CNMG090304-MP3 WPP20G — Turning indexable insert for Stahl by Walter Tools

The CNMG090304-MP3 WPP20G is a rhombic 80° turning insert designed for reliable finishing and medium-duty roughing of Stahl, combining a Tiger·tec Gold coating with an MP3 chipbreaker for consistent chip formation.

• Tiger·tec Gold coated carbide for long life
• Optimised MP3 chipbreaker for controlled chips
• Rhombic 80° form with 0.4 mm corner radius

Consistent chip control for steady production

The insert’s MP3 chipbreaker is engineered for predictable chip segmentation, reducing the risk of built-up edge and machine downtime. In practice, this means smoother evacuation of swarf and fewer interruptions during longer runs. The combination of chip geometry and a negative 0° rake promotes a stable cutting force, which helps maintain dimensional consistency on turned components made of Stahl. Such stability supports improved process reliability and can contribute to higher overall machining throughput.

Coating and grade that extend tool life

The WPP20G grade, part of the Tiger·tec Gold family, is a coated carbide designed for balanced wear resistance and toughness when machining Stahl. The coating improves thermal and abrasive resistance, while the substrate preserves edge integrity under varying cutting conditions. For manufacturers seeking lower tooling costs per component, this balance offers a clear economic advantage through longer indexable insert life and fewer tool changes, leading to greater uptime on production lathes.

Geometry tailored for precision turning

The rhombic 80° form and 0.4 mm corner radius provide a compromise between edge strength and fine surface finish. This geometry supports reliable corner engagement and repeatable profile work, especially when close tolerances are required. The insert’s profile is suitable for a range of applications from light finishing to medium turning, where surface quality and tool stability matter. Its form factor also facilitates secure clamping in common CNMG toolholders, enabling accurate, vibration-resistant machining.

Application scope and handling advice

Designed principally for Stahl according to ISO P classifications, the grade is versatile across unalloyed and alloyed steels with typical heat generation and chip behaviour for this material group. The insert’s coated carbide construction and MP3 chip control make it a good choice for both serial production and small-batch work where consistent results are important. For best results, pair the insert with appropriate cutting parameters and coolant strategies suitable for the workpiece grade; modest depths of cut and optimised feed rates preserve the effective life of the cutting edge.

FAQ

What machining tasks is this insert best suited for?
The CNMG090304-MP3 WPP20G by Walter Tools is aimed at finishing and medium-duty turning of components in Stahl, offering good surface quality and reliable tool life.

How does the MP3 chipbreaker affect performance?
The MP3 chipbreaker on the CNMG090304-MP3 promotes consistent chip segmentation and evacuation, which reduces interruptions and supports continuous production on turning machines.

Is the WPP20G grade suitable for interrupted cuts?
WPP20G combines toughness and wear resistance; it is capable of handling moderate interruptions in cutting when appropriate parameters are applied, as befits many Stahl applications.

Can this insert be used in standard CNMG clamping systems?
Yes, the rhombic 80° form and CNMG designation make the insert compatible with common CNMG toolholders, enabling secure clamping and stable performance.

What corner radius should be used for precision finishing?
The built-in 0.4 mm corner radius provides a balance between edge strength and finish; reducing feed and depth of cut while using this radius aids in achieving finer surface quality with the same insert.
