DNMG150608‑NRS WMP20S indexable turning insert — for rostfreier Stahl, Tiger‑tec Silver, Walter Tools

The DNMG150608‑NRS WMP20S is a rhombic 55° indexable turning insert engineered for medium to robust machining of rostfreier Stahl, offering controlled chip formation and enhanced edge stability.

• Tiger‑tec Silver coated carbide grade
• For rostfreier Stahl (ISO M) machining
• Rhombic 55° form with 0.8 mm corner radius
• 0° negative rake for stable cutting

High process reliability when machining rostfreier Stahl

The coated WMP20S grade, part of the Tiger‑tec Silver series, is designed specifically for the challenges of machining rostfreier Stahl. The combination of a modern PVD/CVD-style coating and a wear-resistant carbide substrate improves temperature resistance and reduces built-up edge formation, which results in fewer interruptions and a steadier surface finish. This tailored material pairing enables a predictable tool life under medium to demanding cutting conditions and reduces the frequency of insert changes in serial production.

Predictable chip control and extended edge life

The NRS chipbreaker is matched to the insert geometry to promote short, manageable chips when turning tough, adhesive materials. Stable chip formation reduces toolface adhesion and lowers the risk of damage to the cutting edge, which in turn maintains dimensional accuracy over longer cycles. By favouring consistent chip evacuation, workshops can achieve improved cycle times and reduced rework—an advantage for repetitive turning operations where repeatability is crucial.

Geometry engineered for stability and accessibility

The rhombic 55° form provides a versatile cutting angle that balances approachability in confined toolposts with a robust cutting edge capable of handling interrupted cuts. The 0.8 mm corner radius supports a stronger edge profile for heavier feed applications while preserving surface quality. The 0° (negative) rake contributes to a durable cutting geometry that resists chipping under higher radial loads, making this insert suitable for turning tasks that demand both strength and reliability.

Practical application and toolholder compatibility

Marked as DNMG150608‑NRS, the insert follows common ISO sizing for straightforward integration into existing toolholders and turret systems. The thickness code and size enable stable clamping and repeatable indexability. As a product from Walter Tools, this insert suits production environments that prioritise continuous throughput and consistent component tolerances, particularly where rostfreier Stahl properties—like toughness and heat sensitivity—require a specialised cutting solution.

FAQ

What materials is this insert suitable for?
The DNMG150608‑NRS WMP20S is specified for machining rostfreier Stahl (ISO M) and performs reliably under medium to robust cutting conditions.

How does the Tiger‑tec Silver coating benefit cutting performance?
The Tiger‑tec Silver coating on the WMP20S grade increases temperature resistance and reduces adhesion, which helps to stabilise the cutting edge and extend the insert's operational life.

Is the insert compatible with standard DNMG toolholders?
Yes, the DNMG150608‑NRS form follows ISO DNMG sizing and fits standard DNMG toolholders designed for rhombic 55° inserts.

What cutting conditions suit the 0° negative rake geometry?
A 0° negative rake provides a robust cutting edge for higher radial loads and interrupted cuts, making the insert suitable for demanding turning operations where edge strength is essential.
