LNGX130720R-L55 WPP35G – milling indexable insert for steel machining, Walter Tools (Tiger‑tec Gold)

The LNGX130720R-L55 WPP35G is a rectangular milling insert designed for high‑performance cutting in steel applications, combining a wear‑resistant coating with a stable cutting geometry.

• Tiger‑tec Gold coating for long life
• L55 chipbreaker for controlled chips
• Rectangular form with 2 mm corner radius
• 0° negative rake for robust engagement

Extended lifetime through advanced coating and grade

The combination of the Tiger‑tec Gold coating and the WPP35G grade delivers a measured increase in wear resistance under standard steel machining conditions. The multi‑layer coating optimises heat resistance and reduces flank wear, which translates into fewer tool changes and higher machine utilisation. This technical balance between toughness and wear protection supports longer tool life while maintaining dimensional accuracy on components.

Stable cutting geometry for predictable results

A rectangular insert form with a 2 mm corner radius and a 0° negative rake provides mechanical strength at the cutting edge and reliable engagement in intermittent or heavy cuts. The geometry reduces the risk of chipping and supports stable metal removal when machining unalloyed and alloyed steel. This results in consistent surface finish and fewer scrap parts, making the insert well suited for both roughing and semi‑finishing operations where process reliability is essential.

Efficient chip control and process security

The L55 chipbreaker is engineered to produce manageable chip forms when cutting steel, improving evacuation and reducing downtime for chip clearing. Improved chip control lowers the likelihood of rework and protects machine tools and workpiece surfaces. Together with the coated carbide grade, this insert contributes to a predictable machining process and helps maintain steady cycle times over longer production runs.

Integration and handling in tool systems

The insert's ISO designation and rectangular form make it straightforward to integrate into standard milling tool holders and multi‑insert cutters. The nominal plate size and thickness ensure repeatable seating and clamping, while the robust edge preparation reduces handling damage during mounting. For process planning, the insert supports a range of cutting parameters typical for steel, offering a balance between cutting speed and tool life for production environments focused on throughput and repeatability.
