TCMT16T304-FM4 WSM20S indexable insert — Tiger·tec Silver, for rostfreier Stahl & superalloys — Walter Tools

TCMT16T304-FM4 WSM20S is an indexable insert engineered for drilling/reaming and turning operations on hard-to-machine materials, optimised for thermal stability and robust cutting-edge performance

• Tiger·tec Silver coating for thermal stability
• FM4 chipbreaker for controlled chip flow
• 0.4 mm corner radius for edge strength
• Triangle 60° format for versatile turning
• Suitable for rostfreier Stahl and superalloys

Stable cutting performance for demanding materials

This indexable insert is designed to provide consistent cutting performance when machining difficult materials. The WSM20S grade, a coated carbide in the Tiger·tec Silver series, is formulated to resist heat and maintain edge integrity, which reduces the risk of built-up edge and unpredictable tool wear. For workshop planners and production engineers, this means fewer interruptions and more predictable cycle times; the FM4 chipbreaker further ensures stable chip formation, improving surface finish and reducing the need for manual chip handling.

Coating and grade deliver longer tool life

The Tiger·tec Silver coating enhances heat resistance and oxidation protection at the cutting edge. Combined with the WSM20S substrate, the insert achieves a balance between hardness and toughness that is particularly effective on rostfreier Stahl and heat-resistant alloys. Explained simply: the coating acts as a thermal barrier while the substrate provides mechanical support, resulting in extended tool life and fewer insert changes during production runs, which lowers downtime and increases overall process efficiency.

Geometry tailored for reliable turning and drilling

Geometry plays a decisive role in performance: the triangle 60° shape offers stable positioning in standard tool holders, while the 0.4 mm corner radius supplies extra edge strength for interrupted cuts. A 7° relief angle helps to reduce rubbing and power draw, and the T3 thickness ensures consistent clamping and repeatable machining results. These design choices combine to give machinists a predictable cutting experience and make the insert suitable for a range of operations where robustness and repeatability are required.

Practical application guidance and compatibility

The insert is suitable for applications classified under ISO groups M and S, covering rostfreier Stahl as well as heat-resistant superalloys and titanium. In practice, this translates to use in industries such as aerospace, energy and specialised medical component machining where materials are challenging and tolerances are tight. When selecting cutting parameters, favour moderate speeds with attention to tool engagement and coolant strategy to exploit the coating’s thermal benefits while maintaining chip control via the FM4 breaker.

FAQ

What materials is this insert best suited for?
The TCMT16T304-FM4 WSM20S is optimised for rostfreier Stahl and for heat-resistant superalloys (ISO groups M and S), providing reliable chip control and edge stability on tough materials.

How does the Tiger·tec Silver coating benefit machining?
The Tiger·tec Silver coating on the WSM20S grade improves thermal resistance and oxidation protection, which helps maintain a stable cutting edge and extends insert life under elevated temperatures.

Is the FM4 chipbreaker suitable for finishing passes?
Yes, the FM4 chipbreaker is designed to produce controllable chips and a consistent surface finish; its geometry balances chip control with the potential for fine finishing when combined with suitable feeds and speeds.

What does the 0.4 mm corner radius mean for tool life?
A 0.4 mm corner radius provides greater edge strength against mechanical shock and wear, helping to prolong tool life in applications with intermittent cuts or variable engagement.

Can this insert be used in standard triangle tool holders?
The triangle 60° format is compatible with common indexable insert holders for triangular inserts; ensure the clamping system matches the TCMT designation and thickness T3 for secure seating.
