CNMG120408-MP3 WPP05G turning insert — Tiger·tec Gold, MP3 chipbreaker (Walter Tools)

The CNMG120408-MP3 WPP05G is a rhombic 80° turning insert designed for reliable steel machining in medium to heavy production environments.

• Tiger·tec Gold coating for extended tool life
• MP3 chipbreaker for stable chip control
• Rhombic 80° form for versatile turning
• 0.8 mm corner radius for robust surface finishes

Optimised coating and grade for longer intervals between tool changes

The insert is built on a coated carbide substrate and finished with Tiger·tec Gold, a high-performance coating that improves wear resistance and maintains edge stability under the thermal loads typical of steel turning. The WPP05G grade has been engineered to balance hardness and toughness, which results in reliable performance across a broad range of steel alloys. This combination reduces the frequency of tool changes and contributes to predictable component quality over longer production runs.

Controlled chip formation for safer, more consistent machining

Equipped with the MP3 chipbreaker, the geometry directs chip flow and minimises erratic swarf. The chipformer is calibrated for common steel machining parameters, enabling secure evacuation of chips at both moderate and higher cutting depths. As a result, machine uptime is improved and part rework due to chip interference is reduced, which supports safer workshop conditions and higher first-pass yield.

Geometry that supports versatile set-up and repeatable results

The rhombic 80° plate form and 0° negative clearance provide a robust cutting edge for a variety of turning operations, from roughing to finishing. The 0.8 mm corner radius offers a compromise between strength and surface quality, helping to avoid premature edge chipping while still achieving acceptable finishes on turned parts. The insert’s compact dimensions and standard designation facilitate straightforward toolholder selection and repeatable indexing.

Application range and practical benefits for steel machining

This insert is specified for ISO P materials and is particularly suitable where a combination of productivity and consistent component quality is required. The grade and chipbreaker pairing support efficient swarf control and stable cutting across unalloyed and alloyed steels. For production environments aiming to reduce process variability, the insert contributes to predictable tool life and easier process tuning, while the Walter Tools backing ensures availability and data support for process planning.

FAQ

Which materials are suitable for this insert?
The CNMG120408-MP3 WPP05G turning insert is specified for steel (ISO P) and is optimised for the typical heat and chip formation encountered when machining unalloyed and alloyed steels.

What advantages does the Tiger·tec Gold coating provide?
Tiger·tec Gold on the WPP05G grade increases wear resistance and edge stability, which extends tool life and supports consistent surface quality during longer production runs.

How does the MP3 chipbreaker affect machining performance?
The MP3 chipbreaker is designed to produce short, controllable chips under a range of cutting conditions, improving chip evacuation and reducing the risk of swarf-related interruptions when turning steel.

Why choose a 0.8 mm corner radius?
A 0.8 mm corner radius offers enhanced edge strength for robust cutting while still allowing good surface finish capability, making it a practical choice for mixed roughing and finishing cycles.

How is the insert designated for ordering and identification?
Identification is via the ISO designation CNMG120408-MP3 WPP05G and the SKU CNMG120408-MP3-WPP05G-WALTER, which ensures the correct grade, chipbreaker and form are supplied.
