CNMG120412-FM5 WSM20S indexable turning insert — Tiger·tec Silver for stainless steel / high‑temperature alloys (Walter Tools)

The CNMG120412-FM5 WSM20S is a rhombic 80° indexable turning insert designed for heavy and demanding turning applications in stainless steel and heat‑resistant superalloys.

• Tiger·tec Silver coating technology
• Grade WSM20S for thermal stability
• FM5 chipbreaker for controlled chips
• Rhombic 80° with 1.2 mm corner radius

Increased process reliability through advanced coating and grade

The combination of the Tiger·tec Silver coating and the WSM20S carbide grade delivers higher resistance to heat and abrasion during challenging turning operations. This engineered pairing reduces flank wear and supports a stable cutting edge, which in practice means fewer tool changes and longer uninterrupted cycles. The result is measurable process stability: consistent tool life helps to lower unexpected downtime and supports predictable manufacturing output in serial production.

Predictable chip formation and consistent surface quality

The FM5 chipbreaker, together with the rhombic 80° form and corner radius 1.2 mm, promotes controlled chip segmentation, minimises the risk of built‑up edge and improves the surface finish on stainless steel and S‑group alloys. The 0° negative rake geometry is suited to robust cutting conditions where edge security and repeatability are priorities. In plain terms, the chipbreaker directs chips away from the cutting zone, which reduces rework and contributes to stable cycle times on both continuous and interrupted cuts.

Practical selection for demanding turning tasks and straightforward logistics

The insert designation CNMG120412-FM5 WSM20S identifies size, geometry and chip control clearly, simplifying tool selection for production planning and inventory management. Tolerance class M and the standardised rhombic form mean compatibility with commonly used CNMG toolholders, easing logistics and replacement. Backed by Walter Tools’ reputation for precision tooling, the insert suits workshops aiming for reproducible results on stainless steel and heat‑resistant materials while keeping setup and maintenance effort low.

FAQ

Which materials is this insert intended for?
The CNMG120412-FM5 WSM20S insert is specified for stainless steel and for heat‑resistant superalloys/titanium (material groups M and S).

What advantage does the FM5 chipbreaker provide?
The FM5 chipbreaker on this insert promotes reliable chip segmentation, directing chips away from the cutting zone and supporting consistent surface quality during turning.

What are the key geometry details to consider?
The insert features a rhombic 80° form, a corner radius of 1.2 mm and a 0° negative rake, which together favour edge security and repeatable cutting performance under heavy conditions.

Is this insert compatible with standard CNMG toolholders?
The CNMG120412-FM5 designation corresponds to common CNMG toolholder interfaces and is suitable for standard indexable turning tool systems that accept CNMG inserts.

How does the Tiger·tec Silver series benefit production runs?
Tiger·tec Silver coating enhances thermal and abrasive resistance, which contributes to longer tool life and reduced frequency of insert changes in high‑temperature or sticky material applications.
