WNMG060408-RM5 WSM20S trigon turning insert by Walter Tools — Tiger‑tec Silver coated, RM5 chipbreaker

WNMG060408-RM5 WSM20S is a trigon 80° turning insert designed for heavy‑duty machining of rostfreier Stahl and heat‑resistant alloys, delivering secure chip formation and extended edge life.

• Tiger‑tec Silver grade WSM20S
• Trigon 80° insert geometry
• Corner radius 0.8 mm
• RM5 chipbreaker for secure chip control

Increased uptime through a heat‑resistant grade

The WSM20S grade, part of the Tiger‑tec Silver family, is a coated carbide developed for high temperatures and adhesive wear typical of rostfreie Stähle and nickel‑based superalloys. Its multilayer coating improves thermal resistance and reduces chemical affinity at the cutting edge, which means fewer built‑up edge occurrences and longer periods between index changes. For production environments where edge stability reduces rework and unscheduled stoppages, this insert supports a more predictable machining cycle and lower overall unit cost per part.

Stable geometry for consistent surface quality

A Trigon 80° shape combined with a negative rake 0° geometry gives the insert superior edge robustness under interrupted cuts and shoulder work. The corner radius 0.8 mm balances strength and finish, offering improved resistance to chipping while maintaining acceptable surface integrity. The built‑in RM5 chipbreaker is optimised for secure chip formation with medium to heavy depth of cut ranges, reducing the risk of long, stringy chips that impair operator safety and machine uptime. Together, these features support repeatable part quality and reduced scrap rates.

Application focus and economic benefits

This insert is suitable for rostfreier Stahl as well as demanding alloys such as superalloys and titanium, where heat generation and poor thermal conductivity stress the cutting edge. In practical terms, the grade and geometry combination reduces the frequency of index changes and toolholder adjustments, enabling higher effective machine utilisation. For job shops and production lines machining difficult materials, the result is improved first‑pass yield and a measurable contribution to throughput. The WNMG060408-RM5 WSM20S insert integrates with standard WNMG toolholders and can be specified where process reliability and edge life are priorities.

FAQ

What materials is this insert best suited for?
The WNMG060408-RM5 WSM20S insert is optimised for rostfreier Stahl and heat‑resistant alloys such as nickel‑base superalloys and titanium, where its Tiger‑tec Silver coating and grade stability reduce built‑up edge and thermal wear.

How does the RM5 chipbreaker affect machining performance?
The RM5 chipbreaker promotes secure, controlled chips under medium to heavy cuts, which improves process safety and reduces interruptions caused by tangled chips when using the WNMG060408-RM5 WSM20S insert.

Can the insert handle interrupted cuts and shoulder machining?
Yes — the Trigon 80° form combined with a negative rake and a 0.8 mm corner radius provides increased edge robustness for interrupted cuts and shoulder work, helping to maintain chip control and part quality.

Is this insert compatible with standard WNMG toolholders?
The geometry and ISO designation correspond to standard WNMG toolholder interfaces, allowing straightforward replacement and integration into existing tool setups when selecting the WNMG060408-RM5 WSM20S insert.

Which coating advantages does Tiger‑tec Silver provide?
The Tiger‑tec Silver coating increases thermal stability and reduces chemical adhesion at the cutting edge, which helps extend edge life and supports machining of materials that tend to generate high temperatures and built‑up edge.
