P4840C-5R-E67 WKP35S Drill/boring indexable insert for steel and cast iron – Walter Tools

The P4840C-5R-E67 WKP35S is an indexable insert engineered for drilling and boring operations, optimised to deliver consistent performance when machining steel and cast iron.

• Tiger·tec Silver coating for wear resistance
• Optimised for machining steel and cast iron
• Coated carbide grade WKP35S for extended life
• Geometry 5R-E67 for controlled chip formation

Longer tool life through advanced coating and grade

The combination of Tiger·tec Silver coating and the WKP35S coated carbide grade provides noticeably improved wear resistance under the thermal and mechanical stresses typical of drilling and boring. The advanced coating reduces flank and crater wear, which extends tool life and reduces the frequency of changeovers. For production environments where uptime and predictable tool performance matter, this insert offers a cost‑effective route to more stable machining cycles and fewer unexpected interruptions.

Consistent chip control for safer, faster cycles

The 5R‑E67 chipbreaker geometry is designed to promote controlled chip formation and evacuation during axial cutting, reducing the risk of chip entanglement and surface damage. Improved chip control leads directly to higher process reliability and allows safely increased cutting parameters in many applications. In short production runs and longer batch work alike, predictable chip behaviour contributes to improved surface finish and reduced cycle times.

Broad material compatibility with clear application focus

Designed for the ISO groups P and K, the grade is tailored for demanding work in steel and cast iron. The cutting substrate and coating balance hardness and toughness to cope with the heat generated when machining steels, while also resisting the abrasive wear typical of cast iron. This focused material capability makes the insert suitable for mixed shops where both materials are processed and where one insert family can simplify tooling logistics.

Practical benefits for the workshop and the machining process

Using a dedicated drill/boring insert with a robust grade and defined chipbreaker helps to reduce setup variability and supports repeatable quality across batches. The insert geometry and coating technology together provide better edge stability and consistent cutting behaviour, which reduces rework and increases first‑pass yield. Where application data exist, matching coolant strategy and cutting parameters to the insert will further improve life and surface integrity.
