DNMG110404-FM5 WMP20S turning indexable insert — Tiger·tec Silver for stainless steel | Walter Tools

DNMG110404-FM5 WMP20S is a rhombic-turning insert designed for medium to robust machining of stainless steel, offering a secure chipflow and consistent edge stability

• Tiger·tec Silver coating for high process security
• WMP20S grade optimised for stainless steel
• Negative rake 0° for robust cutting forces
• 0.4 mm corner radius for versatile finishing

Maximised process reliability when turning stainless steel

The combination of the WMP20S carbide grade and the Tiger·tec Silver surface technology supports stable chip formation when machining austenitic and other stainless steels. The metallurgical design reduces the tendency for built-up edge and thermal softening, which in turn maintains cutting-edge integrity over longer tool life. For production environments where consistent cycle times matter, this insert improves process predictability and contributes to fewer unplanned tool changes.

Consistent surface quality and predictable tool life

With a FM5 chipbreaker and a 0.4 mm corner radius, the insert balances chip control with surface finish, enabling reliable results in both semi-finishing and finishing passes. The negative rake 0° geometry increases edge strength under heavy cuts, reducing the risk of chipping on interrupted cuts. These characteristics translate into improved component quality and lower rework rates, supporting more efficient downstream operations.

Easy integration and practical handling in turning operations

The rhombic 55° form and standard DNMG designation allow straightforward integration into common toolholders and turning systems. The insert thickness and seat dimensions conform to industry standards, simplifying tool inventory and changeover. Operators will benefit from a familiar mounting routine while process engineers gain a tool that performs under varying cutting parameters, enabling faster setup and reduced machine downtime.
