SCGT09T308-MM4 WSM01 turning insert — Tiger‑tec Silver, chipbreaker MM4 by Walter Tools

The SCGT09T308-MM4 WSM01 is a square 90° turning insert engineered for heavy-duty machining of stainless steel and heat‑resistant superalloys, offering reliable edge life and reproducible performance.

• Tiger‑tec Silver coating for wear resistance
• MM4 chipbreaker for secure chip control
• 7° relief angle for robust edge stability

High cutting performance for demanding materials

The insert is designed around the Tiger‑tec Silver concept to deliver consistent wear resistance and stable cutting-edge behaviour when machining tough alloys. Its coated carbide construction and the WSM01 grade combine to reduce edge breakdown and support predictable tool life, which translates into fewer tool changes and improved process efficiency. By focusing on measurable process gains — such as longer time between indexings and stable surface finish — the insert supports productive machining sequences in industrial turning operations.

Secure chip control that stabilises the process

With the MM4 chipbreaker, the geometry channels chips away from the cutting zone to avoid entanglement and interruption. This chip control enhances coolant access and reduces the risk of built‑up edge formation during interrupted cuts or when working with gummy materials. The feature particularly benefits setups where machine uptime and repeatability are critical, enabling operators to maintain steady feeds and speeds while achieving reproducible results.

Edge geometry tuned for strength and versatility

A 7° relief angle combined with a corner radius of 0.8 mm gives a robust cutting edge that tolerates higher mechanical loads and thermal stresses. The square 90° plate shape is suitable for general‑purpose turning where a stable cutting seat is required. These geometry choices help deliver a balance between strength and finishing capability, making the insert appropriate for roughing and semi‑finishing operations on stainless steel and similarly challenging materials.

Application range and material compatibility

The grade and geometry support machining of ISO material groups M and S — specifically stainless steel (M) and heat‑resistant superalloys/titanium (S). The combination of high process reliability and optimised chip formation makes the insert a practical choice when consistent performance is required under elevated cutting temperatures and poor thermal conductivity conditions. Operators benefit from a tool that reduces variability in cycle times and helps maintain quality across batches.

Practical handling and workshop integration

The insert follows standard ISO indexing conventions and integrates with established toolholder systems for quick insert changes and minimal downtime. Its predictable behaviour reduces setup iteration and simplifies grade selection for job planning. For procurement, the standardised designation enables streamlined inventory management and traceability across production lines.
