DNMG110408-FW5 WSM20S turning insert — Tiger·tec Silver, FW5 chipbreaker (Walter Tools)

A DNMG110408-FW5 WSM20S indexable turning insert engineered for secure machining of rostfreier Stahl and heat‑resistant superalloys, offering a rhombic 55° geometry and FW5 chip control.

• Tiger·tec Silver coating WSM20S
• For rostfreier Stahl and superalloys
• Rhombic 55° geometry, 0.8 mm corner radius
• FW5 chipbreaker for secure chip control

Predictable cutting performance for demanding materials

The insert delivers consistent edge life through a combination of a coated carbide substrate and the WSM20S grade, which is formulated for high thermal and mechanical loads. The FW5 chipbreaker stabilises chip flow, reducing the risk of built‑up edge and facilitating uninterrupted turning cycles; this leads to fewer interruptions and improved machine utilisation. The 0° negative rake supports robust engagement in heavy cuts, while the rhombic 55° form provides low‑interference access to both external and face turning operations.

Coating and grade engineered for heat and adhesion resistance

The Tiger·tec Silver coating technology enhances heat resistance and wear protection, which is particularly beneficial when machining rostfreier Stahl and materials in ISO group S (heat‑resistant superalloys and titanium). The WSM20S grade is a coated carbide designed to maintain a stable cutting edge under high temperatures and to support controlled chip formation. The insert’s 0.8 mm corner radius balances edge strength with surface finish, making it suitable for components where edge robustness and dimensional consistency are required.

Process security and integration into machining cells

Produced to tolerance class M, the insert supports repeatable clamping and predictable geometry across production batches. The part designation is optimised for standard toolholders that accept DNMG‑style plates, allowing straightforward integration into existing tool libraries. For applications requiring high process reliability, the combination of chip control, coating technology and geometry reduces scrap rates and improves overall throughput; basic setup parameters and cutting data are selectable according to workpiece material and operation type to achieve reproducible results.

FAQ

What materials is this insert suitable for?
The DNMG110408‑FW5 WSM20S insert is designed for rostfreier Stahl (ISO group M) and heat‑resistant superalloys/titanium (ISO group S) due to the thermal stability of the WSM20S grade.

How does the FW5 chipbreaker affect machining?
The FW5 chipbreaker promotes controlled chip formation and secure evacuation, which reduces the risk of built‑up edge and enhances process stability for continuous turning operations.

What is the purpose of the 0° negative rake?
The 0° negative rake increases cutting edge robustness for interrupted or heavy cuts, providing improved resistance to mechanical and thermal shock during demanding operations.

Can this insert be used in standard DNMG toolholders?
Yes, the insert follows DNMG geometry and is compatible with toolholders designed for DNMG‑style indexable plates, enabling straightforward replacement and integration.

What advantage does the Tiger·tec Silver coating provide?
The Tiger·tec Silver coating increases thermal resistance and wear protection, extending edge life and maintaining consistent surface finish when machining hard or heat‑generating materials.
