DNMG150404‑NFT WSM20S indexable turning insert by Walter Tools — Tiger‑tec Silver, negative rake 0°

The DNMG150404‑NFT WSM20S is a rhombic 55° indexable turn­ing insert designed for demanding work on stainless steels and heat‑resistant superalloys, offering a robust chipbreaker geometry for secure cutting.

• Tiger‑tec Silver coating for thermal resistance
• WSM20S grade for stainless and superalloys
• Rhombic 55° form with 0.4 mm corner radius
• Negative relief angle 0° for heavy cuts

High stability and consistent chip control for demanding materials

This insert’s combination of Tiger‑tec Silver coating and the WSM20S grade delivers improved thermal resistance and edge stability when machining stainless steel and heat‑resistant alloys. The NFT chipbreaker is engineered to promote stable chip formation, reducing the risk of built‑up edge and minimising process interruptions. For operations where consistent surface finish and predictable tool life are critical, the coated carbide chemistry and tailored geometry reduce wear rates and help secure repeatable results.

Geometry and design that increase productivity and reduce setup time

The rhombic 55° shape with a 0.4 mm corner radius and a negative relief angle (0°) allows for robust engagement in turning applications, especially where interrupted cuts or heavy machining are present. The insert form supports versatile approach angles while maintaining a reliable cutting edge, which can shorten cycle times and lower the frequency of tool changes. By selecting a dedicated grade and chipbreaker, production planners gain measurable advantages in throughput and process reliability.

Application guidance and practical advantages on the shop floor

Specified for workpiece groups S and M (heat‑resistant superalloys/titanium and stainless steel), the insert performs where heat generation and material toughness challenge conventional grades. In practice, this means fewer rejects, improved edge retention and more predictable maintenance intervals. When paired with appropriate cutting data and a stable clamping system, the insert contributes to lower overall machining costs through longer cutting lengths per edge and reduced regrinding needs.

FAQ

What materials is this insert suitable for?
The DNMG150404‑NFT WSM20S from Walter Tools is formulated for stainless steel (M) and heat‑resistant superalloys/titanium (S), providing reliable cutting performance where high temperatures and toughness occur.

How does the Tiger‑tec Silver coating improve performance?
Tiger‑tec Silver increases thermal resistance and reduces wear on the cutting edge, allowing the WSM20S grade to maintain stability and cutting efficiency under elevated temperatures and demanding conditions.

Why choose a negative relief angle of 0°?
A 0° (negative) relief angle offers stronger cutting edges suitable for heavy cuts and interrupted machining, improving edge life and reducing the likelihood of chipping during roughing operations.

What is the benefit of the NFT chipbreaker?
The NFT chipbreaker promotes controlled chip formation and evacuation, which supports consistent surface finish and reduces the chance of built‑up edge when machining tough or adhesive materials.

Is this an original Walter Tools product and how is authenticity ensured?
The item is an original, brand‑new insert from Walter Tools, supplied under the SKU DNMG150404‑NFT‑WSM20S‑WALTER and intended for professional machining applications.
