P2841S-7N-E67 WKP35S drilling/bore-enlarging indexable insert – Tiger·tec Silver, for steel & cast iron (Walter Tools)

The P2841S-7N-E67 WKP35S is a drilling and bore-enlarging indexable insert engineered for productive machining of steel and cast iron components in industrial production environments.

• Tiger·tec Silver coating for long tool life
• WKP35S coated carbide grade
• Chipbreaker 7N-E67 for controlled chip formation
• Designed for steel and cast iron machining

Longer tool life through optimised coating and grade

The insert combines the Tiger·tec Silver coating with the WKP35S coated carbide grade to reduce abrasive and adhesive wear during interrupted and continuous drilling cycles. The surface treatment improves heat resistance and reduces flank wear, which translates into longer intervals between indexings and fewer tool changes. For production-focused workshops this means more uptime and a predictable wear pattern that supports process planning and consistent output.

Stable chip control for safer, faster cycles

A dedicated chipbreaker, the 7N‑E67 geometry, is specified to shape and control chips in both short-breaking and semi-continuous forms. This results in reliable evacuation from holes and bores, reduced risk of entanglement and fewer interruptions caused by poor chip behaviour. When machining both steel (ISO group P) and cast iron (ISO group K) the chip control reduces coolant pressure spikes and helps maintain component surface quality without complex process adjustments.

Practical use and compatibility with common materials

Designed as an indexable solution for drilling and bore-enlarging operations, the insert is suited for standard and high-productivity machining centres. The cutting grade and coating combination is balanced for a wide material range, focusing on steel and cast iron, which are the primary suitable materials for this geometry and grade. The term "coated carbide" here indicates a base carbide substrate with a multi-layer coating system optimised for thermal stability and wear resistance, explained in straightforward terms for production planners and purchasing managers.

Process reliability and productivity advantages

Choosing a branded solution from a recognised toolmaker supports repeatable results across batches and shifts. The insert’s construction and geometry prioritise wear resistance and operational process security, helping to reduce scrap rates and rework. For manufacturing environments with mixed-series production, the consistency of cutting behaviour offered by this grade simplifies tooling lists and streamlines inventory management while maintaining surface finish and dimensional stability.

FAQ

What materials is this insert intended for?
The insert is specified for steel (ISO group P) and cast iron (ISO group K); the grade WKP35S is optimised for those material families.

How does the Tiger·tec Silver coating improve performance?
The Tiger·tec Silver coating increases thermal resistance and reduces flank and crater wear on the WKP35S grade, extending cutting life and stabilising cutting forces.

Is the chipbreaker suitable for deep-hole drilling?
The 7N‑E67 chipbreaker is designed for controlled chip formation and reliable evacuation, which supports deeper bore operations when combined with appropriate coolant and evacuation strategies.

Can this insert be used for stainless or other exotic alloys?
The data supplied specifies suitability for steel and cast iron; compatibility with stainless or high-alloy materials is not stated and should be verified with cutting data for those specific alloys.

Who manufactures the insert and what can be expected from the brand?
Walter Tools supplies this grade and geometry; the product is manufactured to the brand’s industrial standards for dimensional accuracy and repeatable cutting performance.
