LNGX130720R-L55 WKP35G milling indexable insert (Tiger·tec Gold, 0° negative) — Walter Tools

The LNGX130720R-L55 WKP35G is a rectangular milling indexable insert engineered for efficient machining of steel and cast iron in production environments.

• Tiger·tec Gold coated carbide grade WKP35G
• Suited for machining steel and cast iron
• Rectangular insert with 2 mm corner radius
• 0° negative rake for stable cutting performance

Broader material capability for fewer tool changes

The insert uses the WKP35G grade within the Tiger·tec Gold family, a coated carbide formulation optimised for the demands of both steel and cast iron. The grade designation P/K reflects suitability for ISO groups P (steel) and K (cast iron), meaning the geometry and coating are tuned for the heat generation and chip behaviour typical of these materials. The practical benefit is reduced tooling variants in the tool room and fewer changeovers on the machine, supporting uninterrupted production and a higher net machining time.

Built for stable cutting and consistent surface finish

A 0° negative rake combined with the rectangular geometry and 2 mm corner radius delivers a robust cutting edge that resists chipping under interrupted cuts and heavy engagement. This geometry increases process stability and helps maintain a repeatable surface quality part after part. For users running medium to heavy milling operations, that stability translates directly into fewer secondary operations and consistent quality control results.

Controlled chips and extended tool life

The integrated L55 chipbreaker is designed to manage chip formation for the targeted material groups, promoting predictable swarf evacuation and lower risk of recutting. Paired with the Tiger·tec Gold coating, the insert demonstrates improved tool life by reducing abrasive and thermal wear. The economic effect is less frequent indexings or replacements, which reduces downtime and contributes to better overall equipment effectiveness.

Practical integration and handling in production systems

The rectangular plate form and compact profile allow straightforward clamping in suitable Walter toolholders and compatible milling systems. The insert’s execution supports standard indexable milling set-ups, enabling quick replacement and minimising fixture adjustments. Clear designation and tolerance class ensure consistent interchangeability in multi-shift operations, aiding logistics and process planning on the shopfloor.

FAQ

What materials is this insert designed to machine?
The insert is suitable for machining steel and cast iron; the WKP35G grade within the Tiger·tec Gold series is optimised for ISO material groups P and K.

How does the 0° negative rake affect performance?
A 0° negative rake provides a robust cutting edge that reduces chipping risk under heavy or interrupted cuts, improving process stability and surface consistency.

What is the role of the L55 chipbreaker?
The L55 chipbreaker promotes controlled chip formation for steel and cast iron, improving swarf management and reducing the chance of recutting.

Is the insert compatible with standard Walter toolholders?
The rectangular form and designation align with Walter’s indexable milling solutions; compatibility depends on the specific toolholder geometry and clamping system.

How does the Tiger·tec Gold coating influence tool life?
The Tiger·tec Gold coating increases wear resistance and thermal stability, which typically extends tool life and reduces frequency of indexings in production use.
