TNMG160412-MM5 WMP20S triangular turning insert, Walter Tools — Tiger·tec Silver for stainless steel

The TNMG160412-MM5 WMP20S is a triangular 60° indexable turning insert designed for productive machining of stainless steel under medium to robust cutting conditions.

• Tiger·tec Silver coating for wear resistance
• WMP20S grade optimised for stainless steel
• Triangular 60° form with 1.2 mm corner radius
• Negative 0° rake for stable cutting

High wear resistance for reliable stainless-steel turning

The coated-carbide composition from the Tiger·tec Silver series is engineered for reliable performance when machining stainless steel. The WMP20S grade is a coated carbide variant that supports secure chip formation and a stable cutting edge under the high temperatures and adhesive tendencies typical of this material group. This results in longer cutting intervals and fewer unplanned tool changes, contributing to improved process efficiency and predictable cycle times.

Geometry and chip control that improve surface quality

The triangular 60° plate form combined with the MM5 chipbreaker and a 1.2 mm corner radius is designed to balance strength and finish. The negative 0° rake increases edge robustness and reduces the risk of chipping on interrupted cuts or heavy engagement, while the chipbreaker directs swarf away from the workpiece to reduce recutting. Together, these features support consistent dimensional accuracy and an improved surface finish on turned components.

Suited for medium to robust machining — stable productivity

Selected for ISO group M materials, the insert is intended where moderate to robust cutting parameters are required. The chosen grade and coating provide good resistance to adhesive wear and thermal load, which helps to maintain cutting-edge integrity over repeated cycles. The result is enhanced process security and predictable tool life, which can lower overall machining costs through reduced downtime and fewer insert changes.

Practical fitment and identification for workshop planning

This item is offered in the common TNMG format and is identified by the code TNMG160412-MM5 WMP20S (Walter Tools).
