LNHU130630R-L55T WKP35G milling insert — 0° negative rake for steel and cast iron, Walter Tools

A LNHU130630R-L55T WKP35G milling insert engineered for high-process stability in machining of steel (P) and cast iron (K), suitable for demanding roughing and semi-finishing operations.

• Tiger‑tec Gold coated carbide grade WKP35G
• 0° negative rake for stable rough machining
• Rectangular insert with 3 mm corner radius
• Chipbreaker L55T for controlled chip formation

Higher process stability for productive roughing

The combination of the Tiger‑tec Gold coating and the WKP35G grade delivers a balanced performance that emphasises process stability and repeatable results when machining steel and cast iron. The insert’s negative rake at 0° reduces the tendency to dig in during heavy cuts, which translates into fewer interruptions and more consistent cycle times. Coated carbide provides a protective barrier against abrasive wear, so tool life is extended while surface integrity of the workpiece is preserved.

Safer machining through controlled chip formation

Equipped with the L55T chipbreaker and a 3 mm corner radius, the geometry promotes chip control that prevents long, entangling swarf and reduces the risk of re-cutting. Controlled chips improve throughput by lowering the need for secondary cleaning and minimising down-time caused by clogged tools or toolholders. For workshops prioritising uninterrupted production, the insert’s chip control contributes directly to operational efficiency.

Cost-effective durability and consistent performance

The coated carbide construction and the Tiger‑tec Gold technology are designed to offer reliable wear resistance under the thermal and mechanical loads typical for steel and cast-iron machining. This results in a longer effective cutting life and fewer insert changes over a production run, supporting better overall tool cost management. The product is produced to tolerance class H, ensuring dimensional consistency for repeatable tool set-ups and predictable machining results.

Practical integration and application guidance

The rectangular form and specification LNHU130630R-L55T make the insert straightforward to integrate into existing tool holders designed for this geometry. The grade is optimised for material groups P (steel) and K (cast iron) in accordance with ISO 513 principles — an explanation that helps planning of cut data: P grades are tuned for the heat and chip behaviour of steels, while K grades cope with the abrasive nature and brittle chips of cast iron. For specific cutting data and holder compatibility, refer to Metav Werkzeuge’s application support or catalogue resources.

FAQ

What materials is this insert suitable for?
The LNHU130630R-L55T WKP35G is specified for machining steel (P) and cast iron (K), benefiting from the Tiger‑tec Gold coating and WKP35G carbide grade.

How does the 0° negative rake affect cutting performance?
A 0° negative rake increases stability under heavy cuts, making the insert particularly suited to robust roughing operations where edge strength and reliable chip breaking are priorities.

What is the purpose of the L55T chipbreaker?
The L55T chipbreaker is designed to produce short, controllable chips and to reduce the risk of swarf entanglement, improving process security and reducing machine downtime.

Can this insert be used for finishing passes?
While optimised for roughing and semi-finishing, the insert can be employed for lighter passes if the tool geometry and cutting parameters are adjusted; consult Metav Werkzeuge for recommended cutting data.

What does the WKP35G grade offer compared with other grades?
WKP35G is a Walter Tools grade within the Tiger‑tec Gold family that balances wear resistance and edge robustness for a wide range of steels and cast irons, supporting consistent performance across production runs.
