CNMG120408-MU5 WMP20G — Turning insert (Rhombus 80°, 0° negative), Walter Tools

The CNMG120408-MU5 WMP20G is a rhombic 80° indexable turning insert designed for robust machining of rostfreier Stahl under medium to heavy conditions.

• Tiger·tec Gold coated carbide grade
• MU5 chipbreaker for reliable chip control
• 0° negative rake for heavy-duty turning
• 0.8 mm corner radius for edge strength

Consistent performance on rostfreier Stahl for improved cycle times

The Tiger·tec Gold coating and the WMP20G grade deliver a balanced performance specifically tuned for rostfreier Stahl, a group of alloys prone to built-up edge and high heat. By combining a wear-resistant PVD/CVD-style coating with a substrate optimised for toughness, this insert supports stable cutting edges and reduced flank wear over extended cycles. The result is fewer interruptions for tool change and more predictable component quality, which translates directly into improved process throughput and reproducible surface finish.

Secure chip control and edge integrity with MU5 geometry

The MU5 chipbreaker is engineered to produce short, controllable chips when turning challenging stainless alloys; this lowers the risk of entanglement and facilitates safe, automated operation. In conjunction with the 0° (negative) rake geometry, the insert offers a secure cutting action and resistance to thermal shock during interrupted cuts. The 0.8 mm corner radius increases the edge strength, allowing slightly higher depths of cut without compromising the insert life—an advantage for shops aiming for steady material removal rates while preserving dimensional accuracy.

Practical benefits for workshop integration and process reliability

As a rhombic 80° insert with a compact profile, this solution fits a broad range of standard CNMG toolholders and supports both finishing and roughing steps in a streamlined tool set. The coated cemented carbide composition and the Tiger·tec Gold technology help to extend tooling intervals and reduce overall tooling costs per part. For production planners, the combination of wear resistance and chip control means fewer unplanned stops and a simpler inventory of grades for rostfreie Stähle, making process planning and quality assurance more straightforward.
