DNMG110408-RM5 WMP20G – Indexable turning insert, coated carbide for stainless steel (Walter Tools)

The DNMG110408-RM5 WMP20G is an indexable turning insert engineered for reliable finishing and semi‑roughing of stainless steel under moderate to robust conditions.

• Tiger·tec Gold coated for long life
• Suitable for stainless steel machining
• Rhombic 55° shape, 0.8 mm corner radius
• Chipbreaker RM5 for stable chip control

Maximise productivity with advanced coating technology

The Tiger·tec Gold coating combined with the WMP20G grade provides a balance of wear resistance and edge strength that translates directly into longer tool life and fewer tool changes. Coated carbide means a wear‑resistant layer on a cemented carbide substrate; this reduces flank wear and helps maintain cutting geometry over longer runs, increasing uptime and lowering per‑part tooling costs. For operations where cycle time and repeatability matter, this combination supports consistent performance across batches.

Reliable chip control for challenging stainless steel

Inserts for stainless steel must handle material toughness and a tendency to form built‑up edge. The RM5 chipbreaker is designed to produce short, controllable chips and to avoid stringing that can damage the workpiece or tool. Stable chip formation reduces the risk of surface defects and chucking issues, improving process stability. For shops moving between roughing and finishing, a predictable chip flow reduces cycle interruptions and eases chip evacuation from narrow bores and tight fixtures.

Robust geometry that protects the cutting edge

The rhombic 55° insert geometry, combined with a 0.8 mm corner radius and a negative rake of 0°, enhances edge strength for interrupted cuts and higher radial engagement. A larger corner radius distributes cutting forces over a greater area, improving resistance to edge chipping and enhancing surface finish when used at appropriate feeds. Negative rake geometry increases mechanical robustness, making the insert suitable where rigidity is limited or where light interrupted cutting occurs.

Practical application and economic benefits on the shop floor

This insert fits standard holders for DNMG‑style tools, enabling straightforward integration without special tooling. Selection of the WMP20G grade for stainless steel supports a broad range of stainless alloys, offering a practical compromise between durability and versatility. Reduced frequency of indexings and longer periods between replacements mean lower disposal and handling effort, contributing to total cost of ownership savings while maintaining quality and process reliability.

FAQ

What material group is this insert best suited for?
The DNMG110408-RM5 WMP20G insert from Walter Tools is optimised for stainless steel (material group M) and supports stable chip formation in such alloys.

How does the Tiger·tec Gold coating benefit production?
The Tiger·tec Gold coating on the WMP20G grade increases wear resistance and edge stability, which extends tool life and helps maintain consistent surface quality during longer production runs.

Can this insert handle interrupted cuts?
Yes; the rhombic 55° geometry with a 0.8 mm corner radius and negative rake improves edge strength, making the insert suitable for light to moderate interrupted cuts.

Is the RM5 chipbreaker suitable for finishing operations?
The RM5 chipbreaker is designed for controlled chip formation and can be used effectively in finishing when combined with appropriate feeds and speeds for stainless steel.

Which holders are compatible with this insert form?
The DNMG form is a standard indexable turning shape; the DNMG110408-RM5 WMP20G fits holders designed for DNMG inserts, enabling easy replacement in common turning tool systems.
