• Suitable for steel and cast iron machining
• Carbide grade WKP35S, coated hardmetal
• Chipbreaker 1R‑F57 for stable chip control

Greater productivity through advanced coating and material design

The Tiger·tec Silver coating and the WKP35S coated carbide grade combine to offer higher wear resistance and improved heat management during drilling cycles. This results in longer tool life and fewer tool changes, which directly reduces downtime and increases throughput on production lines. For engineers and workshop managers seeking measurable gains in output, the coated grade is tuned for the typical thermal and mechanical loads encountered when machining steel and cast iron, enabling consistent removal rates without premature flank or crater wear.

Reliable chip control and machining quality from optimised geometry

The 1R‑F57 chipbreaker geometry provides controlled chip formation and evacuation during boring operations, which lowers the risk of chip entanglement and workpiece damage. Stable chip control leads to predictable surface finish and dimensional consistency, especially important in serial production and precision assemblies. The insert’s geometry helps maintain a stable cutting edge, reducing the need for frequent rework and supporting tighter process windows for operators and CAM programmers focused on repeatable, high-quality results.

Application focus: targeted for steel and cast iron to ensure process security

Specifically manufactured for machining groups P (steel) and K (cast iron) according to ISO classification, the insert supports a broad range of unalloyed and alloyed steels as well as abrasive cast materials. The technical choice of a coated hardmetal grade means better resistance to abrasive wear on cast iron and improved toughness for interrupted cuts in steel. For production environments where process security and consistent cycle times matter, this solution minimises unexpected downtime and contributes to overall cost efficiency by extending useful tool life and improving repeatability.

FAQ

What materials can this insert machine effectively?
The insert is suitable for machining steel and cast iron as indicated by the P/K designation; the WKP35S grade is engineered for the thermal and abrasive conditions typical of these groups.

How does the Tiger·tec Silver coating benefit tooling performance?
The Tiger·tec Silver coating on the WKP35S grade reduces abrasive wear and improves heat resistance, which extends the service life of the insert and stabilises cutting conditions in drilling operations.

What role does the 1R‑F57 chipbreaker play in machining?
The 1R‑F57 chipbreaker geometry promotes controlled chip breaking and evacuation, lowering the risk of chip-related interruptions and improving surface finish and process repeatability during boring.

Is this insert suitable for interrupted cuts in steel?
Yes; the coated carbide WKP35S and the insert geometry are designed to handle interruptions commonly encountered when drilling or boring in steel, providing a balance between toughness and wear resistance.

Which product should be referenced when ordering or specifying as a replacement?
Reference the designation P4840P-1R-F57 WKP35S or the SKU P4840P-1R-F57-WKP35S-WALTER to ensure the correct coated carbide insert and geometry are supplied.
