CNMG120412-MP5 WPP20G turning insert — Tiger-tec Gold, MP5 chipbreaker (Walter Tools)

A CNMG120412-MP5 WPP20G indexable turning insert engineered for steel turning applications, combining a Tiger-tec Gold coated carbide grade with MP5 chip control for stable, repeatable machining.

• Tiger-tec Gold coating for extended tool life
• MP5 chipbreaker for reliable chip control
• Rhombic 80° geometry for versatile turning
• Designed specifically for machining steel

Productivity through advanced coating and grade

The combination of the Tiger-tec Gold coating and the WPP20G grade delivers a balance of wear resistance and toughness that supports longer tool life and fewer insert changes. Coated carbide technology improves thermal stability and edge integrity under the cyclic loads typical in steel turning, which translates into measurable productivity gains and reduced downtime. The specification targets process reliability and cost efficiency in daily turning operations, especially where consistent surface finish and repeatable performance are required.

Improved chip control and secure cutting edge

Equipped with the MP5 chipbreaker and a 1.2 mm corner radius, this insert ensures predictable chip formation and evacuation in ISO P materials (steel). The MP5 geometry is designed to break and guide chips effectively during medium to general-purpose turning, reducing risk of entanglement and machine interruptions. The Rhombus 80° form and the 0° (negative) rake angle provide a robust seating and a stiff cutting edge, helping to maintain dimensional accuracy and surface quality in continuous and interrupted cuts.

Versatility and straightforward integration into existing toolholders

The CNMG format offers broad compatibility with standard CNMG toolholders, while the plate size (12) and thickness code (04) align with common turning setups. As a coated, indexable insert of the Tiger-tec Gold series, the design supports a wide range of steel grades and typical feed/speed windows encountered in production and repair shops. The product combines the mechanical advantages of a rhombic insert with a coating and substrate tuned for steel machining, delivering both process security and practical handling benefits for workshop routines.

FAQ

What materials is this insert suitable for?
The CNMG120412-MP5 WPP20G insert is specified for ISO P materials and is particularly suited to machining various steels owing to its WPP20G Tiger-tec Gold coated carbide grade.

How does the MP5 chipbreaker affect machining?
The MP5 chipbreaker on the CNMG120412-MP5 promotes controlled chip formation and evacuation, which helps to reduce interruptions and improves process reliability during turning operations in steel.

Can this insert be used for interrupted cuts?
Yes, the rhombic 80° geometry together with the negative 0° rake and the robust WPP20G substrate provide a stable cutting edge suitable for many interrupted and continuous turning applications.

What is the corner radius and why does it matter?
This insert has a 1.2 mm corner radius; a larger radius increases edge strength and improves surface finish potential but requires attention to tool path programming to avoid radius-related dimensional deviations.
