CNMG120404-MP3 WPP20G indexable turning insert — Tiger·tec Gold, MP3 chipbreaker for Steel | Walter Tools

The CNMG120404-MP3 WPP20G is a rhombic 80° indexable turning insert engineered for medium to heavy-duty steel machining and designed to deliver stable chip control and long tool life.

• Tiger·tec Gold coating for improved wear resistance
• MP3 chipbreaker optimised for steel turning
• Rhombic 80° form for versatile cutting angles
• 0.4 mm corner radius for consistent edge strength

Increased productivity through optimised coating and grade

The combination of the Tiger·tec Gold coating and the WPP20G grade ensures improved wear resistance and stable cutting behaviour when machining steels. This coating technology reduces flank wear and extends tool life, which translates into fewer tool changes and higher machine uptime. By using an indexable insert with a coating optimised for the heat and chip formation typical of steel turning, process stability is maximised and rework is reduced, supporting predictable production cycles and lower unit costs.

Precise chip control for safer, uninterrupted machining

Built with the MP3 chipbreaker, the insert delivers consistent chip segmentation and evacuation under a wide range of cutting conditions. Reliable chip control minimises chip entanglement and machine downtime, improving operator safety and surface integrity of the workpiece. The chipbreaker geometry is particularly effective in handling the swarf generated from unalloyed and alloyed steels, offering a tangible benefit in automated or batch production where uninterrupted cycles are crucial.

Geometry and edge design that support repeatable results

The rhombic 80° form combined with a 0.4 mm corner radius offers a balance between strength and versatility: the angle provides access to varied turning contours while the rounded corner improves edge robustness against mechanical and thermal shock. Negative 0° clearance geometry contributes to a stable cutting edge in heavy cut scenarios, resulting in fewer vibrations and a more consistent surface finish. These characteristics make the insert suitable for both roughing and mixed finishing tasks in steel applications.

Integration into production and process support

This insert is straightforward to integrate into existing toolholders designed for CNMG‑style indexable plates, enabling quick changeovers and consistent positioning. Using a coated carbide grade tuned for steel machining reduces set‑up experimentation: cutting parameters can be aligned with standard recommendations for coated carbide in steel, simplifying process documentation and operator training.
