DNMG150408-RM5 WMP20S indexable turning insert — Tiger·tec Silver, RM5 chipbreaker (Walter Tools)

The DNMG150408-RM5 WMP20S is a rhombic 55° indexable turning insert designed for reliable machining of stainless steel in medium to tough cutting conditions.

• Tiger·tec Silver coated carbide grade WMP20S
• Optimised for machining stainless steel
• RM5 chipbreaker for stable chip formation
• Negative 0° relief for robust cutting

Maximise productivity with a coating engineered for stainless steel

The Tiger·tec Silver coating and the WMP20S coated carbide grade are tuned for the specific demands of stainless steel: tendency to gall, high heat generation and ductile chips. The combination offers improved wear resistance and thermal stability, which reduces flank wear and extends edge life under continuous loads. For manufacturers this means fewer insert changes and more predictable tool cycles, supporting stable production rates and consistent component quality.

Reliable chip control and form stability for consistent results

The RM5 chipbreaker ensures controlled chip formation and evacuation, lowering the risk of built-up edge and improving surface finish in interrupted or robust cuts. Coupled with the rhombus 55° geometry, the insert provides flexibility across a wide range of turning operations, from light finishing to heavier roughing tasks. The relatively large 0.8 mm corner radius increases edge strength, delivering repeatable performance where tool life and process reliability are priorities.

Robust geometry for demanding turning conditions

With a negative 0° relief and execution code G, the insert is configured for secure cutting where stability is essential. The negative rake characteristic supports higher feed and depth-of-cut combinations while limiting chatter on less rigid setups. This geometry, together with the coated carbide grade, offers a practical balance between cutting force tolerance and surface integrity, making the insert suitable for shops seeking reproducible results on corrosion‑resistant alloys.

Practical benefits for the workshop and process planners

The insert’s form and cutting data are compatible with common toolholders for DNMG-style rhombic inserts, simplifying tool‑set standardisation. The product is suited to serial production and single‑part manufacturing alike: the combination of Tiger·tec Silver and the RM5 chip control reduces unplanned downtime and supports predictable reconditioning intervals. For planners, this translates into easier capacity planning and lower overall machining costs per part.

FAQ

What materials is this insert intended for?
The insert is designed primarily for machining stainless steel; the WMP20S grade and Tiger·tec Silver coating support secure chip formation and improved wear resistance when cutting such alloys.

How does the RM5 chipbreaker affect machining?
The RM5 chipbreaker promotes controlled chip segmentation and evacuation, reducing the likelihood of built‑up edge and improving surface quality in turning operations.

What does the 0.8 mm corner radius mean for performance?
A 0.8 mm corner radius strengthens the cutting edge, improving tool life and robustness in roughing or interrupted cuts while influencing the achievable surface finish.

Is the negative 0° relief suitable for heavier cuts?
Yes; the negative 0° relief increases edge stability and is appropriate for heavier cutting conditions where higher cutting forces occur.

Can the insert be used in common DNMG toolholders?
The rhombic 55° form conforms to standard DNMG interfaces; compatibility with specific holders should be checked against holder specifications and recommended cutting data.
