P4841P-8R-F57 WKP35S drilling/boring indexable insert for steel and cast iron — Walter Tools

The P4841P-8R-F57 WKP35S is an indexable cutting insert engineered for drilling and boring operations, optimised for demanding production environments handling steel and cast iron

• Tiger·tec Silver coating for wear resistance
• WKP35S grade for steel and cast iron
• Chipbreaker 8R-F57 for stable chip control
• Optimised geometry for process reliability

High-performance grade and coating for heavy-duty work

The insert combines the Tiger·tec Silver coating with the WKP35S hardmetal grade to deliver enhanced wear resistance and heat protection during continuous machining. The designation P / K indicates suitability for both P (steel) and K (cast iron) material groups as defined by ISO 513; this means the grade balances toughness for ductile materials and abrasion resistance for brittle, abrasive cast irons. The coating reduces flank and crater wear under elevated temperatures, extending effective tool life while maintaining dimensional stability in serial drilling and boring tasks.

Geometry and chip control that stabilise the process

The integrated chipbreaker 8R-F57 is designed to promote predictable breakage and evacuation of chips in interrupted and continuous cuts, improving surface quality and reducing the risk of recutting. By guiding chips away from the cutting edge, the geometry supports consistent cutting forces and reduces the likelihood of workpiece damage. For users less familiar with chipbreaker terminology: a dedicated chipbreaker interrupts long swarf into short, controllable segments, which in turn helps to maintain coolant access and prevents tool clogging—important factors in achieving repeatable component tolerances.

Productivity and process reliability for production environments

Equipped with a robust grade and tailored geometry, this indexable insert supports higher material removal rates and longer edge life, contributing directly to improved productivity and lower tool consumption in the production cycle. The stability offered by the combination of grade and chip control delivers predictable performance across batch runs, reducing downtime for tool changes and inspection. For facilities aiming to optimise machining workflows, the insert is a practical choice where consistent hole quality and economical tool life are required.
