P4840C-1R-F57 WKP35S – Drilling/boring indexable insert for steel and cast iron, Walter Tools

The P4840C-1R-F57 WKP35S is a drilling/boring indexable insert engineered for high-productivity holemaking and bore enlargement in steel and cast iron, combining a Tiger·tec Silver coating with a dedicated chipbreaker geometry.

• Tiger·tec Silver coated carbide grade
• Optimised for steel and cast iron machining
• Stable chip formation with 1R-F57 geometry
• Reliable cutting edge for series production

Higher productivity through advanced coating and grade

The combination of the Tiger·tec Silver coating and the WKP35S coated carbide grade provides measurable gains in cutting performance when machining steels (ISO group P) and cast irons (ISO group K). The coating reduces abrasive wear and improves thermal resistance, which permits higher cutting speeds and longer tool life compared with conventional grades. For production environments, this translates into fewer tool changes and a more consistent manufacturing rhythm, contributing directly to improved throughput and lower unit costs per hole.

Consistent chip control and improved surface quality

The 1R-F57 chipbreaker geometry is designed for controlled chip formation during drilling and bore finishing operations. Stable chips reduce the risk of entanglement and machine stoppages, while consistent shear action helps achieve a better surface finish and dimensional repeatability. In practical terms, the geometry supports reliable chip evacuation in through-hole and partial-depth applications, so operators benefit from reduced rework and a more predictable process window.

Designed for process reliability and easy implementation

As an insert for drilling and bore enlargement, the design supports quick indexing and replacement, keeping machine uptime high. The grade’s balance of toughness and wear resistance delivers robust edge stability under the thermal and mechanical loads typical of holemaking in steel and cast iron. Integrating this insert into a production line provides a dependable solution for serial drilling tasks, where repeatable results and minimal adjustment time are priorities. For application-specific cutting data or toolholder compatibility, consultation with Metav Werkzeuge can clarify speeds, feeds and coolant strategy.
