SNMG120412-FM5 WMP20S — Drehwendeschneidplatte (square 90°) for rostfreier Stahl by Walter Tools

The SNMG120412-FM5 WMP20S is a square 90° indexable turning insert engineered for medium to robust turning of rostfreier Stahl, offering stable chip formation and long-lasting performance.

• Tiger·tec Silver coated carbide
• Grade WMP20S for rostfreier Stahl
• Negative 0° free angle for stability
• 1.2 mm corner radius for edge strength

Consistent performance for rostfreier Stahl with optimised chip control

The combination of the Tiger·tec Silver coating and the WMP20S grade targets the specific demands of rostfreier Stahl, which tends to be tough and prone to built-up edge. The integrated FM5 chipbreaker supports reliable chip formation, reducing the risk of stringing and improving evacuation under medium to heavy cutting conditions. This engineering leads to a more predictable process window and fewer interruptions for rework, translating into higher net output per shift.

Robust geometry that reduces downtime and increases tool life

The square 90° configuration with a 1.2 mm corner radius and negative 0° free angle creates a strong cutting edge that resists chipping during interrupted cuts and heavier feed rates. As an indexable insert, the design allows multiple cutting edges per insert, lowering tool change frequency and setup time. The specified geometry supports secure clamping and repeatable orientation in standard SNMG-compatible toolholders, so cycling between edges is quick and maintains consistent part quality.

Process reliability, repeatability and material-focused coating benefits

The coated carbide composition from the Tiger·tec Silver series provides improved wear resistance and thermal stability compared with uncoated grades, resulting in steady performance across batch runs. This means fewer variations in surface finish and prolonged edge life when machining rostfreier Stahl in demanding production environments. The clear material focus and optimized chip control combine to support both productivity and quality targets, making the insert a pragmatic choice for shops seeking reproducible results.

FAQ

Is this insert suitable for rostfreier Stahl machining?
Yes. The SNMG120412-FM5 WMP20S is specifically graded and coated for machining rostfreier Stahl, providing improved chip control and edge security.

What does the FM5 chipbreaker achieve?
The FM5 chipbreaker promotes controlled chip formation for medium to robust cutting, enhancing evacuation and reducing the risk of built-up edge when cutting rostfreier Stahl.

How does the Tiger·tec Silver coating affect performance?
Tiger·tec Silver increases wear resistance and thermal stability, which helps maintain cutting-edge integrity and consistent surface finish during longer cycles.

What are the benefits of the negative 0° free angle and 1.2 mm corner radius?
The negative 0° free angle and 1.2 mm corner radius create a strong edge geometry that resists chipping under load and supports robust turning operations with reliable repeatability.

Will this insert fit standard SNMG toolholders?
The insert follows SNMG geometry and is intended for toolholders that accept SNMG indexable inserts; compatibility should be confirmed with the specific toolholder specifications.
