P2841S-4N-E67 WKP35S — Drilling/Boring indexable insert (Tiger·tec Silver) by Walter Tools

P2841S-4N-E67 WKP35S is an indexable insert designed for drilling and boring applications, engineered for productive machining of steel and cast iron with a specialised chipbreaker geometry for reliable chip formation.

• Tiger·tec Silver coated grade WKP35S
• Optimised for steel and cast iron machining
• Chipbreaker geometry 4N‑E67 for stable chips
• Coated carbide for high process reliability

Maximise machining throughput with consistent wear resistance

The graded Tiger·tec Silver coating combined with the WKP35S carbide provides a robust balance of hardness and toughness that extends tool life under typical drilling and boring loads. This combination contributes to stable flank wear and predictable edge performance, which reduces the frequency of insert changes and unscheduled downtime. As a result, production cycles benefit from improved productivity and repeatable component tolerances. The insert’s coating technology controls thermal and abrasive wear mechanisms common in steel and cast iron machining, translating material behaviour into dependable tool performance.

Reliable chip control and secure cutting action for safe cycles

A defining advantage is the chipbreaker 4N‑E67, engineered to manage chip shape and evacuation during deep or interrupted cuts. Controlled chip formation minimises recutting and reduces the risk of tool breakage, helping to maintain machine availability and operator safety. In practical terms, the geometry promotes short, manageable chips when working with both steel and cast iron, reducing the need for manual chip clearing and lowering the chance of surface defects. This predictable chip behaviour supports automated setups and increases confidence in unattended or lights-out production runs.

Broad applicability across steel and cast iron operations

The insert’s specification shows suitability for P and K workpiece groups, meaning it is tailored for a range of unalloyed and alloyed steel grades as well as various cast iron types. Such versatility allows consolidation of tool inventories where one insert can cover multiple component families, simplifying tool logistics and reducing storage complexity. The graded, coated carbide substrate withstands the abrasive tendencies of cast iron while retaining edge integrity for the heat and strain typical of steel machining, enabling consistent surface finish and dimensional control.

Process security and integration into productive tool systems

Designed as part of a proven product line, this indexable insert supports repeatable results when paired with matching cutter bodies and clamping systems from the same tool family. The combination of coating, grade and chipbreaker architecture enhances process security by delivering a steady cutting response across varied feed and speed settings. For production engineering, this means easier parameter selection and reduced trial periods when ramping up new programmes. Documentation and proven application data for similar geometries further shorten qualification times in serial manufacturing.
