DNMG150408-MM5 WSM10S turning insert (Tiger·tec Silver) by Walter Tools — 0° negative rake, 0.8 mm nose radius

The DNMG150408-MM5 WSM10S is a coated carbide turning insert designed for robust, repeatable machining of stainless steel and high‑temperature alloys, featuring a rhombic 55° form and an optimised MM5 chipbreaker for secure chip control

• Tiger·tec Silver coating for heat resistance and wear control
• MM5 chipbreaker for stable chip formation
• Negative 0° rake for robust cutting behaviour
• 0.8 mm nose radius for repeatable profiles

Increased process reliability through coating and grade performance

The combination of the Tiger·tec Silver coating and the WSM10S grade delivers higher thermal stability and improved edge life when machining difficult materials. Coating technology reduces adhesion and lowers thermal load at the cutting edge, which supports a stable cutting edge during longer cycles. For production environments this results in fewer tool changes and more predictable tool life, enhancing throughput and lowering downtime. The coated carbide substrate is optimised for materials that tend to work‑harden, so cutting data can be pushed safely while maintaining component quality.

Clear advantages in chip control and geometry for demanding materials

The insert’s MM5 chipbreaker geometry is engineered to promote predictable chip breakage and evacuation when turning stainless steel and heat‑resistant superalloys. Combined with the negative 0° rake, this geometry increases cutting edge strength and reduces the risk of build‑up, making the insert suitable for interrupted cuts and tougher workpiece conditions. The 0.8 mm nose radius gives a reliable surface finish and maintains dimensional repeatability across medium to heavy roughing passes, reducing the need for subsequent finishing in many workflows.

Application focus and recommended use cases

This insert is intended for operations where material behaviour and thermal stress challenge conventional grades — notably stainless steel and alloys covered by ISO groups S and M. The geometry and coating are particularly beneficial in turning operations that require a balance of edge stability and chip management, such as roughing followed by semi‑finishing of shafts and turned components. For new applications, it is recommended to validate cutting parameters on trial parts to determine optimal speeds and feeds; reference cutting data for the Tiger·tec Silver family can be requested for process planning.

FAQ

What materials is this insert suited for?
The DNMG150408-MM5 WSM10S insert is designed primarily for stainless steel and heat‑resistant alloys classified under ISO groups S and M.

How does the Tiger·tec Silver coating improve performance?
Tiger·tec Silver reduces thermal load and adhesion at the cutting edge, extending the edge life of the WSM10S grade and supporting more consistent machining results.

Which machining operations benefit most from this geometry?
Roughing and semi‑finishing operations with challenging chip control requirements gain the most, particularly where interrupted cuts or high temperatures occur.

Is the negative rake suitable for interrupted cuts?
Yes, the 0° negative rake increases edge strength and is well suited to interrupted cuts and heavy engagement conditions.

How does the MM5 chipbreaker affect surface finish?
The MM5 chipbreaker promotes reliable chip formation while the 0.8 mm nose radius helps achieve repeatable surface quality, often reducing the need for secondary finishing.
