CNMG120404‑MP3 WPP30G — Turning insert, Tiger‑tec Gold coating, for steel (P) | Walter Tools

The CNMG120404‑MP3 WPP30G is a rhombic 80° turning insert designed for productive steel machining, offering a robust coated carbide grade for demanding shopfloor applications

• Tiger‑tec Gold coating for high durability
• Rhombic 80° shape for versatile turning
• 0.4 mm corner radius for reliable edge strength
• MP3 chipbreaker optimised for steel

High productivity through a specialised coating and grade

The combination of Tiger‑tec Gold technology and the WPP30G grade provides a balance of wear resistance and toughness that is beneficial for continuous turning operations on steel. The coated carbide substrate reduces flank wear at elevated cutting speeds, which extends tool life and lowers the frequency of insert changes. This results in improved process stability and a favourable cost‑per‑component metric for batch and serial production.

Geometry that supports secure machining and consistent accuracy

A rhombic 80° geometry paired with a 0.4 mm corner radius delivers a compromise between edge strength and the ability to achieve close tolerances. The negative 0° clearance helps to maintain a stable cutting edge under interrupted cuts and higher feed rates, reducing the risk of edge chipping. These design choices support repeatable dimensional accuracy and a steady surface quality when tackling a range of turning tasks.

Controlled chip formation for better surface finish and safety

The MP3 chipbreaker is optimised for steel and promotes predictable chip segmentation and evacuation. Controlled chip form reduces the likelihood of long, entangling swarf and contributes to a cleaner working environment and safer tool handling. Improved chip control also aids in achieving a finer surface finish, which can reduce downstream finishing effort and improve overall part quality.

Suitable applications and practical recommendations

This insert is intended for general steel turning under medium to heavy cutting conditions, where a balance of wear resistance and toughness is required. The combination of WPP30G grade and the MP3 breaker is particularly effective for unalloyed and alloyed steels that exhibit typical heat generation and chip behaviour during machining. For optimal results with specific machine setups and workpiece materials, refer to the toolholder compatibility and cutting data provided by Metav Werkzeuge.

FAQ

Which materials is this insert designed for?
The CNMG120404‑MP3 WPP30G insert is optimised for machining steel (ISO group P), with the grade engineered to handle the heat and chip formation typical of unalloyed and alloyed steels.

What does the MP3 chipbreaker provide in practice?
The MP3 breaker on this indexable insert promotes controlled chip segmentation and safe chip evacuation, which improves surface finish and reduces downtime for swarf management when turning steel.

How does the 0.4 mm corner radius affect machining performance?
A 0.4 mm corner radius increases edge strength and resistance to chipping during heavier cuts, contributing to steadier tolerances and longer effective tool life for this Walter Tools turning insert.

Is the Tiger‑tec Gold coating suitable for higher cutting speeds?
Yes, the Tiger‑tec Gold coating on the WPP30G grade enhances wear resistance, allowing for elevated cutting speeds while maintaining stable flank wear behaviour and consistent component quality.

Can this insert be used for finishing operations?
The design and grade of the CNMG120404‑MP3 WPP30G are primarily targeted at medium to heavy turning; finishing is possible with appropriate feeds and speeds, but fine‑finish specific grades may offer superior surface results for dedicated finishing passes.
