DCMT150408 WSM20S — Turning indexable insert DCMT150408 WSM20S (Tiger·tec Silver) by Walter Tools, 7° clearance, 0.8 mm nose radius

DCMT150408 WSM20S is an indexable turning insert designed for machining demanding materials such as rostfreier Stahl and heat-resistant superalloys, providing a balance of edge stability and wear resistance

• Tiger·tec Silver coating for heat resistance
• Optimised for rostfreier Stahl and superalloys
• Rhombic 55° form, 7° clearance
• 0.8 mm nose radius for reliable surface finish

High-performance coating and grade for continuous productivity

The combination of the Tiger·tec Silver coating and the WSM20S grade delivers improved thermal stability and reliable edge integrity when machining stainless and high-temperature alloys. The coated cemented carbide substrate provides a protective layer that reduces adhesive wear and supports stable chip formation under elevated cutting temperatures. This translates into longer tool life and fewer insert changes, which directly improves machine uptime and lowers process costs. For operations facing built-up edge or rapid flank wear on rostfreier Stahl, the coated grade is a pragmatic choice that helps maintain consistent component geometry.

Geometry tuned for surface quality and process security

The rhombic 55° insert profile and the 7° clearance angle reduce cutting forces in many turning applications, while the 0.8 mm corner radius provides a compromise between strength and surface finish. The DCMT form is suitable for both medium-duty roughing and finishing passes when paired with the right cutting data. A stable cutting edge and the insert’s geometry enhance vibration resistance and contribute to an even surface texture on the workpiece. Selecting the correct feed and depth of cut in line with the insert’s geometry supports predictable results and reduces scrap rates.

Practical application guidance for demanding alloys

This insert is particularly recommended for components made from rostfreier Stahl and materials classified in group S (superalloys and titanium) according to ISO recommendations. The WSM20S grade is engineered for high-temperature performance and is well suited to applications where heat conduction away from the cutting edge is limited. Use coolant strategies and cutting parameters that balance tool life and productivity; modest increases in cutting speed are often possible thanks to the coating’s thermal tolerance, unlocking faster cycle times without compromising edge stability. The robust design of the insert supports repeatable results in series production and helps to secure process reliability across similar batches.

FAQ

What materials is the DCMT150408 WSM20S insert suited for?
The DCMT150408 WSM20S insert by Walter Tools is optimised for rostfreier Stahl and materials in the S group (heat-resistant superalloys and titanium), providing enhanced thermal resistance and stable chip formation.

Can the insert be used for finishing as well as roughing?
Yes, with the 0.8 mm nose radius and the rhombic 55° geometry the insert supports both medium finishing and productive roughing passes when paired with appropriate feeds and speeds.

What advantage does the Tiger·tec Silver coating give?
The Tiger·tec Silver coating increases thermal stability and wear resistance, helping to reduce built-up edge and prolong insert life during machining of high-temperature alloys and rostfreier Stahl.

How does the WSM20S grade differ from uncoated grades?
WSM20S is a coated cemented carbide grade designed for improved edge stability and longer life under heat load, offering more consistent performance than many uncoated alternatives when machining difficult-to-cut materials.

Which insert holders are compatible with DCMT150408?
DCMT150408 is a standard DCMT-form indexable insert (rhombic 55°) and fits holders designed for DCMT15 inserts; verify seat and clamping specifications with the chosen toolholder manufacturer.
