P4841P-5R-A57 WKP35S indexable insert for drilling/boring, suitable for steel and cast iron — Walter Tools

The P4841P-5R-A57 WKP35S is an indexable insert engineered for drilling and boring tasks, optimised to deliver consistent chip control and wear resistance when machining steel and cast iron.

• Tiger·tec Silver coating for durability
• Coated carbide grade WKP35S
• Chipbreaker 5R-A57 for stable chips
• Optimised for steel (P) and cast iron (K)

Maximise throughput with a durable coated grade

The Tiger·tec Silver series combines a modern coating technology with a hard-wearing substrate to deliver sustained cutting performance under typical steel and cast iron conditions. The WKP35S grade is a coated carbide specifically tuned to resist abrasive wear and maintain a sharp cutting edge over prolonged cycles. For manufacturing environments where cycle time and tool-change frequency are critical, this insert supports a measurable increase in uptime and reduces unscheduled interruptions, leading to a more economical machining process.

Reliable chip control for safer, cleaner operations

The integrated 5R-A57 chipbreaker geometry steers chip formation toward short, controllable fragments when machining both unalloyed and alloyed steel as well as cast iron. Stable chips minimise the risk of workpiece and tool damage and facilitate unattended or batch machining. Explaining the geometry briefly: the chipbreaker guides coolant and shear flow at the cutting edge, reducing the formation of long, stringy chips and improving surface finish without compromising material removal rate.

Clear advantages in process security and surface quality

By combining a tailored grade and proven coating, the insert improves process security—fewer edge failures, predictable wear patterns and a consistent surface result across runs. The coated surface reduces built-up edge and adhesion on the insert flank, which translates into more consistent part quality and fewer rework cycles. For production planners, that predictability is an operational asset: cycle times remain stable and inspection throughput improves.

Application guidance and material compatibility

Designed for the ISO material groups P (steel) and K (cast iron), the insert is suitable for a broad spectrum of turning and boring operations where robust wear resistance and reliable chip breakage are required. When selecting machining parameters, consider the grade's strengths: moderate to high cutting speeds and feeds that match the workpiece hardness and machine rigidity will yield the best compromise between tool life and productivity. For specialised materials or unorthodox setups, a cutting test under representative conditions is recommended to confirm optimal parameters.

FAQ

Is this insert suitable for stainless steel applications?
No. The P4841P-5R-A57 WKP35S insert is specified for ISO groups P (steel) and K (cast iron) and is not listed for stainless steel machining.

Which chipbreaker should be chosen for consistent short chips?
The 5R-A57 chipbreaker integrated with this grade is designed to produce short, controllable chips when machining steel and cast iron, improving process safety and surface finish.

What benefits does the Tiger·tec Silver coating provide?
The Tiger·tec Silver coating on the WKP35S grade enhances wear resistance and reduces built-up edge, extending tool life and supporting more consistent cutting performance on steels and cast irons.

Can the insert be used for high-speed machining?
The combination of coated carbide and Tiger·tec Silver technology supports elevated cutting speeds compared with uncoated grades; final speed recommendations depend on machine rigidity and the specific steel or cast iron grade.

How does WKP35S compare to other grades for cast iron?
WKP35S is engineered to tolerate the abrasive nature and breaking-chip behaviour of cast iron, offering improved edge stability and predictable wear compared with general-purpose grades not tailored to cast iron.
