DCMT070204-MM4 WSM30S rhombic 55° turning insert — Tiger·tec Silver, MM4 chipbreaker (Walter Tools)

A DCMT070204-MM4 WSM30S indexable turning insert engineered for productive machining of rostfreier Stahl and heat‑resistant superalloys, offering a robust coated‑carbide grade within the Tiger·tec Silver series

• Tiger·tec Silver coated carbide grade WSM30S
• Optimised MM4 chipbreaker for stable chips
• Suited to rostfreier Stahl and heat‑resistant alloys
• Rhombic 55° insert with 0.4 mm corner radius

High productivity for hard‑to‑cut materials

The combination of a coated carbide grade from the Tiger·tec Silver family and an MM4 chipbreaker delivers consistent cutting performance when machining rostfreier Stahl and nickel‑base alloys. The coating improves heat resistance and reduces flank wear, which means longer tool life and fewer indexings on the turret. For practical production, this translates into fewer stoppages and a more predictable tool‑change schedule, supporting higher throughput without sacrificing component quality.

Precise chip control and surface reliability

With a dedicated chipbreaker geometry, the insert produces short, controllable chips under typical turning conditions, reducing the risk of chip entanglement and workpiece damage. The rhombic 55° form and 0.4 mm corner radius improve the engagement and create a reliable cutting edge for stable feeding; as a result, the insert enables improved surface finish and dimensional repeatability even in challenging feeds. The geometry is particularly beneficial where secure chip evacuation is required to maintain cycle times and machine availability.

Robust design that supports consistent process results

Tolerance class M and a relief angle of 7° provide a balanced compromise between edge strength and cutting access in shoulder and profiling operations. The insert is optimised for applications where heat generation and built‑up edge formation are common; by using a dedicated grade and coating technology, the cutting edge retains integrity under higher cutting temperatures, supporting repeatable quality across batches. This design focus reduces rework rates and contributes to a predictable manufacturing process.

Practical benefits for workshop integration

As a compact, indexable solution, the insert simplifies stocking and tool management: the standard ISO designation and common size format make integration into existing toolholders straightforward. Reduced downtime from longer tool life and stable chip formation improves overall equipment effectiveness (OEE). For teams aiming to increase productivity while maintaining component quality, the insert provides a technically sound and economically sensible option that aligns with modern machining requirements.
