SNMG120412-MM5 WSM20S — Turning indexable insert, Tiger·tec Silver coating, 1.2 mm corner radius — Walter Tools

The SNMG120412-MM5 WSM20S is a square turning insert engineered for heavy-duty turning of rostfreier Stahl and heat-resistant superalloys, offering a stable cutting edge and secure chip formation in demanding environments.

• Tiger·tec Silver coating for high process security
• WSM20S grade for rostfreie Stähle and superalloys
• Square 90° form with 1.2 mm corner radius
• Negative 0° rake for robust engagement

Improved process reliability for difficult-to-cut alloys

The coated carbide grade WSM20S delivers stable performance when machining rostfreier Stahl and temperature-resistant alloys. Thanks to the Tiger·tec Silver technology, the insert resists thermal softening and maintains edge stability under elevated cutting temperatures. This results in fewer unexpected tool changes and more predictable cycle times, which supports higher machine utilisation and reduced production interruptions.

Precision chip control and surface quality

Equipped with the MM5 chipbreaker and a square 90° geometry, the insert promotes secure chip formation and controlled evacuation, reducing the risk of built-up edge and preventing workpiece damage. The 1.2 mm corner radius helps achieve consistent surface finish while providing the mechanical strength needed for interrupted cuts. These features together enable both improved part quality and a reduction in rework for time-critical jobs.

Robust geometry for heavy engagement and repeatability

The negative 0° rake and proven substrate design give the insert a high resistance to flank and crater wear during sustained heavy cutting. The combination of coated hardmetal and a stable cutting edge is ideal for operations where repeatable results and long insert life are required. Specified tolerance class M ensures consistent interchangeability and process reproducibility across toolholders and batches.

Application guidance and practical benefits

This insert is suited for turning applications involving rostfreier Stahl as well as selected superalloys and titanium depending on component geometry. The SNMG120412-MM5 format fits common ISO toolholders for versatile setup options. When paired with correct cutting parameters and appropriate coolant strategy, the result is efficient metal removal, improved tool life and a measurable reduction in unplanned downtime.
