Consistent performance on stainless steel

The combination of the WMP20G grade and Tiger·tec Gold coating supports reliable metal removal when working with stainless steel, materials that tend to be tough and prone to built-up edge. The coated-carbide substrate offers improved edge stability, which reduces unplanned tool changes and increases process uptime. With a focus on measurable production benefits, this solution helps to maintain consistent surface quality while lowering the risk of premature flank wear.

Geometry and edge design that improve productivity

The rhombic 80° plate form and a corner radius of r = 1.6 mm provide a balance between strength and form accuracy. The insert’s 0° negative rake increases edge robustness on interrupted cuts and heavy feeds, while the HU5 chipbreaker keeps chips compact and manageable. For shop-floor planning, the stronger cutting edge means fewer tool rotations and predictable cycle times, translating directly into higher throughput and less operator intervention.

Practical selection and integration guidance

Designed to fit standard CNMM toolholders, this insert simplifies tooling logistics and replacement. The coated carbide grade is intended for medium to robust conditions on stainless steel; match feed and speed to the material condition and machine rigidity for best results. For businesses aiming to standardise on a single grade for stainless applications, the Tiger·tec Gold family offers broad applicability and repeatable performance. If further optimisation or verification is required, Metav Werkzeuge can provide targeted advice on insert geometry and machining parameters.

FAQ

Which materials is this insert designed for?
This insert is specified for stainless steel (stainless steels) and is optimised for the typical demands of these materials using the Walter Tools WMP20G grade.

What does the HU5 chipbreaker deliver in practice?
The HU5 chipbreaker produces short, controllable chips and supports stable cutting under medium to robust conditions, improving process safety and surface consistency.

What are the key geometry values to consider for setup?
Key values are the rhombic 80° form, r = 1.6 mm corner radius and a 0° negative rake; these influence feed selection, depth of cut and holder rigidity requirements.

Can this insert be used in standard CNMM holders?
Yes; the CNMM160616-HU5 designation corresponds to standard CNMM toolholders, allowing straightforward integration into existing turning toolsets.

What advantages does the Tiger·tec Gold coating provide?
Tiger·tec Gold promotes a stable cutting edge and extended tool life on stainless steel, reducing wear and enabling consistent results over longer tool lifetimes.
