CNMG120408-MP3 WPP20G indexable turning insert, Tiger‑tec Gold coating, for steel — Walter Tools

A CNMG120408-MP3 WPP20G indexable turning insert designed for robust material removal in steel machining, combining a Tiger‑tec Gold coating with an MP3 chipbreaker for consistent chip formation.

• Tiger‑tec Gold coating for extended life
• Optimised MP3 chip control for reliable machining
• Suitable for a wide range of steel grades
• Rhombus 80° shape with 0.8 mm corner radius

Increased productivity through optimised coating and grade

The Tiger‑tec Gold coating together with the WPP20G grade provides a wear‑resistant cutting edge that supports sustained production runs on steel. This combination reduces flank wear and helps maintain dimensional stability over extended cycles, which translates directly into fewer tool changes and higher machine uptime. The coated carbide substrate resists thermal and abrasive damage typical for P‑group machining, so cycle times can be more consistent and predictable.

Reliable chip control and surface quality

Equipped with an MP3 chipbreaker, this insert ensures reliable chip formation during medium to heavy turning. The chipformer geometry prevents entanglement and supports effective evacuation, reducing the risk of rework and machine interruptions. Stable chip flow also contributes to a consistent workpiece finish, making it easier to achieve repeatable tolerances and minimise secondary operations.

Application clarity and compatibility in workshop use

The Rhombus 80° profile and 0.8 mm corner radius combine to offer a balance between edge strength and fine detail capability, suitable for a broad spectrum of steel grades as defined for P‑group materials. The insert’s 0° clearance (negative) configuration provides a secure cutting edge under heavy loads and supports reliable, repeatable turning. Selection of this insert is appropriate where a productive, general‑purpose solution for steel is required, with proven performance across diverse machining tasks.
