DNMG150412-MP3 WPP30G turning insert – Tiger·tec Gold for steel | Walter Tools

The DNMG150412-MP3 WPP30G is a single‑sided indexable turning insert engineered for productive steel machining in ISO P applications.

• Tiger·tec Gold coating for high wear resistance
• Grade WPP30G optimised for steel machining
• Rhombic 55° shape with 1.2 mm corner radius
• Negative 0° rake with MP3 chipbreaker for stable chips

Increase machining uptime with a wear‑resistant grade

The combination of the Tiger·tec Gold coating and the WPP30G grade delivers measurable improvements in wear resistance and tool life. Designed for the thermal and mechanical demands of steel cutting, the coated hardmetals reduce flank and crater wear, so machining cycles remain productive for longer. The result is fewer insert changes and higher overall throughput, which supports an efficient production schedule and consistent component quality.

Geometry that guarantees process stability under load

The rhombic 55° geometry and the 1.2 mm corner radius provide a robust cutting edge suited to a variety of turning operations. The 0° negative rake increases edge strength and allows the insert to withstand heavier depths of cut without chipping, making it suitable for semi‑roughing and finishing passes where stability is crucial. These geometric choices contribute directly to predictable tool behaviour and reduced scrap rates in demanding shop environments.

Controlled chips and improved surface quality for steel

The integrated MP3 chipbreaker is tuned for ISO P (steel) applications and promotes short, controllable chip formation even at variable cutting parameters. That control helps maintain a consistent contact zone and improves surface finish on workpieces, while reducing the risk of chip entanglement in automated setups. Using an insert designed for the material group ensures that cycle times and costs per component remain competitive.

Seamless integration into productive tool systems

Marked with the ISO designation and produced to tolerance class M, this indexable insert fits standard DNMG toolholders and is compatible with established tool‑holder programs. The combination of a reproducible coated grade and a well‑defined chipbreaker simplifies grade selection and process documentation in series production. For workshops aiming at process reliability, the insert offers a balance of productivity and repeatable accuracy, backed by Walter Tools' manufacturing standards.

FAQ

Which materials is this insert designed for?
This insert is optimised for steel (ISO group P); the WPP30G grade and Tiger·tec Gold coating suit unalloyed and alloyed steels in turning operations.

What benefits does the Tiger·tec Gold coating provide?
Tiger·tec Gold increases wear resistance and thermal stability, extending service life and supporting consistent machining performance with the DNMG150412‑MP3 WPP30G.

How does the MP3 chipbreaker affect machining?
The MP3 chipbreaker produces short, controllable chips in steel turning, improving surface finish and reducing chip management issues in automated or manual turning processes.

What does a 0° negative rake mean for cutting conditions?
A 0° negative rake enhances edge strength and allows for more robust cutting conditions, enabling heavier cuts and improved reliability when machining tougher sections of steel.

Is this insert compatible with standard toolholders?
Yes, the insert follows DNMG geometry and tolerance class M, making it compatible with conventional DNMG toolholder systems for turning.
