DNMG150604-NFT WSM20S indexable turning insert — Tiger·tec Silver, 0° negative rake (Walter Tools)

The DNMG150604-NFT WSM20S is an indexable turning insert in rhombic 55° form, engineered for heavy-duty finishing and medium-duty roughing on rostfreiem Stahl and heat‑resistant superalloys.

• Tiger·tec Silver coating for thermal stability
• Negative 0° rake for robust chip control
• Rhombic 55° shape with 0.4 mm corner radius
• Suited for stainless steels and superalloys

Stable cutting performance for demanding alloys

The combination of the WSM20S grade and the Tiger·tec Silver coating delivers improved thermal resistance and stable chip formation, which reduces the tendency for build‑up on the cutting edge when machining tough materials. The insert’s negative 0° rake provides a more durable cutting edge under interrupted or heavy cutting conditions; this geometry is particularly advantageous when machining stainless steels and heat‑resistant alloys where heat concentration and material ductility challenge tool life. The result is a dependable machining process with fewer interruptions.

Geometry that increases process security and surface quality

The rhombic 55° insert shape and 0.4 mm corner radius combine to offer a balanced profile between edge strength and achievable surface finish. Such a configuration enables secure clamping in standard turning holders and supports repeatable results across different part batches. The NFT chipbreaker is optimised for controlled chips in a range of feed rates, improving evacuation and reducing rework. Tolerance class M ensures consistent interchangeability and predictable performance in serial production.

Clear application guidance for workshop planning

Marked for ISO material groups M and S, this insert is intended for rostfreiem Stahl and heat‑resistant superalloys (including some titanium alloys), making it a practical choice for aerospace, energy and medical component machining where material heat input and chip behaviour must be managed. The indexable insert format allows quick seat changes and economical use of the cutting edges; selecting the correct holder and cutting data will further extend tool life and secure machining quality.

Operational advantages and shop-floor benefits

Using a coated solid‑carbide grade like WSM20S helps maintain a consistent cutting edge and reduces downtime from edge failures. Shops gain from improved process security and predictable performance, which supports planning and reduces scrap rates. The insert’s design supports both finishing and moderate roughing tasks, so fewer tool types may be required for mixed production runs — a practical benefit for job shops seeking efficient tool inventory management.

FAQ

What materials is this insert suitable for?
The DNMG150604-NFT WSM20S insert is designed for rostfreiem Stahl and heat‑resistant superalloys (ISO groups M and S), reflecting the WSM20S grade’s focus on thermal resistance and stable chip control.

How does the 0° negative rake affect machining?
A 0° (negative) rake increases edge strength and improves resistance to chipping under heavy or interrupted cuts; the DNMG150604-NFT WSM20S benefits from this geometry when used in robust turning operations.

Which chipbreaker is fitted and what is its benefit?
The insert features the NFT chipbreaker, which promotes controlled chip formation and evacuation across typical turning feeds, helping to maintain consistent surface quality and reduce handling of long chips.

Is this insert compatible with standard DNMG holders?
Yes, the DNMG150604-NFT form factor is compatible with standard holders for DNMG inserts; ensure proper clamping and the correct seat to achieve the specified tolerance class M and repeatable results.

What corner radius should be selected for finishing?
The supplied 0.4 mm corner radius on the DNMG150604-NFT WSM20S balances edge strength and surface finish; for finer finishes, select a smaller radius where the holder and process allow.
