DNMG110412-RM5 WSM20S — Indexable turning insert, Tiger·tec Silver (Walter Tools)

The DNMG110412-RM5 WSM20S is an indexable turning insert designed for heavy-duty machining of stainless steels and heat‑resistant alloys, offering a rhombic 55° geometry for versatile cutting applications.

• Tiger·tec Silver coating for heavy-duty turning
• RM5 chipbreaker for reliable chip control
• Rhombic 55° geometry, 1.2 mm corner radius
• Negative 0° rake for stable cutting edge

High‑temperature coating for tough materials and longer tool life

The combination of the Tiger·tec Silver coating and the WSM20S grade is engineered for machining difficult‑to‑cut materials. Coating technology improves wear resistance and reduces adhesion when working with stainless steels and superalloys, which tend to generate heat and cause built‑up edge. This results in more predictable tool life and fewer unscheduled tool changes, supporting continuous production and higher overall productivity. The enhanced substrate and coating pairing is a practical choice where process stability is a priority.

Geometry that secures edge strength and surface quality

The rhombic 55° form with a corner radius 1.2 mm and negative 0° rake provides a robust cutting edge that resists chipping under intermittent engagement and heavy feeds. A larger corner radius distributes cutting forces over a broader area, improving surface finish on turned components while reducing the risk of premature edge breakdown. The negative rake angle contributes to mechanical strength at the cutting edge, making this insert suitable for interrupted cuts and demanding turning operations.

Controlled chip formation for efficient machining

The RM5 chipbreaker is tailored to produce short, manageable chips when turning materials that otherwise form long, springy swarf. Improved chip control reduces cycle interruptions and minimises the need for additional chip handling measures at the machine, contributing to safer, more efficient shopfloor operation. With consistent chip shape and evacuation, coolant and feed strategies can be optimised to maintain dimensional stability and part quality.

Application guidance and process benefits

This grade is specified for M and S groups according to ISO 513, covering stainless steels and heat‑resistant alloys including titanium families. When paired with appropriate cutting parameters and toolholder rigidity, the insert supports reproducible results and extended operational sequences. Using the DNMG geometry in suitable holders allows straightforward index changes and rapid re‑engagement in production, reducing setup time and improving overall throughput.

FAQ

What materials is this insert designed to machine?
The DNMG110412-RM5 WSM20S from Walter Tools is specified for ISO groups M and S, making it suitable for stainless steels and heat‑resistant superalloys.

How does the RM5 chipbreaker influence machining?
The RM5 chipbreaker on the WSM20S grade produces compact chips and improves evacuation, which reduces interruptions and supports smoother turning cycles with the Walter Tools insert.

Is the negative 0° rake suitable for interrupted cuts?
Yes, the negative 0° rake and the rhombic geometry increase edge strength and resilience, so the insert handles interrupted cuts and heavy engagement more reliably.

What benefits does the Tiger·tec Silver coating provide?
The Tiger·tec Silver coating enhances wear resistance and reduces adhesion tendency on difficult materials, extending tool life and maintaining surface quality during extended runs.
