DNMG150608-NRS WSM20S Drehwendeschneidplatte – Tiger·tec Silver, for rostfreier Stahl (Walter Tools)

DNMG150608-NRS WSM20S is a rhombic 55° indexable turning insert designed for demanding turning operations on rostfreier Stahl and heat-resistant superalloys

*Tiger·tec Silver coating for thermal stability
*NRS chipbreaker for controlled chips
*Rhombic 55° form for versatile turning
*Corner radius 0.8 mm for edge strength

High thermal stability for heavy-duty turning

The insert combines the WSM20S grade with the Tiger·tec Silver coating to deliver higher heat resistance and improved cutting-edge life when machining demanding alloys. Coating technology reduces thermal load on the cutting edge and helps maintain dimensional stability under continuous cutting. This leads to more predictable tool life and fewer interruptions for tool change, which supports a smoother production flow and reduced overall machining costs.

Geometry engineered for stable cutting and chip control

A rhombic 55° profile and a negative 0° rake produce a strong cutting edge that resists chipping during interrupted cuts and heavy engagement. The integrated NRS chipbreaker promotes short, stable chips when processing sticky, work-hardening materials, improving surface finish and machine safety. The 0.8 mm corner radius increases edge robustness and reduces the risk of premature flank wear, which is particularly valuable on long production runs.

Suitability for rostfreier Stahl and high-temperature alloys

The grade is certified for ISO material groups M and S, meaning it is optimised for rostfreier Stahl as well as heat-resistant superalloys and titanium. These materials tend to generate high temperatures and adverse chip behaviour; the grade’s balanced microstructure and coating address these challenges by supporting consistent chip formation and a stable cutting edge. As a result, machining processes become more reliable and repeatable across batches.

Practical benefits for process reliability

Tolerance class M and the standard insert dimensions (inscribed circle 15, thickness 06) make the insert compatible with common toolholders and replacement cycles, helping to simplify inventory management. The combination of grade, coating and geometry reduces the frequency of rework and supports a higher first-pass yield. For shops aiming to increase throughput on rostfreier Stahl components, the insert offers measurable gains in tool life and surface quality without compromising process security.

Guidance and support for specification choices

For questions about selecting the correct insert geometry or optimising cutting data for specific rostfreier Stahl grades or superalloys, technical consultation is available. Technical experts can advise on adapting speeds, feeds and coolant strategies to exploit the Tiger·tec Silver advantages and the NRS chipbreaking design for the best balance of productivity and tool life.

FAQ

What materials is this insert best suited for?
The DNMG150608-NRS WSM20S insert is designed for rostfreier Stahl (ISO group M) and heat-resistant superalloys or titanium (ISO group S), offering stable chip formation and heat resistance.

How does the Tiger·tec Silver coating benefit machining?
The Tiger·tec Silver coating on this Walter Tools grade improves thermal stability and wear resistance, which prolongs effective cutting life under elevated cutting temperatures.

What advantage does the NRS chipbreaker provide?
The NRS chipbreaker is engineered to produce controlled, short chips in sticky or work-hardening materials, enhancing surface finish and reducing the risk of entangling long chips.

Is the negative 0° rake suitable for interrupted cuts?
Yes, the negative 0° free angle increases cutting-edge strength, making the insert more tolerant of interrupted cuts and heavy radial engagement.

Which insert geometry should be matched with this plate?
Use holders compatible with a rhombic 55° insert form and the specified plate size and thickness; this ensures secure clamping and correct cutting-geometry alignment for process reliability.
