CCMT09T308-MW4 WSM20S Indexable Turning Insert — Tiger‑tec Silver, 7° clearance (Walter Tools)

The CCMT09T308-MW4 WSM20S is an indexable turning insert designed for demanding turning of stainless steel and high‑temperature alloys, offering a balanced geometry for reliable chip control.

• Tiger‑tec Silver coating for thermal resistance
• Suitable for stainless steel and superalloys
• MW4 chipbreaker for stable chip formation
• 0.8 mm corner radius for edge strength

Consistent chip control for uninterrupted production

The combination of the MW4 chipbreaker with the insert’s geometry delivers predictable chip formation, reducing the risk of built‑up edge and machine downtime. This makes the component particularly effective in continuous turning operations where consistent evacuation of chips matters. The insert’s design helps maintain a stable cutting zone, which in turn enables more reliable cycle times and fewer reworks — a tangible efficiency gain for production lines machining stainless steel and similar tough materials.

Material compatibility that reduces process risk

Selected for the ISO groups M and S, this grade supports machining of stainless steels and heat‑resistant superalloys or titanium. The WSM20S grade, part of the Tiger‑tec Silver family, is tuned to withstand high temperatures and to preserve the cutting edge under heavy thermal load. For engineers less familiar with ISO groupings: M denotes stainless steels (materials prone to toughness and adhesion) and S denotes superalloys and titanium (materials that challenge heat dissipation). Choosing the right insert grade minimises edge wear and supports repeatable results across batches.

Coating and grade that lower running costs

The WSM20S coating technology improves thermal resistance and edge stability, which translates into longer intervals between indexings and less frequent insert changes. Longer tool life and predictable wear behaviour contribute directly to lower tooling costs per component and reduced non‑productive time. For workshops aiming to increase throughput without compromising surface quality, the coated grade provides a measurable return on process reliability when turning demanding alloys.

Practical geometry for secure tool performance

With a rhombus 80° form, 7° clearance and a 0.8 mm corner radius, the insert offers a compromise between versatility and robustness. The 80° shape supports a range of turning engagements while the modest corner radius improves resistance to edge breakdown under interrupted cuts. The thickness designation T3 and the M tolerance class ensure mechanical stability in the pocket and repeatable positioning, supporting consistent part quality across serial runs.

FAQ

What materials is this insert suitable for?
The CCMT09T308-MW4 WSM20S insert from Walter Tools is suitable for stainless steels (ISO group M) and heat‑resistant superalloys/titanium (ISO group S) thanks to its WSM20S grade and Tiger‑tec Silver coating.

How does the MW4 chipbreaker improve performance?
The MW4 chipbreaker promotes controlled chip formation and evacuation, which for the CCMT09T308-MW4 leads to fewer interruptions and steadier surface finishes when turning demanding alloys.

Can this insert handle interrupted cuts?
Yes — the 0.8 mm corner radius and robust geometry of the CCMT09T308-MW4 provide improved resistance to edge fracture, making it suitable for many interrupted turning applications within its material range.

What advantage does the Tiger‑tec Silver coating provide?
Tiger‑tec Silver enhances thermal resistance and preserves edge stability under high heat, extending tool life and supporting consistent cutting performance with the WSM20S grade.

Is the CCMT09T308-MW4 compatible with standard toolholders?
The insert follows common CCMT indexable insert dimensions and tolerances (tolerance class M), enabling use in compatible turning toolholders designed for rhombus 80° CCMT inserts.
