DCGT070204-MM4 WSM20S turning insert — Tiger·tec Silver grade for rostfreier Stahl and superalloys | Walter Tools

The DCGT070204-MM4 WSM20S is a rhombic 55° turning insert designed for demanding applications on rostfreier Stahl and heat‑resistant superalloys, offering a balance of edge stability and secure chip formation.

• Tiger·tec Silver coating, WSM20S grade
• Optimised for rostfreier Stahl and superalloys
• Rhombic 55° geometry with 7° clearance
• MM4 chipbreaker for consistent chip control

Increase throughput on difficult-to-machine alloys with proven coating technology

The combination of Tiger·tec Silver and the WSM20S grade provides high thermal and abrasive resistance, which directly translates into longer tool life and fewer interruptions. For materials that tend to work‑harden or generate heat, such as rostfreier Stahl and nickel‑based superalloys, the coated carbide supports stable chip formation and reduces the risk of built‑up edge. This increases process reliability and can lower overall machining costs by reducing tool change frequency and scrap rates. The design focus is on delivering measurable productivity gains rather than abstract promises.

Consistent surface quality and durable cutting edge through geometry and chip control

The insert's MM4 chipbreaker, combined with a 0.4 mm corner radius and rhombic 55° form, yields reproducible chips and a controlled contact zone at the cutting edge. A 7° clearance minimises flank rubbing while maintaining cutting security, which benefits surface finish and dimensional stability on delicate components. The result is a predictable machining outcome: fewer reworks and a smaller spread in surface roughness values. Where finish matters, the geometry supports a fine balance between robustness and detail.

Simple integration into established tool rooms and clear specification for process planning

Marked as DCGT070204-MM4, the insert follows common industry designation practices and fits into compatible clamping systems for rhombic turning plates. The tolerance class G supports repeatable indexing and positional accuracy during insert changes. Material suitability is stated as S / M, indicating the insert's intended use for Titan/high‑temperature alloys and rostfreier Stahl according to ISO classifications; this helps with quick process selection and tooling standardisation. For shops standardising setups, the plate thickness and format aid straightforward procurement and inventory management while contributing to stable cycle times.

FAQ

What materials is this insert best suited for? The DCGT070204-MM4 WSM20S insert is optimised for rostfreier Stahl and heat‑resistant superalloys, offering secure chip formation and thermal resistance for these groups.

How does the MM4 chipbreaker affect machining? The MM4 chipbreaker on the DCGT070204-MM4 promotes consistent chip control and reduces the tendency for long, stringy chips, improving process safety and surface finish.

What benefits does the Tiger·tec Silver coating provide? Tiger·tec Silver increases wear and heat resistance on the cutting edge of the DCGT070204-MM4, resulting in longer tool life and fewer change‑overs under demanding cutting conditions.

Is the insert suitable for precision turning operations? Yes; the tolerance class G and the rhombic 55° geometry support repeatable indexing and stable cutting, which is beneficial for precision turning tasks.

How does the 0.4 mm corner radius influence results? A 0.4 mm corner radius offers a compromise between edge strength and achievable surface finish, giving the DCGT070204-MM4 resilience against chipping while still allowing fine tolerances.
