P4840P-5R-E57 WKP35S drilling/boring indexable insert for steel and cast iron — Walter Tools

The P4840P-5R-E57 WKP35S is a Tiger·tec Silver indexable insert engineered for drilling and boring operations, optimised for machining steel and cast iron according to ISO material group designations.

• Tiger·tec Silver coating for enhanced wear resistance
• Optimised for steel and cast iron machining
• Geometry 5R‑E57 promotes reliable chip control
• Walter Tools quality for reproducible performance

Reliable chip control for uninterrupted production

The insert combines the 5R‑E57 geometry with the WKP35S grade to deliver consistent chip control, reducing the risk of clogging and unplanned downtime. The shaped chipbreaker and cutting-edge geometry are designed to generate predictable, short chips when machining cast iron and controlled, continuous chips in various steel grades. This behaviour simplifies chip evacuation in deep holes and long bores, enabling smoother cycle times and fewer manual interventions while maintaining cutting-edge integrity.

Robust coating and grade for extended tool life

The Tiger·tec Silver coating on a coated carbide substrate provides enhanced resistance to abrasive wear and thermal loads commonly encountered in steel machining. The WKP35S grade is formulated for balanced performance: it maintains edge stability under intermittent cuts and offers improved flank wear behaviour during continuous operations. As a result, the insert supports longer tool life and more predictable regrinding or replacement intervals, which contributes directly to reduced tooling costs and higher process reliability.

Application suitability and measurable advantages

Designed specifically for drilling and reaming-style operations, this insert is suitable for material groups P and K, meaning steel (unalloyed and alloyed) and cast iron workpieces. The combination of grade and geometry delivers superior surface finish and dimensional stability in bore-making tasks where tolerance and repeatability matter. The insert’s properties support higher machining speeds and feed rates in many setups, leading to measurable productivity gains and improved cost-efficiency per component produced.

Practical use and integration into your workflow

Integration into standard Walter Tools toolholders and drilling systems is straightforward; the insert’s ISO-style designation simplifies selection and stocking. When paired with appropriate holder rigidity and a matching cutting parameter set, the insert provides reproducible results across batches and operators. For production environments seeking consistent output, the insert helps to maintain part quality while lowering the frequency of tool changes and unplanned stoppages, supporting continuous high-throughput machining.
