TNMU160516R-G27 WKP35G – Triangle 60° milling insert by Walter Tools

The TNMU160516R-G27 WKP35G is a negative‑rake milling insert designed for reliable machining of steel and cast iron in general industrial milling applications.

• Triangle 60° geometry for versatile milling
• Tiger·tec Gold coating for long tool life
• 0° negative rake for stable cutting
• Suitable for steel and cast iron

Increased process reliability for high‑volume milling

The coated carbide grade WKP35G, part of the Tiger·tec Gold series, is engineered to resist abrasive wear and maintain a stable cutting edge over extended cycles. This results in fewer tool changes and more predictable production runs. The combination of coating and substrate ensures consistent performance under the thermal and mechanical loads typical when machining steel and cast iron.

Robust edge design for stable chip control

With a 1.6 mm corner radius and a dedicated chipbreaker G27, the insert delivers dependable chip formation and reduced edge chipping in interrupted cuts. The robust edge geometry supports both roughing tasks and productive semi‑finish passes, improving surface consistency while reducing the risk of operator intervention.

Geometry and rake tuned for heavy cutting

The triangular 60° format provides multiple indexable edges, improving economy per insert, while the 0° negative rake increases edge strength for heavy engagement and tougher cutting conditions. The insert’s form is optimised to withstand radial loads, making it suitable for stable slotting and face milling operations where rigidity and edge life are decisive.

Material versatility and ISO‑based application

Rated for ISO groups P and K, the insert is specifically suited to unalloyed and alloyed steel as well as cast iron. The WKP35G grade balances toughness and wear resistance, adapting to the heat generation and chip behaviour typical of these materials. This makes the insert a practical choice for mixed‑batch production where material changes are frequent.

Practical advantages on the shop floor

Tolerance class M and an industry‑standard indexable geometry mean easy replacement and predictable runout in typical toolholders. The insert’s size and form enable quick stocking and fast tool setup, supporting lean production processes. Fewer reworks and predictable tool life contribute directly to lower machining costs per component.

Application notes for process planners

The insert is intended for conventional milling strategies that benefit from a stable cutting edge and reliable chip evacuation. When combined with the right cutter body and cutting parameters for steel and cast iron, the result is an efficient, repeatable process with improved uptime and part quality.

FAQ

What materials is this insert best suited for?
The TNMU160516R-G27 WKP35G insert is designed for machining steel (ISO P) and cast iron (ISO K), exploiting the WKP35G grade for balanced wear resistance and toughness.

How does the Tiger·tec Gold coating improve performance?
The Tiger·tec Gold coating on the WKP35G grade increases abrasion resistance and thermal stability, which extends the effective tool life of the insert under demanding milling conditions.

What benefit does the 0° negative rake provide?
A 0° negative rake enhances edge strength and stability during heavy cutting and interrupted cuts, reducing the likelihood of edge chipping on this milling insert.

How many cutting edges are available per insert?
The triangle 60° geometry provides multiple indexable edges, allowing economical reuse of the insert faces before replacement.

Is this insert suitable for interrupted milling and slotting?
Yes, the combination of the robust corner radius, chipbreaker G27 and negative rake makes the insert well suited to interrupted cuts and slotting operations.
