systems?
The insert follows the P4840P‑3R‑A57 designation and is compatible with matching drill and boring holders; using indexed inserts reduces tooling waste and simplifies edge replacement during production.
