DNMG150608-MU5 WMP20G turning insert — Walter Tools, Tiger·tec Gold, for stainless steel

DNMG150608-MU5 WMP20G is an indexable turning insert designed for stable machining of stainless steel under medium to heavy conditions

• Tiger·tec Gold coating for stainless steel
• MU5 chipbreaker for controlled chips
• Negative 0° rake for robust cutting
• Rhombic 55° shape for versatile turning

Designed for consistent chip control and longer tool life

The DNMG150608-MU5 WMP20G indexable insert combines a coated carbide substrate with the Tiger·tec Gold coating technology to improve edge stability and resistance to wear. The integrated MU5 chipbreaker promotes stable chip formation, reducing the risk of built-up edge on demanding stainless steels. For production environments where repeatability and tool life are decisive, this combination reduces downtime and supports a steady machining cadence while maintaining component quality.

Robust geometry for dependable turning performance

The rhombic 55° form with a corner radius of 0.8 mm and a negative 0° rake provides a geometry that copes well with the toughness and heat generation typical of stainless steels. The negative rake strengthens the cutting edge, which is beneficial for interrupted cuts and heavier feed rates, while the moderate corner radius balances edge strength with surface finish. The coated grade is engineered to maintain a reliable cutting edge under thermal and mechanical stress, delivering predictable performance in series production.

Practical benefits and application guidance

Specifically tailored for machining rostfreier Stahl (stainless steel in ISO group M), the insert supports efficient chip evacuation and consistent surface quality in demanding applications. The MU5 chipbreaker is particularly effective when transitioning from finishing to more robust turning operations, as it helps avoid long, stringy chips that complicate unattended machining. For detailed application parameters or recommendations for specific stainless steel grades, Metav Werkzeuge can provide cutting data and selection advice to match the machining strategy and machine capability.

FAQ

What materials is this insert intended for?
The DNMG150608-MU5 WMP20G insert is optimised for machining stainless steel (ISO group M), providing controlled chips and improved edge life in these materials.

How does the MU5 chipbreaker affect machining?
The MU5 chipbreaker on this Walter Tools insert promotes stable chip formation, which reduces chip entanglement and supports unattended or serial turning operations.

Why choose a negative 0° rake for cutting stainless steel?
A negative 0° rake increases edge robustness and resistance to edge chipping during heavy or interrupted cuts, which is advantageous when machining tougher stainless steels.

Is the Tiger·tec Gold coating suitable for high temperatures?
The Tiger·tec Gold coating enhances wear resistance and thermal stability compared with uncoated grades, helping to maintain cutting edge integrity under the higher heat typical of stainless steel machining.

Can this insert be used for finishing operations?
Yes; with the 0.8 mm corner radius and coated grade, the insert can achieve a balance between surface finish and durability, suitable for light finishing to medium turning tasks.
