CNMG120412-RP7 WPP20G indexable turning insert — rhombic 80° geometry, Tiger·tec Gold (Walter Tools)

CNMG120412-RP7 WPP20G is a coated carbide indexable insert designed for productive turning of steels with optimised chip control and stable tool life

• Tiger·tec Gold coated carbide WPP20G
• Optimised chipbreaker RP7 for stable chip control
• Rhombic 80° geometry for versatile turning
• 0° negative rake and 1.2 mm nose radius

High productivity through advanced coating and grade

The combination of Tiger·tec Gold coating and the WPP20G grade provides a balance of wear resistance and toughness that is particularly effective in turning operations on steel (ISO P). The coated carbide construction reduces flank and crater wear under typical steel cutting temperatures, which leads to longer tool life and fewer insert changes. This results in measurable productivity gains on medium- to high-duty turning tasks, where stable edge performance is essential for consistent cycle times and process reliability.

Reliable chip control and process stability

Built-in RP7 chipbreaking geometry and the rhombic 80° shape deliver reproducible chip formation and evacuation, helping to prevent edge damage and machine downtime. The 0° negative rake supports robust cutting in interrupted cuts and tougher workpiece conditions, while the 1.2 mm nose radius contributes to repeatable dimensional accuracy and surface finish. These features combine to reduce rework and increase throughput in batch production or mixed-series turning.

Practical fitment and application advantages

The insert’s ISO designation and compact format make it compatible with a wide range of toolholders and clamping systems commonly used in industry. The turnable rhombic form offers four usable cutting corners, improving economy per part. Designed primarily for steel machining, the grade distribution targets a broad spectrum of steels—from wear-resistant to general-purpose applications—offering a single, versatile solution where tool inventory consolidation and predictable performance are priorities.

FAQ

Is this insert suitable for turning steels?
Yes. The CNMG120412-RP7 WPP20G insert is designed for machining steel (ISO P) and the WPP20G grade is optimised for the thermal and chip formation characteristics typical of steel turning.

What benefit does the Tiger·tec Gold coating provide?
The Tiger·tec Gold coating enhances wear resistance and edge stability, which extends insert life under continuous steel machining and improves process reliability for Walter Tools turning inserts.

How does the RP7 chipbreaker affect production?
The RP7 chipbreaker promotes stable chip formation and evacuation, reducing risk of built-up edge and machine stoppages, which supports higher productivity and consistent surface quality.

Can the rhombic 80° geometry be used for shoulder and profile turning?
Yes. The rhombic 80° shape offers a versatile cutting orientation suitable for general turning, shoulder work and varied toolholder arrangements while providing four cutting corners per insert.

What does the 0° negative rake imply for operation?
A 0° negative rake provides a robust cutting edge suited to interrupted cuts and tougher tool engagement, contributing to reliable edge life and stable cutting for demanding turning tasks.
