TNMU160508R-G27 WKP25S milling indexable insert — triangle 60°, Tiger‑tec Silver, Walter Tools

The TNMU160508R-G27 WKP25S is a coated carbide milling insert designed for productive machining of steel and cast iron in versatile milling setups

• Tiger‑tec Silver coating for long life
• Optimised for steel and cast iron
• Triangle 60° geometry for versatile use
• Negative 0° rake for secure machining

High-performance grade for consistent removal rates

The insert uses the WKP25S cutting grade within the Tiger‑tec Silver family, a coated carbide solution engineered for stable chip formation and extended tool life under typical steel and cast iron conditions. The combination of coating and substrate promotes thermal resilience and wear resistance, which reduces the need for frequent index changes and supports predictable tool-change intervals. For production environments seeking to increase uptime, this material pairing ensures a reliable balance between cutting-edge hardness and toughness, delivering consistent machining performance across batch and flow production.

Geometry and chip control that improve surface quality

Designed in a triangle 60° form with a corner radius of 0.8 mm, this insert offers a robust cutting edge suitable for a wide range of slotting and shoulder milling operations. The G27 chipbreaker is tailored to the typical chip types encountered when machining P (steel) and K (cast iron) groups according to ISO 513, promoting controlled, short chips and minimising re-cutting. The negative 0° rake gives the insert a secure cutting geometry that stabilises the tool–workpiece interface, helping to maintain surface finish and reduce vibration in interrupted cuts. These geometric choices translate directly into measurable benefits: fewer rejects, steadier spindle loads and a more uniform workpiece finish.

Practical advantages for workshop integration and supply

Selection of this insert simplifies tooling logistics: the standardised format and tolerance class M mean predictable clamping and repeatable positioning across common toolholders. The product is suitable for medium to high cutting speeds where coated carbide benefits are required; the attribute set supports both roughing and semi-finishing when used within recommended parameter windows. For purchasing and technical evaluation, Metav Werkzeuge provides application support and delivery coordination to integrate the insert into existing tool systems, ensuring the transition from specification to shop-floor use is efficient and documented.

FAQ

What materials is this insert suitable for?
The TNMU160508R-G27 WKP25S is specified for machining steel (P) and cast iron (K), leveraging the Tiger‑tec Silver coating and WKP25S grade for reliable performance.

How does the corner radius affect cutting?
A corner radius of 0.8 mm increases edge strength for heavier cuts while contributing to a stable surface finish when used with appropriate cutting parameters.

Is the chip control suitable for interrupted cuts?
Yes, the combination of the G27 chipbreaker and negative 0° rake provides controlled chip formation and improved stability in interrupted milling situations.

Can this insert be used for finishing passes?
The coated carbide grade and geometry allow for semi-finishing and finishing when cutting parameters are optimised for the material and machine rigidity.

Which series does the insert belong to and what does that mean?
This insert is part of the Tiger‑tec Silver series; the series designation indicates a modern coating technology intended to enhance wear resistance and process reliability.
