SNMG120408-RM5 WMP30G — square turning insert, Tiger·tec Gold coating (stainless steel) | Walter Tools

The SNMG120408-RM5 WMP30G is a square indexable turning insert engineered for robust machining of stainless steel; the negative 0° relief and RM5 chipbreaker support secure chip formation in demanding conditions.

• Tiger·tec Gold coated cemented carbide
• Optimised for stainless steel machining
• 0.8 mm corner radius for durable edges
• RM5 chipbreaker for stable chip control

Consistent performance for stainless steel under load

The combination of the WMP30G grade and Tiger·tec Gold coating delivers a resistance to abrasive wear and thermal stress that suits the demanding characteristics of stainless steel. The coated cemented carbide substrate supports stable cutting edges and reduces the tendency for built-up edge, which in turn improves process reliability. This results in fewer unplanned tool changes and a more predictable production flow for serial and batch turning operations.

Geometry designed for edge strength and predictable finishes

A square 90° insert form with a 0° (negative) relief angle provides mechanical robustness for interrupted cuts and heavier feed conditions. The 0.8 mm corner radius increases edge strength while still allowing acceptable surface quality on workpieces. The RM5 chipbreaker is optimised to produce compact, controllable chips in stainless steel, helping to avoid entanglement and to improve machine uptime. These features together create a balance between durability and component finish.

Better chip control and production security

Chip management is central to efficient turning. The RM5 geometry promotes reproducible chip breaking and evacuation, reducing machine downtime and guarding against surface damage. The coated grade WMP30G supports this by maintaining a stable cutting edge under thermal and mechanical loads. In production environments where repeatability and process security are priorities, the insert’s construction contributes to lower tooling costs per component through extended service intervals and consistent component quality.

Practical selection and integration into toolholders

The insert’s SNMG120408-RM5 format (size 12, thickness code 04) fits industry-standard square turning toolholders designed for this ISO geometry. Selection should consider the intended feed, depth of cut and the specific stainless steel grade to be machined; matching the RM5 chipbreaker and the WMP30G grade to the application supports optimum cycle times and tool life. For application-specific set-up, tooling systems and assembly recommendations, the manufacturer’s guidance and distributor consultancy can assist in achieving a stable cutting process.
