P2840S-1N-E67 WKP35S Drilling/Boring Indexable Insert – Tiger·tec Silver, for Steel and Cast Iron (Walter Tools)

P2840S-1N-E67 WKP35S is a drilling and boring indexable insert designed for productive metalcutting in steel and cast iron applications, utilising the Tiger·tec Silver coating technology for enhanced tool life.

• Tiger·tec Silver coating technology
• WKP35S coated carbide grade
• Optimised chipbreaker 1N-E67

High-performance coating and grade for longer productive life

The combination of the Tiger·tec Silver coating and the WKP35S carbide composition offers improved thermal resistance and a robust cutting edge, translating into prolonged tool life and fewer insert changes. This coated grade is engineered for the specific heat generation and chip behaviour encountered when machining steel (P); the coating reduces adhesive wear and maintains edge stability at elevated cutting temperatures. The result is measurable production gains: fewer interruptions for insert replacement and steadier component quality across batches. The insert’s build supports high metal removal rates while maintaining surface integrity.

Precise chip control and suitability for cast components

Equipped with the chipbreaker 1N-E67, the insert shapes and breaks chips reliably during drilling and boring, which reduces the risk of chip entanglement and improves process security in automated or semi-automated setups. The geometry is tuned to handle the abrasive tendencies and short, breaking chips typical of cast iron (K) as well as long, continuous chips in certain steels. The insert’s form allows predictable chip flow and easier evacuation from the hole or bore, helping maintain cycle times and toolpath consistency. An indexable insert of this type simplifies tool management in production environments that require rapid insert indexing and repeatable performance.

Application confidence, supply and process support

Manufactured under the Walter Tools portfolio, this insert benefits from established quality control and application know-how, making it a reliable choice for series production and job-shop environments alike. Compatibility with common drilling and boring holders ensures straightforward integration into existing toolsets. The technical characteristics of the grade and coating support cost-efficient machining through extended tool life and reduced scrap risk, contributing to lower overall process costs and improved output predictability. For customers seeking tailored cutting parameters, Metav Werkzeuge’s consultants can provide recommended feeds and speeds for specific alloy and bore conditions.
