CNMQ160812-A57T WKP35S milling indexable insert by Walter Tools — Tiger·tec Silver coated, rhombic 80°

The CNMQ160812-A57T WKP35S is a rhombic 80° milling indexable insert engineered for robust machining of steel and cast iron in productive milling routines.

• Tiger·tec Silver coating for extended tool life
• Designed for steel (P) and cast iron (K)
• Rhombic 80° geometry for versatile milling

Durable coated grade for reliable productivity

The Tiger·tec Silver coating combined with the WKP35S carbide grade provides a balance of wear resistance and reliable cutting-edge stability. Designed for the typical thermal and chip formation conditions when machining steel and cast iron, this coated cemented carbide grade helps maintain cutting performance under continuous loads. The result is less frequent index changes and a reduced risk of unexpected edge failure, which supports smoother production sequences and predictable tool life.

Geometry that improves stability and surface finish

The rhombic 80° insert form with a 1.2 mm corner radius and a 0° (negative) free angle offers mechanical robustness at the cutting edge. This geometry promotes stable cutting forces and consistent contact conditions, which contributes to an improved surface finish and dimensional stability on workpieces. For applications where edge strength and repeatable results matter, the insert geometry reduces the tendency for edge chipping and supports a controlled chip flow under varying cutting parameters.

Proven process security and application relevance

Belonging to the Tiger·tec Silver series and specified in tolerance class M, the insert is intended for productive milling tasks that demand consistent results. The A57T chipbreaker and the WKP35S grade are tuned to handle the abrasive behaviour of cast irons and the heat-affected chips typical of steels, enabling stable chip formation and manageable machining conditions. This contributes directly to process reliability, lower scrap rates and predictable maintenance intervals for high-throughput operations.

Practical advantages on the shop floor

The insert’s combination of a modern coating system and a robust geometry reduces downtime associated with tool changes and rework. As a result, machining operations can benefit from higher productivity and an improved cost-per-part metric.

FAQ

What materials is the insert suitable for?
The CNMQ160812-A57T WKP35S insert is suitable for machining steel (P) and cast iron (K), with the WKP35S grade optimised for these workpiece groups.

What benefits does the Tiger·tec Silver coating provide?
The Tiger·tec Silver coating offers enhanced wear resistance and edge stability, helping the insert to deliver consistent cutting performance and longer indexable life under the thermal loads common when machining steel and cast iron.

How does the rhombic 80° form affect application versatility?
The rhombic 80° geometry provides a robust cutting edge and adaptable cutting angles, making the insert useful in a range of milling operations where a combination of strength and good surface quality is required.

Why is the 1.2 mm corner radius important for results?
A 1.2 mm corner radius increases edge strength and reduces the risk of chipping, supporting reliable surface finishes and dimensional stability during heavier cutting or interrupted cuts.
