P4841C-3R-E57 WKP35S — Drilling/Boring indexable insert for steel and cast iron — Walter Tools

The P4841C-3R-E57 WKP35S is a coated carbide indexable insert optimised for productive drilling and boring operations in a wide range of steels and cast irons

• Tiger·tec Silver coating for longer tool life
• WKP35S grade for steel and cast iron
• 3R‑E57 chipbreaker for stable chip control
• Suitable for productive drilling and boring

Faster cycle times through targeted material design

The Tiger·tec Silver coating, combined with the WKP35S coated carbide grade, is designed to reduce wear and maintain a stable cutting edge during continuous drilling operations. This results in fewer index changes and longer intervals between tool interventions, which directly improves productivity on medium- to high-volume machining tasks. The coating technology also aids thermal resistance, so the insert keeps its geometry better at elevated cutting temperatures.

Reliable chip control and process security

The 3R‑E57 chipbreaker geometry delivers consistent chip control for the characteristic chip forms encountered when machining steel and cast iron. Stable chip evacuation reduces risk of re-cutting and protects the hole surface finish, supporting repeatable results in series production. The chip management also contributes to safer setups by preventing chip accumulation in the tool path, which is especially beneficial during deep-hole drilling and when using higher feeds.

Practical advantages for workshop planning

Using this insert in a standard drilling or boring tool body permits predictable tool-life assessments thanks to the combination of coating and substrate. The coated carbide substrate provides a balance between toughness and wear resistance, enabling economical operation across diverse component batches. For planners, this means simplified inventory management: one grade covers multiple steel and cast-iron applications without frequent tool changes.

How the insert improves component quality

Through its geometry and coating, the insert supports improved dimensional consistency and surface integrity of machined holes. Better heat control and reduced abrasive wear help to avoid premature tool edge breakdown, which in turn preserves bore tolerance and reduces scrap rates. The overall effect is a measurable improvement in process capability for medium-duty drilling and boring tasks.
