CNMG120408-NRS WSM10 Drehwendeschneidplatte – turning indexable insert by Walter Tools, rhombic 80°, negative 0° relief

The CNMG120408-NRS WSM10 is a robust turning indexable insert designed for machining stainless steel and heat‑resistant alloys, offering a coated carbide grade for improved chip control and edge life.

• Coated carbide grade WSM10 for tough materials
• Rhombic 80° shape for secure clamping
• 0.8 mm corner radius for edge durability
• Negative 0° relief for heavy, interrupted cuts

Increased throughput when machining stainless steel and superalloys

The WSM10 coated carbide grade is formulated for demanding applications involving stainless steel and heat‑resistant superalloys. Its coating improves thermal resistance and supports stable chip formation, which reduces rework and downtime. For production environments that require predictable component quality, this insert delivers consistent cutting performance; the result is fewer tool changes and a more efficient machining cycle. The design targets the most common failure modes when cutting tough materials and therefore increases process reliability.

Geometry engineered for edge strength and process security

The rhombic 80° insert form with a 0.8 mm corner radius and negative 0° relief provides mechanical robustness for interrupted and heavily loaded cuts. The combination of these geometry elements allows for improved force distribution at the cutting edge, reducing chipping and flank wear. As a consequence, the tool maintains dimensional stability over longer tool life, supporting repeatable surface finish and tolerances in batch production. This geometry is particularly advantageous where component integrity matters and tool change intervals must be minimised.

Predictable chip control and straightforward integration

Equipped with the NRS chipbreaker, the insert facilitates controlled chip formation across a range of cutting conditions, which helps avoid entangling chips and protects both the workpiece and the machine. The insert follows standard CNMG interfaces, ensuring compatibility with common toolholders and clamping systems. With a tolerance class of M and a 4 mm plate thickness code, the part integrates into existing setups without alteration of tool posts. This predictability reduces set‑up time and aids quick process validation in serial production.
