CCMT09T308-FM4 WSM10S indexable insert — Walter Tools, Tiger·tec Silver, Rhombus 80°, 0.8 mm radius

The CCMT09T308-FM4 WSM10S is an indexable turning and boring insert designed for demanding machining of rostfreie Stähle and heat‑resistant superalloys, featuring the Tiger·tec Silver coating and an FM4 chipbreaker for secure chip control

• Tiger·tec Silver coating for longer tool life
• FM4 chipbreaker for controlled chips and surface finish
• Rhombus 80° geometry for versatile turning applications
• 0.8 mm nose radius for improved edge strength

High reliability from coating and grade

The combination of the Tiger·tec Silver coating and the WSM10S grade delivers improved wear resistance and thermal stability during interrupted cuts and continuous turning. The coating reduces flank wear and helps maintain a stable cutting edge when machining rostfreie Stähle and heat‑resistant alloys, which are prone to work hardening and high cutting temperatures. As a result, tool life is extended and machining runs with fewer insert changes, supporting predictable production cycles and lower tooling downtime.

Precise chip control for safer production

Equipped with the FM4 chipbreaker, this insert produces short, manageable chips under a wide range of cutting conditions. The chip control geometry reduces the risk of entanglement and scatter, improving operator safety and simplifying chip evacuation in automated and manual turning operations. Controlled chips also contribute to a consistent surface finish, reducing the need for secondary processing and supporting efficient downstream workflows.

Geometry and edge design for productivity

The Rhombus 80° form with a 0.8 mm corner radius balances strength and versatility: it allows secure entry angles for general turning while maintaining edge robustness during interrupted cuts. The 7° clearance angle minimises rubbing and helps prevent excessive heat generation at the flank face. Together, these geometric choices enable higher cutting parameters with reliable results, particularly when combined with a suitable toolholder and cutting data adapted for stainless steels and difficult‑to‑cut alloys.

Application guidance and machining benefit

Selecting this insert supports a productivity‑oriented machining strategy for demanding materials. The coated, WSM10S grade is suitable for applications where stable chip formation and thermal resistance are required, such as automotive components, valve bodies and aerospace parts made from rostfreie Stähle or high‑temperature alloys. By focusing on cutting parameter optimisation and appropriate coolant strategy, the insert can deliver consistent surface quality and repeatable tool life, reducing overall process variability.

FAQ

What materials is this insert suited for?
The CCMT09T308-FM4 WSM10S insert from Walter Tools is designed primarily for rostfreie Stähle (ISO group M) and heat‑resistant superalloys/titanium (ISO group S), offering thermal stability and controlled chip formation.

How does the Tiger·tec Silver coating improve performance?
The Tiger·tec Silver coating on the WSM10S grade reduces abrasive and adhesive wear, improving edge life during high‑temperature cuts and making the insert suitable for sustained machining of tough alloys.

Which operations benefit most from the FM4 chipbreaker?
Turning and light boring operations with a need for short, curled chips benefit most; the FM4 chipbreaker ensures predictable chip flow and better surface finish with fewer secondary steps.

Can the insert handle interrupted cuts?
Yes — the 0.8 mm nose radius and the WSM10S grade provide a robust cutting edge that tolerates moderate interruptions while maintaining stable performance.

Is the Rhombus 80° geometry versatile for different turning tasks?
The Rhombus 80° shape is well suited for general turning profiles and offers favourable entry angles for both conventional and semi‑finish operations, making it a flexible choice for many workshops.
