SCGT09T308-FM2 WSM20S – turning indexable insert (Tiger·tec Silver) by Walter Tools

The SCGT09T308-FM2 WSM20S is a square 90° turning insert designed for heavy-duty machining of stainless steels and heat-resistant superalloys and titanium.

• Tiger·tec Silver coating technology
• WSM20S grade for stainless and superalloys
• FM2 chipbreaker for stable chip control
• 0.8 mm corner radius, square 90°

High performance where heat and toughness meet

The insert combines a coated carbide substrate with the Tiger·tec Silver technology, engineered for secure cutting in materials that generate heat and work-harden, such as stainless steels and heat-resistant superalloys. The WSM20S grade promotes a stable cutting edge and consistent wear behaviour, which translates into predictable tool life and fewer interruptions on the shop floor. This results in a more reliable process window and supports higher productivity in serial production and batch machining environments.

Geometry engineered for secure cutting and surface quality

A compact square 90° form with a 0.8 mm corner radius and a 7° clearance angle provides a robust cutting edge that resists chipping while maintaining good surface finish. The FM2 chipbreaker is designed to encourage short, controllable chips under moderate to heavy cutting depths, reducing the risk of built-up edge and improving swarf evacuation. Together, these geometry choices reduce the likelihood of unplanned tool changes and help maintain consistent part tolerances, particularly when machining sticky or gummy grades.

Practical advantages for workshop efficiency

The insert’s specification—thin-profile T3 thickness and tolerance class G—makes it compatible with common toolholder systems while offering the rigidity required for interrupted or heavy cuts. The coated surface reduces friction and improves thermal stability, allowing for stable cutting parameters in challenging materials. In production terms, this means fewer set-up iterations and a smoother transition from prototype to series manufacture. For shops seeking reproducibility and economy, the insert supports repeatable performance and predictable maintenance scheduling.

FAQ

What materials is this insert designed for?
The SCGT09T308-FM2 WSM20S insert from Walter Tools is optimised for stainless steels (ISO group M) and heat-resistant superalloys and titanium (ISO group S).

How does the FM2 chipbreaker influence cutting performance?
The FM2 chipbreaker on the SCGT09T308-FM2 promotes short, controlled chips and aids chip evacuation, which lowers the risk of built-up edge and improves process stability when machining tougher materials.

What does the Tiger·tec Silver coating provide?
Tiger·tec Silver enhances thermal resistance and lubricity on the cutting edge, helping the WSM20S grade maintain a stable edge life under elevated temperatures and adhesive wear conditions.

Is the 0.8 mm corner radius suitable for finishing?
A 0.8 mm corner radius balances edge strength and surface finish; it is robust enough for heavier cuts while still capable of producing acceptable surface quality in semi-finish to finish operations.

Which toolholders are compatible with this insert format?
The square 90° form and size 09 of this turning insert are compatible with standard indexable insert toolholders designed for SCGT-style inserts; check clamping and seat geometry for precise fit.
