TNMG220408-MS3 WPP20G — Triangular indexable turning insert, Tiger·tec Gold (Walter Tools)

A TNMG220408-MS3 WPP20G insert designed for robust external turning of steel, offering controlled chip formation and extended tool life in medium to high-volume turning applications

• Tiger·tec Gold coating for extended tool life
• WPP20G grade optimised for steel
• Triangle 60° insert with 0.8 mm corner radius
• MS3 chipbreaker for dependable chip control

Consistent performance for steel turning operations

The combination of the WPP20G grade and the Tiger·tec Gold coating delivers a balance of wear resistance and toughness tailored to steel machining (material group P). This results in predictable tool life and fewer tool changes, which directly reduces downtime and increases throughput. The insert’s negative 0° rake geometry stabilises cutting forces during interrupted cuts, while the 0.8 mm corner radius supports reliable edge strength for roughing and medium finishing passes. By specifying this grade, production planners can expect repeatable results across batches, improving process planning and costing.

Reliable chip control and surface finish with MS3 geometry

The MS3 chipbreaker is designed to form short, controllable chips when machining steels, reducing the risk of entanglement and improving evacuation in automated turning cells. Better chip control translates into less secondary handling and fewer surface defects, which helps to maintain consistent surface quality and reduces rework. The triangular 60° shape delivers three cutting edges per indexable insert, supporting economical edge usage and simple indexing procedures in systematic tool change routines.

Process security, repeatability and productivity gains

Built for everyday production environments, this insert supports high process security through stable edge behaviour and temperature-resistant coating technology. The Tiger·tec Gold system offers thermal and mechanical load resistance, enabling higher cutting parameters where the machine and workholding permit, and therefore a potential increase in metal removal rates. The modest insert thickness and standard geometries allow compatibility with a wide range of toolholders, simplifying tool inventory management and promoting faster set-ups across different turning machines.

Practical benefits for workshop and production planning

Using this insert contributes to lower operating costs by extending edge life and reducing the frequency of insert changes. Fewer tool interventions mean more productive spindle time and improved OEE figures. In addition, the straightforward chip control and stable cutting behaviour reduce the need for specialist operator intervention, supporting training efficiency and consistent output quality in both manual and automated turning operations.

FAQ

What materials is this insert intended for?
The TNMG220408-MS3 WPP20G insert is optimised for steel (material group P) and is designed to handle the heat and chip behaviour typical of unalloyed and alloyed steels.

How does the Tiger·tec Gold coating benefit production?
The Tiger·tec Gold coating enhances wear resistance and thermal stability, enabling higher cutting speeds and longer edge life with improved process security when using the WPP20G grade.

Which chipbreaker should be selected for reliable evacuation?
The MS3 chipbreaker integrated in this insert provides controlled short-chip formation for turning steels, improving chip evacuation in both manual and automated operations.

What does the 0° negative rake mean in practice?
A 0° (negative) rake increases edge robustness and resistance to impact, which is advantageous for interrupted cuts or roughing passes where stability and tool life are priorities.

Is this insert compatible with standard TNMG toolholders?
The insert follows the TNMG geometry and fits standard TNMG toolholders; ensure correct clamping and seating per the toolholder manufacturer’s instructions for optimal performance.
