CNMM120408-HU5 WMP20G — Turning insert, rhombic 80° with 0.8 mm nose radius, Walter Tools, for stainless steel

The CNMM120408-HU5 WMP20G is a rhombic turning insert engineered for stable, repeatable cutting of stainless steel in medium to robust applications; it combines a coated carbide grade with a dedicated chipformer to support secure chip control and extended edge life.

• Tiger·tec Gold coated carbide grade WMP20G
• Optimised chipformer HU5 for stable chip control
• Rhombic 80° insert with 0.8 mm nose radius
• Negative 0° relief angle for robust cutting

Reliable performance for stainless steel turning

The combination of the Tiger·tec Gold coating and the WMP20G carbide formulation gives the insert a balanced resistance to abrasion and built-up edge, which is essential when machining stainless steel, a material prone to toughness and heat generation. The coated microstructure reduces friction at the cutting zone and helps maintain a durable cutting edge, so cycle times remain consistent and downtime for tool changes is reduced. This leads to a measurable improvement in process stability and predictable component quality.

Consistent chip control and secure cutting conditions

Equipped with the HU5 chipformer, the indexable insert provides reliable chip segmentation and evacuation under a wide range of cutting parameters. The chipformer geometry is tailored for the ductile behaviour of stainless steels, supporting controllable chips that reduce the risk of entanglement and minimise surface damage. Combined with the negative 0° relief angle, the insert is suited to interrupted cuts and variable depths of cut, offering confidence in tougher production environments.

Geometry that supports accuracy and surface integrity

The rhombic 80° shape and 0.8 mm nose radius merge versatility and precision: the geometry allows adaptable cutting orientations while the nose radius balances strength and finish. For components where surface integrity matters, this geometry helps achieve consistent finish grades without compromising tool life. The insert’s form factor also facilitates predictable toolpath planning and straightforward index changes, contributing to overall machining efficiency.

Practical benefits for workshop productivity

Using this grade and geometry reduces the frequency of rework and stabilises cycle times, which positively affects throughput and cost per part. The insert’s characteristics make it a pragmatic choice for job shops and production lines that require both productivity and repeatability when machining stainless steel. Technical teams benefit from clearer machining windows, and production planners gain from the repeatable life and consistent edge performance of this grade.
