SNMX120512-D27 WKP35G - Milling insert, Tiger·tec Gold coating by Walter Tools

A SNMX120512-D27 WKP35G milling insert engineered for robust shoulder and face milling, offering reliable chip control and long wear life in steel and cast iron applications

• Tiger·tec Gold coating for long tool life
• Optimised D27 chipbreaker geometry
• Square 90° insert for shoulder milling
• Suited for steel and cast iron machining

Outstanding productivity through advanced grade and coating

The combination of the WKP35G grade with Tiger·tec Gold technology gives this insert a coated carbide surface that improves wear resistance and maintains a stable cutting edge under demanding conditions. The multilayer coating reduces abrasive wear and helps to retard thermal damage during continuous milling, which results in fewer tool changes and longer productive cycles. In practice, that means more consistent component quality and lower process-related downtime, particularly on medium-to-high volume production runs where repeatable performance is critical. The insert’s design supports predictable tool life, aiding planning and cost-efficiency across production batches.

Consistent chip control and secure cutting geometry

The square 90° format together with the D27 chipbreaker provides reliable chip formation and evacuation during shoulder and face milling operations. A 1.2 mm corner radius delivers robust edge strength for moderate to heavy engagement while the 0° (negative) relief angle increases robustness for interrupted cuts and heavy radial depths of cut. These geometric choices improve stability at the cutting edge and reduce the likelihood of edge chipping when machining complex contours or interrupted surfaces. The net effect is a balance between good surface finish and tool resilience, with chip control that supports safer, more predictable machining cycles on demanding workpiece geometries.

Application guidance for steel and cast iron with reliable process results

Designed specifically for ISO groups P and K, the insert is optimised for machining steel and cast iron, where thermal loading and abrasive wear are typical concerns. The SNMX120512-D27 WKP35G is suitable for shoulder milling, face milling and similar operations where robust edge life and chip control matter. To exploit the insert’s advantages, pair it with rigid toolholding and stable workpiece setups; moderate depths of cut combined with steady feed rates typically deliver the best compromise between removal rate and tool life. For production environments seeking process reliability, this insert reduces unplanned stops and supports predictable output, making it a practical choice for workshops aiming for consistent part quality and throughput. Technical application support is available through Metav Werkzeuge for fine‑tuning cutting data to a specific machine and material combination.

FAQ

What materials is this insert suited for?
The SNMX120512-D27 WKP35G is optimised for steel (ISO group P) and cast iron (ISO group K), matching the wear and chip formation characteristics of those materials.

How does the Tiger·tec Gold coating help in production?
The Tiger·tec Gold coating on the WKP35G grade improves wear resistance and thermal stability, which extends tool life and supports more consistent machining cycles.

What milling applications suit a square 90° insert?
A square 90° insert is ideal for shoulder milling and face milling where a strong cutting edge and reliable indexing are required.

Why is the 0° (negative) relief angle advantageous?
A 0° (negative) relief increases edge robustness for interrupted cuts and heavy engagement, reducing the risk of chipping under shock loads.

Is there support for selecting cutting data for specific machines?
Yes, Metav Werkzeuge can advise on cutting parameters and setup to match the SNMX120512-D27 WKP35G to a given machine and workpiece material.
