CNMG120412-MP3 WPP05G indexable turning insert — Tiger‑tec Gold for Stahl

The CNMG120412-MP3 WPP05G is an indexable turning insert engineered for high-performance Stahl machining, offering a coated-carbide grade optimised for versatile production turning.

• Tiger‑tec Gold coating for extended tool life
• Optimised MP3 chipbreaker for controlled chips
• Rhombic 80° shape with 1.2 mm nose radius
• Negative 0° rake for stable interrupted cuts

Reliable performance and extended lifetime through advanced coating

The combination of Tiger‑tec Gold technology and the WPP05G coated-carbide grade gives this insert a clear productivity advantage in continuous production. The coated carbide substrate, developed for common turning temperatures and chip formation in Stahl, reduces wear and extends edge life, which in turn lowers tool-change frequency and downtime. The MP3 chipbreaker is engineered to produce short, manageable chips under typical turning feeds, improving cycle times and shop-floor safety while delivering consistent surface finish.

Stable cutting geometry for predictable results and easy process set-up

The Rhombic 80° geometry and 1.2 mm nose radius provide a balanced mix of strength and finish capability: the larger corner radius supports heavier engagement and improves edge stability, while the geometry enables reliable approach angles across a range of depths of cut. The negative 0° rake increases resistance to chipping in interrupted cuts and hard spots, which is particularly valuable in mixed-batch production where material variability can occur. Together, these features help achieve repeatable tolerances and reduce scrap rates.

Practical advantages for production turning and tool management

Designed for machining Stahl according to ISO group P, this insert suits a wide spectrum of unalloyed and alloyed steels and is available in the CNMG120412-MP3 format for straightforward integration into standard turning tool holders. The MP3 chip control reduces manual handling and improves machinist confidence during longer cycles. Walter Tools’ manufacturing standards support predictable wear patterns and process security, making this insert a pragmatic choice for workshops seeking stable throughput and reduced lifecycle costs.

FAQ

Which materials is this insert suitable for?
The CNMG120412-MP3 WPP05G insert is specified for materials in group P and is therefore intended primarily for machining Stahl in a wide range of grades.

How does the MP3 chipbreaker affect production?
The MP3 chipbreaker on the CNMG120412-MP3 WPP05G promotes controlled chip form, which reduces operator intervention and supports uninterrupted production cycles.

Is this insert suitable for interrupted cuts?
Yes, the negative 0° rake and robust geometry make the CNMG120412-MP3 WPP05G resilient in interrupted turning and situations with variable material consistency.

What benefits does the Tiger‑tec Gold coating provide?
Tiger‑tec Gold on the WPP05G grade improves wear resistance and thermal stability, enabling longer tool life and more consistent results across extended runs.

Can this insert be used in standard CNMG tool holders?
The CNMG120412-MP3 format is compatible with standard tool holders designed for CNMG inserts; correct clamping and seat condition should be checked before use.
