LNGX130712R-L55 WPP35G Wendeplatten - Walter Tools

High-performance machining of steels is supported by the Tiger‑tec Gold coating and the WPP35G grade, while the L55 chipbreaker and 0° negative rake ensure stable chip formation and consistent surface quality; order the insert directly via Metav Werkzeuge or ask the technical consultants for tailored cutting data.

LNGX130712R-L55 WPP35G indexable milling insert – Tiger‑tec Gold for steel (Walter Tools)

The LNGX130712R-L55 WPP35G is a rectangular indexable milling insert designed for productive steel machining, combining a Tiger‑tec Gold coated carbide grade with an L55 chipbreaker for controlled chips.

• Tiger‑tec Gold coating for extended tool life
• Optimised L55 chip control for stable chips
• 0° negative rake for robust milling stability
• 1.2 mm corner radius for precision finishing

Productive performance for steel machining

The insert delivers a measurable increase in process reliability through its Tiger‑tec Gold technology and the WPP35G coated carbide grade. These characteristics make the component particularly suitable for machining steel where heat and chip formation are critical factors. The coated carbide substrate provides a balance between wear resistance and toughness, reducing flank wear and enabling longer tool life. By selecting a grade tailored to the P material group, operators will benefit from more predictable tool behaviour and fewer unplanned tool changes, which translates into higher machine utilisation and lower unit costs.

Stable chip control and surface quality

Optimised geometry and the L55 chipbreaker work together to produce consistent, short chips and to reduce the risk of built-up edge during interrupted cuts. The 0° negative rake contributes to a robust cutting edge that resists chipping under heavy engagement, while the corner radius 1.2 mm supports improved surface finish and edge strength. These features mean fewer rework cycles and a more reliable finish straight off the machine, which is particularly valuable in production runs where repeatability and part quality are essential.

Integration into productive tool systems

The rectangular format and the specified dimensions allow straightforward integration into standard milling cutters and toolholders designed for this insert shape. The design supports stable clamping and repeatable indexability, simplifying tool management on the shop floor. Complementary process data from Metav Werkzeuge’s technical advisors can help select cutting speeds and feed rates that match the workpiece grade and machining strategy, ensuring the full potential of the insert is realised while preserving tool life and achieving consistent part tolerances.

FAQ

What materials is this insert suited for? The LNGX130712R-L55 WPP35G is formulated for the P material group and is optimised for machining steel, providing good performance with unalloyed and alloyed steels.

How does the Tiger‑tec Gold coating affect tool life? The Tiger‑tec Gold coating on this insert reduces wear and improves thermal stability, which typically extends tool life and maintains consistent cutting performance under standard steel machining conditions.

What advantage does the 0° negative rake offer? A 0° negative rake increases cutting-edge robustness and resistance to chipping, making the insert suitable for heavier engagement and interrupted milling operations.

Can this insert improve surface finish? Yes; the combination of the L55 chipbreaker and the 1.2 mm corner radius contributes to controlled chip evacuation and a stable cutting edge, which aids in achieving a better surface finish.

Is the LNGX130712R-L55 WPP35G compatible with standard toolholders? The rectangular shape and standardised dimensions of the insert are intended for conventional milling holders that accept this geometry; verify holder compatibility with the insert designation.
