SCMT09T308-FM4 WMP20S Drehwendeschneidplatte – Walter Tools (Tiger‑tec Silver, for stainless steel)

SCMT09T308-FM4 WMP20S is a square indexable turning insert designed for reliable stainless steel machining in medium to robust conditions

• Tiger‑tec Silver coated carbide grade WMP20S
• Optimised for stainless steel machining
• 7° relief angle for secure cutting
• Square 90° insert with 0.8 mm corner radius

Consistent chip control and durable cutting edge for stainless steel

The SCMT09T308-FM4 WMP20S insert combines a Tiger‑tec Silver coating with a robust WMP20S substrate to address the specific demands of stainless steel. The coating technology reduces built-up edge and improves thermal resistance, which in turn supports stable chip formation and fewer interruptions in production. The integrated FM4 chipbreaker is engineered to form short, controllable chips under moderate to heavy turning conditions, helping to reduce manual chip handling and protect workpiece finish. This results in higher effective tool life and more predictable reconditioning intervals.

Geometry engineered for repeatable surface quality and edge protection

The insert’s square 90° geometry and 0.8 mm corner radius provide a balance between strength and finish: the larger corner radius increases edge stability for robust cuts while maintaining a consistent surface result. A 7° relief angle reduces radial forces and supports secure cutting action without excessive rubbing, which benefits both dimensional accuracy and insert life. The T3 thickness offers a solid seating in standard toolholders, improving clamping stability and repeatability across multiple indexings. These geometric choices make the insert suitable for facing, light profiling and general turning tasks where process reliability is essential.

Shop-floor efficiency through predictable performance and easy integration

Adopting this insert in production brings measurable gains: the coating and substrate pairing reduce the need for frequent edge changes, while the FM4 chipbreaker minimises secondary operations related to chip control. The result is improved throughput and fewer unscheduled stops, supporting higher overall productivity. Compatibility with common square indexable toolholders permits straightforward replacement and inventory harmonisation. For operations seeking reproducible results in stainless steel turning, this insert offers a pragmatic balance of process reliability and operational economy.

FAQ

What materials is this insert optimised for?
The insert is optimised for stainless steel; the WMP20S grade and Tiger‑tec Silver coating support secure chip formation and reduced built-up edge when machining stainless steels.

How does the FM4 chipbreaker affect machining?
The FM4 chipbreaker produces short, controllable chips in turning operations, improving safety at the machining centre and reducing the need for manual chip management.

What are the benefits of the 0.8 mm corner radius and square 90° shape?
A 0.8 mm corner radius increases edge strength for tougher cuts while the square 90° shape provides four usable cutting edges per index, supporting economical tool use and consistent surface quality.

Is this insert compatible with standard toolholders?
Yes; the SCMT09T308-FM4 WMP20S insert uses a common square seating and T3 thickness for secure clamping in compatible indexable turning toolholders.

How does the Tiger‑tec Silver coating improve performance?
The Tiger‑tec Silver coating enhances thermal resistance and wear control, which extends tool life and stabilises cutting performance in demanding stainless steel applications.
