Delivering consistent productivity with Tiger·tec Silver

The coated carbide grade from the Tiger·tec Silver series provides a balance between wear resistance and reliable chip control, which translates into longer tool life and fewer indexings. Designed for the typical heat generation and chip formation when machining steels and the abrasive nature of cast iron, the grade WKP35S offers improved process security. As a result, cycle times can be shortened and the cost per part is reduced thanks to lower insert consumption and predictable tool performance under continuous production.

Geometry and edge design that support stable cutting

The rhombic 80° geometry, combined with a 0° (negative) relief angle and a 1.2 mm corner radius, produces a robust cutting edge suited to a wide range of milling operations, from finishing to more heavy-duty passes. The negative clearance increases edge strength for intermittent cuts and interrupted surfaces, while the defined corner radius improves surface quality and supports consistent chip evacuation. These design choices mean fewer unexpected tool failures and a steadier surface finish on components, which is particularly valuable in batch production.

Application focus and process benefits for metalworking shops

Intended primarily for the machining of unalloyed and alloyed steel (ISO group P) and cast iron (ISO group K), this insert is a practical choice where material variability and abrasive conditions are common. The combination of a coated hardmetal substrate and the D57T chipbreaker geometry helps to maintain stable chip formation across a range of cutting parameters, enabling more reliable machining windows and easier parameter transfer between machines. For operations seeking reproducible results and reduced setup tuning, this insert supports consistent output and contributes to overall process efficiency.

FAQ

What materials is this insert suitable for?
The CNMU160812-D57T WKP35S is designed for machining steel (ISO group P) and cast iron (ISO group K), with the Tiger·tec Silver grade optimised for those material behaviours.

Which operations benefit most from the rhombic 80° geometry?
Rhombic 80° inserts are versatile for a range of milling tasks; the geometry of this insert supports both finishing passes and more robust milling where edge strength and access angles matter.

How does the Tiger·tec Silver coating improve performance?
Tiger·tec Silver enhances wear resistance and thermal stability, leading to longer tool life, better surface quality and more predictable chip control in steel and cast iron machining.

What does the 0° (negative) relief angle mean in practice?
A 0° negative relief increases the cutting edge strength and is advantageous for interrupted cuts or heavy engagement, helping to prevent edge chipping under demanding conditions.

What does tolerance class M indicate for this insert?
Tolerance class M denotes the dimensional tolerance level of the insert, ensuring consistent fit and repeatable seating in tool holders for reliable indexing and performance.
