SNMG120408-RM5 WMP20S — Turning insert (Tiger·tec Silver) by Walter Tools

SNMG120408-RM5 WMP20S is a robust indexable turning insert designed for medium to heavy duty machining of rostfreier Stahl under demanding conditions

• Tiger·tec Silver coating for durability
• Optimised RM5 chipbreaker for secure chip control
• Square 90° form with 0.8 mm corner radius
• Suitable for rostfreier Stahl applications

Durable coating for longer tool life and consistent edges

The combination of the Tiger·tec Silver coating and the WMP20S carbide grade provides a wear-resistant cutting edge that is especially advantageous when machining rostfreier Stahl. Coated carbide reduces flank wear and preserves the cutting geometry over longer intervals, which translates into fewer insert changes and more predictable production cycles. The coating also supports temperature resistance under higher cutting loads, ensuring that the edge remains stable during interrupted cuts or when heat accumulation occurs. This performance characteristic reduces process variation and supports higher overall machine utilisation.

Geometry engineered for secure chip formation and surface quality

The insert’s RM5 chipbreaker and Square 90° form work together to control chip flow and protect the cutting edge. The 0° negative rake increases edge robustness for tougher cuts, while the 0.8 mm corner radius balances strength with the ability to achieve acceptable surface finishes. For workshops that require repeatable turning results, these geometry features deliver controlled chip breaking and reduced risk of built-up edge, helping to lower rework rates. The design is particularly effective in operations where reliable chip evacuation and edge security are critical to cycle time reduction.

Process security and productivity for series production

Built for stability under medium to robust conditions, this indexable insert supports consistent cycle times and predictable tool life. The combination of coated WMP20S grade and the RM5 breaker contributes to a stable cutting edge that withstands the demands of serial production on rostfreier Stahl. This means fewer unscheduled stoppages, improved surface consistency, and a better yield from each workpiece. For production engineers, the predictability afforded by the insert simplifies process planning and inventory management, as tool change intervals become easier to estimate and integrate into machining schedules.

Recommended applications and material behaviour explained

The insert is optimised for machining rostfreier Stahl (ISO group M), materials that typically show toughness, a tendency to work-harden and to form long, stringy chips. The coated carbide and the dedicated chipbreaker mitigate these tendencies by promoting a stable chip form and reducing the formation of built-up edge. Typical applications include external turning and light profiling in medium to robust cutting conditions where edge durability and chip control are priorities. When selecting cutting parameters, a combination of moderate cutting speeds and appropriate feeds will help exploit the insert’s strengths for long tool life and consistent surface quality.
