DNMG150412-MP3 WPP20G turning insert for steel — Walter Tools

The DNMG150412-MP3 WPP20G is a negative-geometry, rhombic 55° turning insert designed for general steel machining with a focus on stable chip control and extended tool life.

• Tiger·tec Gold coating for extended life
• MP3 chipbreaker for controlled chips
• Rhombic 55° geometry for versatile turning
• Corner radius 1.2 mm for robust edge

High productivity through optimised coating and chip control

The combination of the Tiger·tec Gold coating and the MP3 chipbreaker is engineered to increase process stability during steel machining. The coating reduces flank wear and improves heat resistance, which translates into longer tool life and fewer indexings. The chipbreaker promotes short, consistent chips that reduce the risk of entanglement and improve surface finish. These technical choices aim to lower overall machining costs by reducing downtime and conserving machine hours while maintaining throughput.

Geometry that balances versatility and strength

The rhombic 55° shape with a 1.2 mm corner radius and 0° negative rake offers a balance between precision and robustness. The rhombic geometry supports both turning and light profiling, while the larger corner radius enhances edge strength for interrupted cuts or heavier feed rates. The negative rake provides a stronger cutting edge which is advantageous for stable roughing passes. For customers unfamiliar with insert geometry, this means fewer insert changes and a simpler tooling setup for mixed turning tasks.

Suitable for a wide range of steel applications

Specifically designed for the material group P, the insert’s substrate and coating combination is tuned to handle unalloyed and alloyed steel grades commonly encountered in general engineering and production environments. The WPP20G grade is a coated carbide formulation that prioritises wear resistance and a broad workpiece compatibility. For shops seeking a reliable general-purpose solution, this grade minimises the need for multiple specialised inserts and supports consistent part quality across batch runs.

Integration into tooling systems and process planning

The insert follows standard DNMG dimensions and can be used in compatible toolholders for indexable turning inserts. Tooling setup benefits from the insert’s predictable performance: fewer unexpected failures, consistent chip form and stable surface finishes. When planning feeds and depths of cut, consider the insert’s robust edge geometry for moderate to heavy passes and use the MP3 chipbreaker to maintain safe chip evacuation. For detailed cutting parameters, consult tooling charts or Metav Werkzeuge’s application support to align speeds and feeds with machine capabilities.

FAQ

What materials is this insert suitable for?
The DNMG150412-MP3 WPP20G is designed primarily for the P group (steel); the WPP20G grade and Tiger·tec Gold coating optimise wear resistance and chip control in steel machining.

What does the MP3 chipbreaker provide in practice?
The MP3 chipbreaker on this insert produces short, controllable chips and contributes to safer chip evacuation and improved surface finish during standard turning operations.

Is the insert suitable for heavy roughing cuts?
Yes, the combination of a 1.2 mm corner radius and negative 0° rake gives enhanced edge strength that suits heavier feeds and interrupted cuts within the insert’s application range for steel.

Can this insert be used in standard DNMG toolholders?
The DNMG designation indicates compatibility with the corresponding DNMG indexable turning toolholders; ensure the holder accepts the specified insert seat and clamp style.

What advantages does the Tiger·tec Gold series offer?
Tiger·tec Gold provides improved heat resistance and wear performance in coated carbide grades, which helps extend tool life and maintain consistent results over production runs.
