DNMG150408-MU5 WSM20S turning insert, Tiger·tec Silver for stainless steels — Walter Tools

The DNMG150408-MU5 WSM20S is a coated indexable insert engineered for stable metalcutting in rostfreiem Stahl and heat‑resistant superalloys, offering a robust chipbreaker and a neutral clearance for heavy and interrupted cuts.

• Tiger·tec Silver coating for edge stability
• Optimised MU5 chipbreaker for secure chip control
• 0° negative clearance for robust cutting
• Suitable for stainless steel and superalloys

Greater productivity on tough-to-machine alloys

The Tiger·tec Silver series with the WSM20S grade delivers a balance of wear resistance and thermal stability that reduces unscheduled tool changes. The coated carbide substrate and surface treatment improve edge life under the high temperatures typical when machining stainless steels and heat‑resistant alloys. In practice, this means longer periods between indexings and more predictable cycle times, which supports efficient throughput and lower per‑part tooling cost. The design targets turning operations where secure chip formation and sustained cutting forces are decisive for process reliability.

Stable geometry for consistent surface quality

The rhombic 55° format paired with a 0° negative clearance and a 0.8 mm corner radius provides mechanical strength at the cutting edge and resistance to chipping during heavier feed or interrupted cuts. The MU5 chipbreaker is optimised to form compact, controllable chips on demanding materials, reducing entanglement and improving surface finish. These geometric choices favour high metal removal rates while maintaining dimensional repeatability, making the insert suitable for both roughing and mixed finishing tasks where edge robustness is more important than minimal cutting forces.

Practical integration and production benefits

The DNMG form factor is widely supported by standard toolholders, enabling straightforward retrofitting into existing tool assemblies. With a clear tolerance class M and the Tiger·tec Silver coating, the insert supports reproducible tool setups and stable process windows. For production environments focused on rostfreiem Stahl and superalloys, the combination of a dependable chipbreaker and a coated grade designed for heat resistance helps to lower cycle interruptions and improve shopfloor uptime. For bespoke cutting parameters or verification of toolholder fitment, technical consultation is advised to match feeds, speeds and depth of cut to the specific workpiece and machine capability.

FAQ

What materials is this insert suitable for?
The DNMG150408-MU5 WSM20S is formulated for stainless steels and, depending on geometry, for heat‑resistant superalloys and titanium, reflecting the WSM20S grade’s focus on thermal stability and edge durability.

What is the benefit of the MU5 chipbreaker?
The MU5 chipbreaker provides controlled, compact chip formation on demanding alloys, improving chip evacuation and reducing the risk of chip re‑cutting, which helps maintain surface quality and tool life with the WSM20S grade.

What does a 0° negative clearance imply for machining?
A 0° negative clearance gives the insert a more robust support of the cutting edge, which increases resistance to chipping and is advantageous in heavier or interrupted cuts where edge strength is prioritised.

Can this insert be used for finishing operations?
Yes; while the geometry favours robustness, the 0.8 mm corner radius and the coated grade allow for mixed roughing‑to‑finishing applications provided appropriate feeds and speeds are selected.

Is the DNMG format compatible with standard toolholders?
The DNMG designation corresponds to a common insert family; the DNMG150408‑form fits standard DNMG holders but verification of seat size and clamping style is recommended before assembly.
