CCMT09T308-E47 WSM20S Drilling/boring indexable insert — Tiger·tec Silver grade (Walter Tools)

A CCMT09T308-E47 WSM20S indexable insert designed for drilling and boring applications in hard-to-machine materials and stainless steel

• Tiger·tec Silver coated for high thermal resistance
• Optimised E47 chipbreaker for stable chips
• Rhombic 80° geometry for versatile engagement
• 0.8 mm corner radius for enhanced edge strength

High-performance cutting in demanding alloys

The Tiger·tec Silver grade WSM20S delivers improved heat resistance and wear behaviour when machining stainless steels and high-temperature alloys. The coated carbide construction supports a stable cutting edge under elevated temperatures, reducing flank wear and the risk of built-up edge. Thanks to the E47 chipbreaker and the Rhombic 80° form, the insert controls chip flow during drilling and boring, lowering the likelihood of clogging and enabling smoother evacuation of swarf. This results in more predictable cycle times and fewer interrupted operations.

Process security and extended tool life

A combination of a 7° relief angle and a 0.8 mm corner radius offers robustness at the cutting edge, helping to withstand the high cutting forces typical for heat-resistant materials. The Walter grade focuses on secure chip formation and consistent edge stability, which translates into fewer insert changes and less machine downtime. The design supports reproducible results across batches, improving overall process reliability and reducing the total cost per hole over longer production runs.

Practical selection and machining guidance

For roughing and medium-finishing operations in alloys categorised as ISO groups M (stainless steels) and S (superalloys, titanium), choose the WSM20S grade to balance wear resistance and toughness. The Rhombic 80° geometry permits flexible cutting conditions and variable approach angles commonly used in drill- and bore-related toolholders. When pairing with the appropriate drill body or boring bar, the insert’s chip control features support stable cutting at moderate to high feeds; this reduces vibration and aids surface integrity without complex process changes.

FAQ

What materials is this insert suitable for?
The CCMT09T308-E47 WSM20S is specified for ISO groups M and S, meaning it is suitable for stainless steels and heat-resistant superalloys or titanium where thermal resistance and edge stability are required.

How does the E47 chipbreaker affect drilling performance?
The E47 chipbreaker on this Walter Tools insert promotes controlled chip formation and evacuation during drilling and boring, which reduces clogging and supports steady cutting forces for improved process security.

What cutting conditions favour the WSM20S grade?
WSM20S performs well at moderate to high cutting temperatures and is recommended for roughing to medium finishing in tough-to-machine materials; its coated carbide composition balances wear resistance with toughness.

Is the 0.8 mm corner radius suitable for finishing?
The 0.8 mm radius provides edge robustness and is well suited to stable cutting where surface integrity is important; for very fine finishes a smaller radius may be chosen if available in the system.

Which series does this insert belong to and what does that mean?
This insert is part of the Tiger·tec Silver series by Walter Tools, indicating a coated carbide concept engineered for enhanced thermal stability and consistent tool life in demanding applications.
