SNMM120412-HU5 WSM30S indexable turning insert (square 90°, Tiger‑tec Silver) — Walter Tools

SNMM120412-HU5 WSM30S is a square 90° indexable turning insert designed for demanding machining of stainless steels and heat‑resistant superalloys; optimised for stability under thermal and mechanical load

• Tiger‑tec Silver coated carbide grade WSM30S
• Designed for stainless steel and superalloys
• Square 90° form with 1.2 mm corner radius
• Negative rake 0°; HU5 chipbreaker geometry

Proven grade for tough-to-machine materials

The WSM30S grade in the Tiger‑tec Silver series combines a coated cemented carbide substrate with surface engineering that enhances heat resistance and wear protection. This configuration promotes stable chip formation when cutting stainless steels and nickel‑based alloys, which tend to work‑harden and generate heat. The result is more consistent tool life and fewer interruptions in production, supporting predictable cycle times and reduced regrinding frequency for the toolroom.

Geometry tailored to strength and surface quality

The insert’s square 90° form and 1.2 mm corner radius provide a robust cutting edge suited to medium‑duty roughing and finishing operations. A 0° (negative) relief angle increases edge stability under radial load, while the HU5 chipbreaker is shaped to control chip flow for long, stringy material behaviour typical of stainless and high‑temperature alloys. Together these features help maintain a consistent surface finish without sacrificing edge security during interrupted cuts.

Process reliability and economical machining

By pairing a resilient geometry with the Tiger‑tec Silver surface, the insert supports higher process stability and extended tool life, which lowers the frequency of insert changes and machine downtime. The combination of grade and chipbreaker allows for balanced cutting parameters that favour both metal removal rate and component quality.

FAQ

What materials is this insert suitable for?
The SNMM120412-HU5 WSM30S insert by Walter Tools is specified for stainless steels (ISO group M) and for heat‑resistant superalloys and titanium (ISO group S), reflecting the grade’s focus on heat resistance and edge stability.

How does the HU5 chipbreaker affect machining?
The HU5 chipbreaker is engineered to control chip formation in materials that tend to produce long, stringy chips; when combined with the Tiger‑tec Silver surface, it improves chip evacuation and reduces the risk of built‑up edge.

When is the 1.2 mm corner radius recommended?
A 1.2 mm corner radius increases edge strength and is beneficial for higher depth cuts and semi‑roughing where robustness is required; it also influences the achievable surface finish and should be chosen according to the part tolerance.

Does the Tiger‑tec Silver coating improve tool life?
Yes, the Tiger‑tec Silver coating on the SNMM120412-HU5 WSM30S insert enhances thermal stability and wear resistance, contributing to longer tool life and more consistent performance in demanding materials.

What is the geometry and how does it impact setup?
The square 90° insert with a 0° negative relief angle provides a strong cutting edge for axial and radial loads; toolholder selection must accommodate the insert form and negative rake to ensure correct seating and cutting clearance.
