SNMX090408-F57 WKP35S milling indexable insert by Walter Tools — Tiger·tec Silver grade, square 90° geometry

The SNMX090408-F57 WKP35S is a square 90° milling indexable insert designed for productive machining of steel and cast iron, combining a coated carbide grade with a controlled chipbreaker for stable material removal.

• Tiger·tec Silver coated carbide grade WKP35S
• Suitable for steel and cast iron machining
• Square 90° insert with 0.8 mm corner radius
• Negative rake 0° for stable engagement

Greater process reliability through optimised coating and grade

The Tiger·tec Silver coating, paired with the WKP35S coated carbide grade, delivers improved resistance against abrasive wear and thermal loading common in milling steel and cast iron. For users seeking measurable process stability, the combination of coating technology and carbide substrate reduces flank wear and extends cutting edge life under typical production feeds. The designation P / K indicates suitability for the ISO groups P (steel) and K (cast iron), clarifying the insert’s intended material range and helping production planners select the correct geometry without ambiguity.

Stable cutting geometry for predictable machining results

A square 90° insert form with a 0.8 mm corner radius offers a balance between strength and profile definition: the corner radius increases edge robustness during intermittent cuts, while the square seat enables consistent indexability and repeatable orientation in the cutter body. The 0° negative rake provides a neutral engagement that lowers the risk of chatter and improves stability on heavy or interrupted cuts. These geometry choices translate into fewer tool changes and more consistent cycle times on medium- to heavy-duty milling operations.

Efficient chip control and economical throughput

The F57 chipbreaker is engineered to produce short, controllable chips when machining both steel and cast iron, contributing to safer chip evacuation and less manual intervention at the machine. In a production context, such chip control reduces downtime for clearing and improves machining reliability, which in turn supports higher net productivity. The insert’s series and grade focus on achieving long run lengths and consistent surface quality, making it a practical choice where repeatability and process economy are priorities.

FAQ

What materials is this insert intended for?
The SNMX090408-F57 WKP35S insert is specified for steel (P) and cast iron (K) applications in accordance with the grade’s capabilities.

How does the Tiger·tec Silver coating benefit machining?
The Tiger·tec Silver coating improves wear resistance and thermal stability, which extends edge life and supports more consistent performance across production runs.

What is the effect of the 0° negative rake on cutting?
A 0° negative rake offers neutral engagement that enhances stability, particularly beneficial for interrupted cuts or where a robust cutting edge is required.

Is the insert suitable for heavy milling or finishing?
The square 90° form with a 0.8 mm corner radius provides strength for heavier engagements while still enabling acceptable surface finishes when parameters are adjusted appropriately.

How is chip control managed with this insert?
The F57 chipbreaker is designed to produce short, manageable chips in both steel and cast iron, aiding evacuation and reducing the need for manual clearing.
