DNMG110408-RM5 WMP20S turning insert — Tiger·tec Silver grade for stainless steel (Walter Tools)

The DNMG110408-RM5 WMP20S is a rhombic 55° indexable turning insert optimised for machining stainless steel under medium to robust cutting conditions.

• Tiger·tec Silver coating
• For stainless steel (ISO M)
• Rhombic 55° geometry
• 0° negative rake angle

Process stability and longer service life through Tiger·tec Silver

The Tiger·tec Silver technology combines a coated carbide substrate with a tailor-made surface finish to reduce flank wear and delay edge breakdown. This results in a more predictable tool life when machining demanding alloys such as stainless steel, which are prone to work-hardening and built-up edge. Reduced wear translates directly into fewer tool changes and less unscheduled downtime, supporting stable series production and improved cost-efficiency per component.

Controlled chip formation and surface quality with RM5 chipbreaker

The RM5 chipbreaker is designed to support secure chip control when cutting tough materials. Combined with the 0° negative rake, the geometry promotes a robust cutting edge that tolerates interrupted cuts and variable material batches. The moderate 0.8 mm corner radius improves surface finish while maintaining edge strength, giving a balance between component quality and resistance to mechanical or thermal edge damage.

Reliable performance in stainless steel applications

Stainless steels require tooling that prevents excessive heat build-up and avoids adhesion on the cutting edge. The WMP20S grade is specified for ISO M workpieces and is tuned to deliver stable chip formation and consistent cutting behaviour under the elevated temperatures associated with these alloys. This focused application profile reduces the need for constant parameter adjustments and aids reproducible machining results across shifts.

Compatibility and economical use in common turning systems

The DNMG format ensures compatibility with standard rhombic toolholders used in production turning and finishing. As an indexable insert, it allows fast reorientation of the cutting edge to restore performance without full regrinding. The combination of an established insert geometry, a dedicated coated carbide grade and a proven chipformer supports both roughing and semi-finishing steps, offering a practical route to reduce tooling costs while maintaining process reliability.

FAQ

What materials is this insert intended for?
The DNMG110408-RM5 WMP20S insert from Walter Tools is specified for stainless steel (ISO M), offering secure chip formation and reliable edge performance in these alloys.

How does Tiger·tec Silver benefit machining?
Tiger·tec Silver on the WMP20S grade provides enhanced wear resistance and thermal stability, which helps maintain cutting-edge integrity and extend usable tool life in demanding stainless-steel operations.

Which chip control can be expected from the RM5 chipbreaker?
The RM5 chipbreaker delivers consistent chip formation for ISO M applications, supporting safer chip evacuation and reducing the risk of edge build-up that can affect surface finish.

Is the rhombic 55° geometry suitable for finishing?
Yes, the rhombic 55° geometry combined with a 0.8 mm corner radius balances strength and finish capability, making it appropriate for both semi-finishing and finishing passes where stability is required.

Will this insert fit standard toolholders?
The DNMG designation aligns with common rhombic insert toolholders, so the DNMG110408-RM5 WMP20S is compatible with widely used turning tool systems without the need for special adapters.
