TNMU11T304R-G27 WKP25S Fräswendeschneidplatte by Walter Tools — Triangle 60°, Tiger·tec Silver

The TNMU11T304R-G27 WKP25S is a triangle‑shape milling insert designed for productive machining of steel and cast iron, combining a negative 0° relief with Tiger·tec Silver coating for robust wear resistance

• Tiger·tec Silver coated grade WKP25S
• For steel (P) and cast iron (K) machining
• Triangle 60° shape with 0.4 mm corner radius
• Negative 0° relief for stable cutting

Consistent chip control for efficient production

The Tiger·tec Silver coating paired with the WKP25S grade provides a balance between wear resistance and toughness that promotes stable cutting over long tool lives. Coated carbide grades handle the heat and abrasive conditions typical when machining unalloyed or alloyed steel and cast iron; this reduces flank wear and preserves cutting geometry for longer intervals. The G27 chipbreaker is engineered to guide and break chips predictably, which shortens downtime for chip clearing and minimises the risk of rework due to poor chip evacuation. This results in measurable productivity gains on batch and continuous operations.

Geometry that supports repeatable accuracy and surface quality

The triangle 60° configuration with a 0.4 mm corner radius delivers a secure seating and three cutting edges per insert, optimising tool usage and cost per edge. The negative 0° relief contributes to a robust cutting edge that resists chipping under interrupted cuts or heavy engagement, making the insert suitable for operations where edge security is prioritised. For customers focused on surface finish, the combination of geometry and coating promotes consistent surface quality by reducing vibration and maintaining a sharp cutting line for longer periods.

Clear material range and application guidance

This grade is intended for steels (designation P) and cast irons (designation K) according to ISO 513 classifications. Coated hardmetal construction gives the insert the abrasion resistance needed for cast iron and the thermal stability demanded by steel cutting. When planning an operation, select cutting data (speeds, feeds and depths of cut) in line with workpiece alloy and rigidity; the insert’s design supports medium to heavy-duty milling where process security and repeatable results are required. For atypical alloys or very high hardness ranges, consult the technical data sheet to confirm suitability.

Designed for shop-floor reliability and simple inventory management

With three usable edges per triangle insert and a standardised geometry, the insert helps to simplify tool scheduling and reduce the number of variants kept in stock. The coated carbide construction and the Tiger·tec Silver technology are intended to deliver consistent performance across series parts, lowering the frequency of unscheduled tool changes. For operations seeking predictable throughput and reduced tooling overhead, this insert offers a balance of productivity and operational reliability that supports efficient process planning.

FAQ

What materials is this insert suitable for? The insert is designed for machining steel (P) and cast iron (K) according to ISO classifications; the Tiger·tec Silver coating and WKP25S grade suit these material groups.

How does the triangle 60° geometry affect tool life? Triangle 60° geometry provides three indexable cutting edges per insert and a secure seat, which increases usable life per insert and supports repeatable edge positioning.

Is the insert appropriate for interrupted cuts? Yes. The negative 0° relief and robust coated carbide grade give the insert enhanced edge security for interrupted and heavy milling situations.

What benefit does the G27 chipbreaker provide? The G27 chipbreaker is engineered for controlled chip formation and evacuation, reducing the risk of long or tangled chips and supporting consistent surface quality.

Can this insert be used for finishing and roughing operations? The insert’s geometry and coating enable both stable roughing and fine finishing when cutting data and machine rigidity are adjusted to the task.
