LNHU160712R-L55T WKP35S rectangular milling insert — Tiger‑tec Silver, Walter Tools

LNHU160712R-L55T WKP35S is a rectangular, negative‑rake milling insert designed for productive machining of steel and cast iron in industrial milling applications

• Tiger‑tec Silver coated grade WKP35S
• Optimised chipbreaker L55T for stable chips
• Suitable for steel (P) and cast iron (K)
• 0° negative relief for robust cutting performance

Increased productivity through controlled chip formation

The LNHU160712R-L55T WKP35S insert combines a coated carbide grade with a dedicated chipbreaker L55T, delivering reliable chip control under varying cutting conditions. The Tiger‑tec Silver coating reduces adhesive wear and supports consistent surface quality, while the rectangular geometry ensures stable clamping in indexable milling cutters. For production environments this means fewer interruptions for chip clearing and a steadier cycle time, which translates directly into improved throughput and process stability.

Reliable performance across steel and cast iron

The cutting grade is optimised for the ISO groups P (steel) and K (cast iron), so the insert performs well on both unalloyed and alloyed steels as well as abrasive cast materials. The WKP35S formulation balances toughness and wear resistance to handle the thermal and mechanical loads typical in steel machining and the brittle, breaking chips of cast iron. Explaining the term: a chipbreaker like L55T shapes and breaks the chip into manageable lengths, reducing risk of entanglement and improving evacuation in high‑volume milling.

Geometry engineered for tool life and surface quality

A corner radius of 1.2 mm and a negative 0° relief create a robust cutting edge that resists chipping in interrupted cuts and heavy engagement scenarios. The insert’s thickness 07 and rectangular form factor provide secure seating and repeatable positioning in compatible indexable milling cutters. Together, these geometric choices support longer tool life and consistent part finish, reducing the need for frequent insert changes and helping to maintain dimensional accuracy in series production.

Practical integration and benefits for the workshop

Adopting this insert offers straightforward benefits for CNC milling setups: the coated, grade‑matched insert helps to lower tooling costs per component through extended cutting intervals, while the chip control strategy reduces cycle variability. The insert’s characteristics suit both roughing and semi‑finishing operations where predictable wear behaviour and process security are priorities. For teams planning tool setups, the combination of Tiger‑tec Silver technology and the WKP35S grade makes this insert a reliable option for mixed‑material production runs.

FAQ

What materials is this insert suitable for?
The LNHU160712R-L55T WKP35S insert is specified for ISO groups P and K, meaning it is suitable for machining steel and cast iron.

What does the chipbreaker L55T do?
The L55T chipbreaker is designed to form and split chips into short, controllable segments, improving evacuation and reducing the risk of chip-related interruptions during milling.

How does the 0° negative relief affect cutting?
A 0° negative relief creates a stronger cutting edge and higher edge support, which is beneficial in interrupted cuts and heavy milling where edge robustness and stability are required.

Is the WKP35S grade coated?
Yes, WKP35S is a coated carbide grade utilising Tiger‑tec Silver technology to enhance wear resistance and process reliability in demanding milling applications.

Which toolholders are compatible with this rectangular insert?
Compatibility depends on the insert seat and clamping system; the LNHU160712R‑L55T geometry fits holders designed for that designation—consult cutter manufacturer specifications or Metav Werkzeuge for matching toolholder options.
