SNMX090408-F27 WKP35S Milling insert (Square 90°, Tiger·tec Silver) – Walter Tools

A SNMX090408-F27 WKP35S indexable milling insert engineered for productive machining of steel and cast iron in demanding industrial applications

• Tiger·tec Silver coating for wear resistance
• Suitable for steel (P) and cast iron (K)
• Square 90° form with 0.8 corner radius
• Negative 0° rake for stable cutting

Consistent performance across steel and cast iron for reliable throughput

The Walter grade WKP35S, produced in the Tiger·tec Silver family, is optimised to handle the thermal and mechanical demands typical of machining steel and cast iron. As an indexable insert, it combines a coated carbide substrate with a robust surface layer that resists both adhesive and abrasive wear, which translates into longer cutting intervals and more predictable tool life. This stability supports higher machine utilisation and reduces unplanned downtime, making the insert a rational choice where consistent productivity matters.

Geometry that secures edges under load and supports repeatable results

A square 90° plate form and a 0.8 mm corner radius create a geometry focused on edge strength and versatility in slotting, roughing and shoulder milling. The negative 0° rake increases cutting-edge robustness and damps vibration during interrupted cuts, while the square format provides four usable corners for economy per index. Together these features enhance process security and enable repeatable part quality in batch production and mixed-volume work.

Practical advantages for shop-floor integration and inventory control

Using a standard ISO-style insert designation simplifies tool management: the compact designation SNMX090408-F27 WKP35S aligns with common toolholders and clamping systems, reducing changeover complexity. The coated grade supports predictable wear behaviour, which aids in tool-life planning and cost calculations. For operations seeking to raise throughput, the combination of reliable edge stability and established coating technology reduces the frequency of tool exchanges and supports continuous production flow.

Coating technology explained for better application decisions

The Tiger·tec Silver coating is a multi-layer, PVD-style technology designed to improve surface hardness and thermal resistance while maintaining a stable chip formation behaviour on both steel and cast iron. The WKP35S grade is a coated carbide variant tuned for the heat and chip characteristics given by ISO material groups P and K. In practice this means fewer unexpected tool failures and improved surface finishes under comparable cutting conditions, especially when cutting speeds and feed rates are optimised for the respective workpiece material.

FAQ

Which materials can this insert machine efficiently?
The SNMX090408-F27 WKP35S is specified for machining steel (ISO group P) and cast iron (ISO group K); the coating and substrate combination is selected to handle the thermal and abrasive conditions of these materials.

What does the Tiger·tec Silver coating deliver in shop practice?
Tiger·tec Silver improves resistance to adhesive and abrasive wear and supports stable chip formation; in combination with the WKP35S grade it helps to extend cutting intervals and maintain surface quality on both steel and cast iron parts.

Why is the 0.8 corner radius important for industrial milling?
A 0.8 mm corner radius increases the cutting-edge strength and reduces the risk of chipping under load, which is beneficial for interrupted cuts and operations that demand robust edge endurance.

Is the square 90° geometry suitable for shoulder milling and slotting?
Yes; the square 90° form provides a strong cutting edge for shoulder milling and slotting, and offers multiple indexable corners for economic use of the insert.

What information helps to select the right insert grade for a job?
Consider the workpiece material (P / K), the cutting conditions (feed, speed, interrupted cuts), and the required surface finish; the SNMX090408-F27 WKP35S is tuned for steel and cast iron where wear resistance and edge stability are priorities.
