P2840S-1N-A57 WKP35S drilling/boring indexable insert — Tiger‑tec Silver, for steel and cast iron — Walter Tools

The P2840S-1N-A57 WKP35S is a coated carbide indexable insert engineered for drilling and bore‑enlargement applications, offering enhanced wear resistance and controlled chip formation in steel and cast iron machining.

• Tiger‑tec Silver coating for enhanced wear resistance
• WKP35S grade optimised for steel and cast iron machining
• 1N‑A57 chipbreaker for controlled chip formation
• Consistent edge stability for productive drilling operations

Extended tool life through advanced coating technology

The combination of the Tiger‑tec Silver coating and a coated carbide substrate provides measurable benefits in terms of wear resistance and thermal stability. Coating technology reduces flank and crater wear during interrupted cuts and high temperatures common in steel machining, which translates directly into longer insert life and fewer tool changes. For production environments seeking predictable tool consumption, this performance characteristic supports higher machine utilisation and lower process costs without compromising component quality.

Reliable chip control and improved process security

The integrated 1N‑A57 chipbreaker is designed to produce short, consistent chips when machining ISO group P (steel) and K (cast iron). Controlled chip formation reduces the risk of chip entanglement, aids coolant flow around the cutting zone and improves surface integrity of the bore. As part of the WKP35S grade, the geometry and coating work together to maintain a stable cutting edge, resulting in consistent hole quality and repeatable cycle times — a clear advantage in batch and serial production.

Designed for productive drilling and bore‑enlargement cycles

The indexable design facilitates quick insert replacement and repeatable positioning, which supports uninterrupted production. The grade’s balance between toughness and hardness enables it to withstand the heat and mechanical stress typical of drilling operations in steel and cast iron, while the coating mitigates abrasive wear. The net effect is improved process reliability: fewer unplanned interruptions, better surface finish of the bore, and a more favourable total cost of ownership through reduced consumable turnover.

Practical selection and application guidance

The designation P2840S‑1N‑A57 WKP35S identifies the insert geometry, chipbreaker and material grade; matching the insert to the correct drill or boring head is essential for optimal results. When choosing an insert, consider the workpiece material, cutting parameters and machine rigidity — the WKP35S grade is tailored for operations where a balance of wear resistance and edge stability is required. For specialised alloys or atypical cutting conditions, consult technical documentation or Metav Werkzeuge’s advisors to align geometry and parameters with the intended machining task.
