CNMG120408-MP3 WPP30G Turning Indexable Insert — Tiger‑tec Gold for steel (Rhombic 80°, 0.8 mm) by Walter Tools

The CNMG120408-MP3 WPP30G is a rhombic 80° turning indexable insert with Tiger‑tec Gold coating, optimised for steel machining and designed for dependable chip control in medium to heavy turning operations

• Tiger‑tec Gold coated carbide WPP30G
• MP3 chipbreaker for consistent chips
• Rhombic 80° geometry, 0.8 mm corner radius
• Optimised for steel machining (ISO P)

Durable cutting performance through Tiger‑tec Gold coating

A coated carbide grade such as Tiger‑tec Gold extends the service life of the insert by improving wear resistance and thermal stability during steel turning. The WPP30G grade is designed for the heat and chip characteristics typical of ISO P materials, which translates into fewer tool changes and longer productive tool life. For production environments where cycle time and predictable performance matter, this coating technology helps maintain edge integrity and reduces the frequency of interruptions for tool replacement.

Controlled chip formation for safer, cleaner turning

The MP3 chipbreaker is engineered to deliver fragmented, controllable chips when machining steel, lowering the risk of long swarf and improving operator safety. Combined with the rhombic 80° geometry and a 0.8 mm corner radius, the insert produces stable cutting forces and improved surface finishes under varying cutting conditions. This combination reduces vibration and supports consistent part quality, especially in operations that require repeatable dimensional accuracy.

Application-focused design for steel machining (ISO P)

Specifically targeted at steel applications, the grade and geometry are tailored for both unalloyed and alloyed steels commonly encountered in workshop and production settings. The material designation for this insert indicates suitability for ISO P groups, which means the cutting edge and chip control have been optimised for the thermal loads and deformation behaviour typical of steel. The outcome is reliable metal removal rates and consistent surface integrity across batches.

Practical integration and handling in the production cell

The insert designation breaks down into a familiar CNMG form factor with an inscribed circle size code of 12 and a plate thickness code of 04, making it compatible with a wide range of standard CNMG toolholders. The 0° negative rake specification supports stable cutting in heavier passes, while the tolerance class M ensures dimensional conformity for repeatable clamping and indexation.

FAQ

What materials is this insert suitable for?
The CNMG120408-MP3 WPP30G insert is formulated for machining steel (ISO P); the Walter Tools grade WPP30G is optimised for common unalloyed and alloyed steels.

How does the MP3 chipbreaker improve machining?
The MP3 chipbreaker produces short, controlled chips in steel turning, aiding chip evacuation and reducing the chance of long swarf, which improves safety and surface quality.

What does the 0° negative rake mean for cutting?
A 0° negative rake provides a robust cutting edge that withstands higher cutting forces, offering stability during heavier cuts and enhancing edge life for demanding turning operations.
