P4841C-4R-E57 WKP35S indexable drill/reaming insert — Tiger‑tec Silver coating, for steel and cast iron | Walter Tools

The P4841C-4R-E57 WKP35S is an indexable drill/reaming insert designed for high demands in drilling and bore-finishing operations on steel and cast iron.

• Tiger‑tec Silver coating for long tool life
• WKP35S: coated carbide for reliable wear resistance
• Optimised 4R‑E57 chipbreaker for consistent chips
• Suited for machining steel and cast iron

Improved productivity through stable cutting performance

The Tiger‑tec Silver series combines a modern coating system with a robust carbide substrate to increase tool life and maintain cutting-edge stability. The WKP35S grade is engineered for the thermal and abrasive conditions typical of machining steel and cast iron, which reduces flank wear and keeps bore tolerances stable over longer tool intervals. By choosing this insert, production planners can expect fewer tool changes and more predictable cycle times, supporting continuous throughput and lower per-part manufacturing cost.

Predictable chip control and surface quality

An optimised 4R‑E57 chipbreaker geometry provides reliable chip control in interrupted and continuous drilling. The chip form is directed away from the cutting zone, decreasing re-cutting and improving thermal conditions at the cutting edge. For operators less familiar with insert geometries: the chipbreaker shapes the chips to prevent long, entangling swarf and to reduce the risk of surface damage. This results in consistent bore finishes and simplifies downstream cleaning, delivering measurable quality improvements with minimal process adjustment.

Application guidance and handling benefits

The insert is supplied in a standard indexable format that eases replacement and ensures consistent seating in compatible drill bodies. The coated indexable insert offers high process security during serial production and is particularly suitable where repeatability matters. For shops that process mixed batches of unalloyed and alloyed steels or grey and ductile irons, the WKP35S grade provides the versatility to handle varying workpiece conditions without frequent grade swaps. Simple handling and predictable wear behaviour also support planning for tool inventory and regrinding cycles.

FAQ

What materials is this insert optimised for?
The insert is optimised for machining steel and cast iron (ISO groups P and K) thanks to the WKP35S coated carbide grade and the Tiger‑tec Silver technology.

How does the 4R‑E57 chipbreaker improve machining?
The 4R‑E57 chipbreaker shapes and breaks chips to reduce re-cutting and improve evacuation, which enhances surface finish and stabilises tool life during drilling and reaming.

Is this insert suitable for high-speed conditions?
The Tiger‑tec Silver coating and coated carbide substrate support elevated cutting performance; suitability for specific cutting speeds depends on machine capability and workpiece alloying—trial cuts are recommended to determine optimal parameters.

Can the insert be used in indexable drill holders from other manufacturers?
The insert follows standard indexable geometries; compatibility depends on the holder specification. Verify seat and clamp compatibility for the P4841C-4R-E57 geometry before use.

How does the WKP35S grade compare to uncoated carbide?
The WKP35S coated grade offers superior wear resistance and thermal stability compared with uncoated carbide, providing longer tool life and more consistent process results in mixed steel and cast-iron applications.
