DCMT070204‑FW4 WSM30S – Indexable turning insert, Tiger‑tec Silver for stainless steels and superalloys (Walter Tools)

DCMT070204‑FW4 WSM30S is an indexable turning insert engineered for demanding turning operations on stainless steels and heat‑resistant superalloys, offering reliable edge stability and efficient chip control.

• Tiger‑tec Silver coating for high wear resistance
• Optimised FW4 chipbreaker for secure chip control
• Rhombic 55° DCMT geometry for versatile turning
• 0.4 mm corner radius with 7° clearance angle

Higher productivity through heat‑resistant coating and stable cutting edges

The insert's Tiger‑tec Silver coating and the WSM30S substrate work together to resist thermal degradation and abrasive wear when machining tough materials. This results in a more consistent cutting edge over longer cycles and fewer tool changes, which translates directly into higher process throughput. The advanced coating also reduces the tendency for built‑up edge on stainless steels, supporting improved dimensional stability and surface quality in serial production.

Safer chip formation reduces interruptions and rework

Equipped with the FW4 chipbreaker, the geometry promotes predictable chip formation and evacuation in sticky or heat‑prone materials. Predictable chips minimise risk to the workpiece and the machine, help maintain coolant effectiveness and reduce component cleaning or rework. The practical outcome is less unplanned downtime and a steadier production rhythm for batches that require repeatable surface finish and tolerance control.

Geometry designed for flexibility and repeatability

The rhombic 55° DCMT shape combined with a 0.4 mm corner radius and 7° clearance angle provides a balance between edge strength and accessibility for a range of turning tasks. The insert format allows multiple indexing positions, offering economical use of each insert while ensuring repeatable seating and cutting behaviour. For workshops processing diverse stainless grades and Ni‑base alloys, this geometry supports both roughing passes with secure edge life and finishing cuts with consistent surface results.

Application suitability and process guidance

Rated for the ISO material groups M and S, the grade targets stainless steels (M) and heat‑resistant superalloys / titanium (S). Selection of cutting data should favour moderate to elevated speeds with attention to feed and coolant strategy to exploit the coating's heat resistance. Using the DCMT070204‑FW4 WSM30S in well‑matched holder geometries enhances process security and reduces variability across components, delivering economic gains through longer tool life and fewer machine stoppages.

FAQ

What materials is this insert best suited for?
The DCMT070204‑FW4 WSM30S is designed primarily for stainless steels and heat‑resistant superalloys (ISO groups M and S), where the Tiger‑tec Silver grade improves thermal stability and edge life.

How does the FW4 chipbreaker benefit production?
The FW4 chipbreaker on the DCMT070204‑FW4 promotes predictable chip formation and evacuation, which reduces interruptions and supports a consistent surface finish on challenging materials.

Can the insert be used for both roughing and finishing?
Yes; the rhombic 55° geometry and a 0.4 mm corner radius make the insert versatile enough for heavier cuts as well as fine finishing passes when correct cutting data are applied.

How does the Tiger‑tec Silver coating affect tool life?
The Tiger‑tec Silver coating enhances wear resistance and reduces thermal damage to the cutting edge, extending effective tool life in demanding machining of stainless steels and superalloys.

What benefits does the DCMT format provide in indexable tooling systems?
The DCMT format offers multiple indexable edges per insert, straightforward mounting and repeatable seating, ensuring cost‑efficient use of the insert and stable performance across production runs.
