CNMM120412-HU5 WMP20G turning insert for rostfreier Stahl by Walter Tools

The CNMM120412-HU5 WMP20G is a negative-rake, rhombic 80° turning insert engineered for dependable machining of rostfreier Stahl under medium to robust cutting conditions.

• Tiger·tec Gold coating for long tool life
• HU5 chipbreaker for reliable chip control
• Rhombic 80° shape for versatile turning
• Designed for rostfreier Stahl machining

Consistent cutting performance through advanced coating technology

The Tiger·tec Gold coating combined with the WMP20G grade provides improved thermal stability and wear resistance, which translates into longer edge life and fewer interruptions on the shopfloor. For production environments machining rostfreier Stahl, this results in higher overall tool utilisation and a lower cost per component; the coated cemented carbide base helps to counteract adhesive wear and supports stable chip formation under elevated temperatures. These technical properties make the insert suitable where repeatability and predictable tool life are required.

Stable chip control and surface quality with HU5 geometry

The dedicated HU5 chipbreaker, together with the rhombic 80° profile and negative rake 0°, promotes controlled chip segmentation and reduces the risk of built-up edge formation. That combination improves surface finish and reduces the need for secondary operations. The moderate corner radius (1.2 mm) balances edge strength with the ability to achieve good finishes on external and light profiling cuts. In practice, this means fewer machine stops for clearing chips and less rework, supporting smoother production flow and measurable efficiency gains.

Versatile insert geometry for flexible turning applications

The CNMM120412-HU5 format offers a pragmatic mix of rigidity and accessibility: the insert size and thickness 04 support stable cutting at a range of feeds and depths of cut, while the 1.2 mm nose radius enables reliable edge strength for interrupted or continuous cuts. The insert is suitable for integration into standard toolholders for CNMM-geometry inserts and adapts well to mixed-batch and series production in metalworking shops that process rostfreier Stahl. Its specification supports both finishing and light roughing tasks when paired with appropriate cutting data.
