SNMM190616-HU5 WSM30S indexable turning insert — for stainless steels and superalloys (Walter Tools)

The SNMM190616-HU5 WSM30S is a square indexable turning insert engineered for heavy-duty machining of stainless steels and heat-resistant superalloys, offering high edge stability and controlled chip formation.

• Tiger·tec Silver coated carbide for heat resistance
• Optimised HU5 chipbreaker for controlled chip flow
• Square 90° form with 1.6 mm corner radius
• Negative 0° geometry for secure edge strength

Longer tool life through a heat-resistant coating

The coated carbide specification WSM30S, part of the Tiger·tec Silver family, is designed to resist thermal and mechanical wear when machining stainless steels and nickel-based alloys. The coating increases surface hardness at elevated temperatures and reduces flank wear, which extends effective tool life and lowers downtime for tool changes. For production environments where repeatability and consistent productivity matter, this grade offers a dependable combination of durability and cutting performance that supports extended machining cycles and dependable cycle times.

Predictable chip control and process stability

The HU5 chipbreaker geometry is optimised to produce short, controllable chips under the high heat and built-up-edge tendencies of tough alloys. This results in improved swarf management, reduced risk of re-cutting chips and fewer interruptions at the machine. Process stability is enhanced by the insert’s geometry and the negative 0° cutting angle, which together provide a robust cutting edge especially suited to heavier cuts and interrupted machining. The outcome is less vibration, fewer edge failures and consistent surface quality.

Strong form for secure cutting and good surface finish

The square 90° insert form offers four usable cutting corners and a rigid contact geometry that supports heavy radial forces. Combined with a 1.6 mm corner radius, the insert balances edge strength with the potential for improved workpiece finish, making it suitable for operations where both robustness and acceptable surface integrity are required. The design is particularly effective when machining components that demand repeatable dimensional accuracy and reliable edge behaviour.

Versatile application support for demanding materials

Rated for ISO groups M and S, this insert accommodates stainless steels and heat-resistant superalloys or titanium alloys, addressing materials that typically generate high temperatures and sticky chips. The coated carbide substrate and the insert’s mechanical geometry help prevent rapid tool wear and support secure chip evacuation, which is essential in high-value component production. When process engineers require stable tool performance across varying batch sizes and alloy grades, this insert provides a straightforward, application-oriented solution.

FAQ

What materials is this insert optimised for?
The SNMM190616-HU5 WSM30S insert is optimised for stainless steels (ISO M) and heat-resistant superalloys or titanium (ISO S), offering improved thermal resistance and edge stability for such materials.

How does the HU5 chipbreaker affect machining?
The HU5 chipbreaker on the WSM30S grade promotes short, controlled chips and reliable swarf evacuation, enhancing process stability when machining sticky or heat-generating alloys.

What advantages does the square 90° form provide?
The square 90° form provides multiple usable cutting edges and a rigid geometry that supports higher radial loads and consistent dimensional results during robust turning operations.

Is the insert suitable for interrupted cuts?
Yes; the negative 0° geometry and the 1.6 mm corner radius give the insert a secure cutting edge that tolerates interrupted cuts and reduces the risk of edge chipping.

How does the Tiger·tec Silver coating improve performance?
The Tiger·tec Silver coating increases resistance to thermal and abrasive wear, which prolongs tool life and helps maintain a stable cutting edge in demanding production scenarios.
