LNGX130716R-L55 WKP25S milling insert (Tiger‑tec Silver, for steel & cast iron) — Walter Tools

The LNGX130716R-L55 WKP25S is a rectangular indexable milling insert designed for productive machining of steel and cast iron, combining a coated carbide grade with an L55 chipbreaker for reliable chip control

• Tiger‑tec Silver coating for long tool life
• Designed for steel and cast iron machining
• 0° negative rake for stable cutting
• 1.6 mm corner radius for robust edge

High cutting performance for consistent productivity

The coated carbide grade WKP25S from the Tiger‑tec Silver series delivers predictable wear behaviour and dependable edge stability. As an indexable milling insert with a 0° negative rake, it provides controlled cutting forces and reduced vibration, which helps maintain tolerances during heavy or interrupted cuts. The integrated L55 chipbreaker aids reliable chip formation when machining P- and K-group materials, resulting in fewer tool changes and improved process stability on high-volume production runs.

Application advantages and material compatibility

Engineered for the machining of steel and cast iron, this rectangular insert is suited to common turning and face‑milling operations encountered in component manufacturing and toolrooms. The geometry supports the formation of short, controllable chips in cast iron and manages the thermal loads typical of steel cutting, which enhances surface finish and dimensional repeatability. For workshop planners and production engineers, the insert’s specification simplifies selection: coated carbide grade, chipbreaker type L55, and a 1.6 mm corner radius indicate a balance between robustness and finish quality.

Durability, handling and cost-efficiency in production

The combination of a modern coating system and a resistant carbide substrate gives this insert extended edge life under typical industrial conditions, reducing downtime and tooling costs. The 1.6 mm corner radius increases edge strength for intermittent cuts while the rectangular format permits straightforward index changes, limiting setup complexity. These factors make the insert an economical choice where process reliability and repeatable results are priorities, contributing to a smoother production flow and predictable machining cycles.

FAQ

What materials is this insert suitable for?
The LNGX130716R-L55 WKP25S insert is intended for machining steel (P) and cast iron (K), utilising the Tiger‑tec Silver coated carbide to manage heat and abrasive wear.

How does the 0° negative rake affect performance?
A 0° negative rake gives the insert a stable cutting geometry that reduces chatter and supports interrupted cuts; the Walter Tools grade WKP25S benefits from this configuration during robust milling operations.

Which chipbreaker is integrated and what is its purpose?
The insert features an L55 chipbreaker designed for controlled chip formation in common steel and cast‑iron applications, improving surface quality and preventing long, tangled chips.

Can this insert be used for finishing and roughing operations?
With its 1.6 mm corner radius and coated carbide grade, the insert offers a compromise between robustness for roughing and the capability to produce respectable finishes in many production scenarios.

Is the LNGX130716R-L55 WKP25S compatible with standard rectangular toolholders?
Yes, the rectangular format is compatible with holders designed for this geometry; check holder seating and clamping specifications against the LNGX130716R-L55 designation for correct fitment.
