CNMG120408-MP5 WPP20G — Drehwendeschneidplatte (for steel) by Walter Tools, Tiger·tec Gold coating, MP5 chipbreaker

A CNMG120408-MP5 WPP20G rhombic 80° turning insert designed for efficient steel machining, offering coated carbide performance and a stable cutting geometry for general turning applications

• Tiger·tec Gold coating for long tool life
• Optimised MP5 chipbreaker for controlled chips
• Rhombic 80° geometry for stable cuts
• 0.8 mm corner radius for robust edges

Consistent wear resistance for demanding steel operations

The combination of the Tiger·tec Gold coating and the WPP20G grade delivers a marked improvement in wear resistance for steel applications. Coated carbide technology provides a protective layer that reduces abrasive wear and maintains a sharp cutting edge, which translates into extended tool life and fewer insert changes. For operations that generate significant cutting heat, this coating helps to stabilise edge condition and supports repeatable machining results. As a consequence, cycle times remain predictable and tool costs per component are reduced while maintaining component tolerances.

Reliable chip control and geometry that stabilises cutting forces

The integrated MP5 chipbreaker and the Rhombic 80° shape work together to control chip formation and evacuate swarf efficiently. The chipbreaker is engineered to break and curl chips under a wide range of feeds and depths of cut, reducing the risk of entanglement and improving surface quality. The 0° negative rake setting enhances edge strength and contributes to process stability in medium- to heavy-duty cutting. A 0.8 mm corner radius offers robustness at the cutting edge, improving resistance to edge chipping and providing a consistent finish on the machined surface.

Application advantages and process reliability in steel turning

Specifically developed for the machining of steels (ISO group P), this indexable insert suits both unalloyed and alloyed steel grades commonly encountered in production workshops. The grade’s balance between wear resistance and toughness supports versatile use—short-run turning, medium-batch production and general finishing operations. The result is improved process reliability and better reproducibility from one workpiece to the next. For manufacturers seeking predictable outcomes and reduced downtime, the insert’s combination of geometry and coating offers a practical route to enhanced productivity and fewer interruptions for tool change.

FAQ

What materials is this insert intended for?
The CNMG120408-MP5 WPP20G insert is specified for machining steels (ISO group P), covering both unalloyed and alloyed steel grades.

How does the MP5 chipbreaker improve machining?
The MP5 chipbreaker is designed to produce short, controllable chips across a range of feeds, improving swarf evacuation and surface finish while reducing the risk of chip-related issues.

Is the grade suitable for finishing and medium cutting?
Yes; the WPP20G grade balances wear resistance and toughness, making it suitable for finishing and medium cutting operations in steel.

What advantages does the Tiger·tec Gold coating provide?
The Tiger·tec Gold coating enhances wear resistance and thermal stability, extending tool life and supporting consistent edge condition during prolonged cutting.

Can the insert handle interrupted cuts or hard conditions?
The 0.8 mm corner radius and negative rake geometry contribute to edge strength and robustness, increasing resistance to chipping under interrupted or demanding conditions.
