LNMX201012R-F27T WKP35S milling indexable insert — Tiger‑tec Silver coated grade for steel and cast iron, Walter Tools

The LNMX201012R-F27T WKP35S is a rectangular milling insert engineered for robust roughing and medium-finishing operations on steel and cast iron, combining a proven chipbreaker with a 0° negative rake for secure cutting performance.

• Tiger‑tec Silver coated carbide grade WKP35S
• Optimised F27T chipbreaker for stable chips
• Rectangular form with 1.2 mm corner radius
• 0° negative rake for heavy‑duty roughing

Increase throughput with consistent wear resistance

The combination of the Tiger‑tec Silver coating and the WKP35S carbide composition is designed to deliver stable wear behaviour under the thermal and mechanical stresses typical of machining steel and cast iron. This results in longer tool life and fewer index changes, which directly reduces machine idle time and tooling costs. The coating technology improves resistance to abrasive wear and helps maintain a sharp cutting edge, so frequent regrinding or premature replacement is avoided. For production environments seeking predictable process control, this insert supports consistent component quality over extended tool cycles.

Optimised chip control and secure cutting action

Thanks to the F27T chipbreaker and the 0° negative rake, chip formation is controlled even under interrupted or heavy cuts, reducing the risk of built‑up edge and unstable chip evacuation. The 1.2 mm corner radius provides a balance between edge strength and surface finish, allowing sheltered edges to resist shock loads while still delivering acceptable part quality. Improved chip flow lowers the chance of recutting and reduces secondary operations, which benefits both cycle time and operator safety. The insert’s geometry aids in achieving reproducible surface integrity with fewer process adjustments.

Robust format and straightforward integration into tool systems

The rectangular shape and the solid 10 mm thickness ensure mechanical rigidity for demanding milling tasks; the nominal 20 mm size and tolerance class M allow for accurate seating and repeatable positioning in standard toolholders. The grade is specified for material groups P (steel) and K (cast iron) according to ISO classifications, which simplifies tool selection for mixed‑material production runs. With this insert, set‑up time is reduced and clamping stability is enhanced, which supports higher feed rates and productive metal removal. The execution marked as X denotes the standard configuration delivered for common industrial tool sets.

FAQ

Which materials are recommended for this insert?
The LNMX201012R‑F27T WKP35S insert from Walter Tools is specified for steel (P) and cast iron (K) applications and is formulated to handle the typical chip and heat behaviours of those groups.

What benefits does the Tiger‑tec Silver coating offer?
Tiger‑tec Silver on the WKP35S grade provides enhanced abrasion resistance and improved edge security, extending tool life and supporting stable cutting for high‑volume production with the Walter Tools insert.

How does the F27T chipbreaker affect machining?
The F27T chipbreaker promotes controlled chip formation and evacuation, reducing recutting and improving surface consistency when the LNMX201012R‑F27T insert is used in intermittent or heavy‑cut milling.

Is the 0° negative rake suitable for roughing?
Yes, the 0° negative rake increases edge strength and mechanical stability, making the insert particularly suitable for heavy‑duty roughing operations and interrupted cuts.

What mounting accuracy can be expected with this insert?
With a tolerance class M and a rectangular format, the insert offers repeatable seating and stable clamping for consistent tool positioning in compatible holders.
