P4840C-4R-F57 WKP35S Drill/Boring indexable insert for steel and cast iron — Walter Tools, Tiger·tec Silver

P4840C-4R-F57 WKP35S is a coated carbide indexable insert engineered for high‑productivity drilling and boring in steel and cast iron, combining a Tiger·tec Silver coating with a geometry tuned for stable chip formation and repeatable performance

• Tiger·tec Silver coating for extended tool life
• Optimised 4R‑F57 chipbreaker for reliable chip control
• Designed for steel and cast iron machining
• WKP35S grade: coated carbide with robust edge life

High productivity through advanced coating and grade

The combination of Tiger·tec Silver and the WKP35S coated‑carbide grade delivers a significant increase in usable life for the cutting edge. The coating reduces friction and heat at the tool–workpiece interface, so the insert sustains higher cutting loads with less wear. This leads to longer intervals between indexings or replacements and contributes directly to improved throughput in serial drilling and boring operations.

Predictable chip control and surface quality

The 4R‑F57 chipbreaker was developed to produce short, controllable chips during holemaking in demanding materials. Consistent chip formation lowers the risk of workpiece damage and tool breakage and helps to maintain stable edge life across batches. As a result, process quality is more predictable and secondary operations for chip removal are reduced, supporting an uninterrupted production flow.

Process reliability with application‑oriented design

The insert geometry has been selected for rigidity and reliable seating in standard clamping systems, reducing vibration and run‑out effects in deep or blind holes. The design supports moderate climb and conventional milling orientations in drilling adaptions, which means that when paired with suitable holders and feeds, productivity and repeatability are enhanced. Maintenance intervals are simplified by predictable wear patterns.

Material guidance and practical use

This cutting grade is optimised for ISO groups P (steel) and K (cast iron), addressing the typical heat generation and abrasive wear characteristics of these materials. In practice, the insert is suitable for a range of steel grades and cast‑iron types where a coated carbide insert provides the best balance of tool life and surface finish. For mixed production runs the grade offers wide applicability and reliable performance in series production.

FAQ

What materials is this insert suitable for?
The P4840C‑4R‑F57 WKP35S insert is suitable for ISO group P (steel) and K (cast iron), offering a balanced performance for common steel grades and a variety of cast irons.

How does the 4R‑F57 chipbreaker affect machining?
The 4R‑F57 chipbreaker on the Walter Tools insert promotes short, controllable chips and reduces the likelihood of long stringy chips, which improves process security and surface quality during holemaking.

Is this insert compatible with standard drilling holders?
Yes. The insert is designed for conventional indexable insert drilling and boring systems; correct seating and appropriate clamping are essential for the promised performance of the P4840C‑4R‑F57 WKP35S plate.

Can the grade be used for mixed batches of steel and cast iron?
The WKP35S grade is formulated to handle both steel and cast iron within its application range, making it a practical choice for workshops handling mixed production.

What is the main benefit of Tiger·tec Silver coating on this insert?
Tiger·tec Silver reduces friction and thermal load, extending tool life and improving wear resistance under typical drilling and boring conditions encountered with steel and cast iron.
