LNHU160708R-L55T WKP35S milling insert (rectangle, 16 mm) – Walter Tools, Tiger‑tec Silver

The LNHU160708R-L55T WKP35S is a rectangular milling insert engineered for efficient machining of steel (P) and cast iron (K), featuring a dedicated chipbreaker and a negative 0° relief for robust cutting.

• Tiger‑tec Silver coated grade WKP35S
• Optimised chipbreaker L55T for stability
• Rectangle form, 16 mm for versatile milling
• 0.8 mm corner radius for consistent edge life

Longer tool life through a proven grade

The Tiger‑tec Silver coating and the WKP35S grade combine to deliver enhanced wear resistance and stable edge behaviour when machining demanding materials. Designed as a coated carbide solution, this grade balances toughness and hardness to reduce flank and crater wear in continuous and interrupted milling. For production environments where process repeatability matters, the coated grade reduces the frequency of tool changes and contributes to steady component quality across long batches.

Predictable chip control and cutting mechanics

The insert’s L55T chipbreaker and 0° (negative) relief are intended to promote controlled chip formation and to protect the cutting edge during heavy or interrupted cuts. A 0.8 mm corner radius supports durable edges and improved surface finish while minimising edge chipping in roughing passes. The rectangular geometry and 16 mm nominal size enable stable clamping in standard milling cutters, which helps maintain concentricity and reduces vibration for more consistent machining results.

Practical selection and application guidance

This indexable insert is specified for the ISO groups P (steel) and K (cast iron), making it suitable for a wide range of general milling tasks from semi‑finishing to more aggressive roughing where edge strength is required. The tolerance class H indicates manufacturing accuracy suitable for standard industrial applications. For specific cutting speeds and feeds, pairing the grade with coolant strategies and appropriate tool-holding will maximise productivity and workpiece quality. For assistance on selection or to confirm suitability for a particular machine or workpiece, Metav Werkzeuge’s consultants can advise on matching the insert to the cutter body and machining conditions.

FAQ

Which materials can be machined with this insert?
The LNHU160708R-L55T WKP35S insert from Walter Tools is formulated for ISO material groups P and K, i.e. steels and cast iron, providing a balance of wear resistance and edge stability for these materials.

What benefit does the 0.8 mm corner radius provide?
A 0.8 mm corner radius increases the insert’s edge strength and improves surface finish compared with very small radii, reducing the risk of premature chipping during heavier milling operations.

How does the L55T chipbreaker influence performance?
The L55T chipbreaker promotes controlled chip formation and evacuation, which improves process stability and reduces the likelihood of entangling chips or inconsistent chip loads on the cutter.

What does a 0° (negative) relief mean in practice?
A negative 0° relief produces a robust cutting geometry with a stronger cutting edge, making the insert well suited to interrupted cuts and applications where edge security is a priority.

Is this insert suitable for both finishing and roughing operations?
Yes. The grade and geometry offer a compromise between toughness and wear resistance that suits semi‑finishing and roughing, provided the cutter body and clamping system are compatible with a rectangular 16 mm insert.
