• 0° negative rake, 0.8 mm corner radius

Reliable performance where heat and toughness matter

The WSM20S grade within the Tiger·tec Silver family is tailored for materials classified under ISO groups M and S, combining a coated‑carbide microstructure with a surface treatment that improves heat resistance and wear behaviour. This results in stable chip formation and a reduced tendency for built‑up edge when machining workhardening stainless steels and nickel‑based alloys. Engineers looking for predictable tool life will appreciate the controlled flank wear progression provided by the grade, which helps maintain component tolerances and reduces unplanned tool changes.

Geometry engineered for chip control and surface finish

The rhombic 55° geometry paired with a 0.8 mm corner radius balances strength and accessibility, allowing productive finishing and semi‑finishing passes on complex contours. The 0° negative rake (negative freedom angle) increases edge robustness, making the insert suitable for interrupted cuts and heavier depths of cut while still delivering acceptable surface quality. Where a fine surface is required, the combination of corner radius and cutting edge preparation supports consistent results without excessive vibration.

Coating and edge technology for longer intervals between changes

The insert’s Tiger·tec Silver coating provides thermal shielding and improved hardness at elevated temperatures, which is especially beneficial when cutting alloys that generate large amounts of heat at the cutting edge. The NMT chipbreaker geometry is designed to control chip flow and breakage in the specified material groups, lowering the risk of rework or machine downtime. For production environments, this means fewer tool indexings and more parts per tool life, boosting overall process efficiency.

Practical integration and recommended applications

This insert is supplied in the DNMG form factor and fits standard DNMG toolholders; compatibility should be checked against existing clamping systems before use. The grade is recommended for continuous turning and medium‑to‑heavy operations in stainless steel and heat‑resistant alloys; adjustments to feeds and speeds are advised to account for workpiece hardness and part geometry. The tolerance class M indicates consistent dimensional accuracy for reliable seat fit and repeatable performance across indexings.

FAQ

What materials is this insert best suited for?
The DNMG150608-NMT WSM20S insert is engineered for ISO groups M and S, specifically stainless steels and heat‑resistant superalloys where thermal stability and edge strength are critical.

How does the NMT chipbreaker affect machining?
The NMT chipbreaker on the WSM20S grade promotes predictable chip control and compact chip forms in the intended material groups, supporting continuous production and reducing the risk of entanglement.

Is the insert compatible with standard DNMG toolholders?
Yes, the DNMG150608-NMT format is compatible with holders designed for DNMG inserts; however, correct clamping and seat condition should be verified before production use.

What advantages does the Tiger·tec Silver coating provide?
The Tiger·tec Silver coating enhances thermal resistance and wear performance, extending tool life under elevated cutting temperatures typical when machining stainless steels and superalloys.

What cutting-edge conditions are recommended for initial tests?
Start with moderate feeds and conservative cutting speeds for the DNMG150608-NMT WSM20S and adjust based on observed tool wear and surface finish to find the optimal balance between productivity and tool life.
