TNMG160408-MU5 WPP20G indexable turning insert (Tiger·tec Gold) by Walter Tools

TNMG160408-MU5 WPP20G is an indexable turning insert designed for reliable steel machining in industrial turning applications

*Tiger·tec Gold coating for extended tool life
*MU5 chipbreaker optimised for steel machining
*Triangle 60° insert, 0.8 mm corner radius
*Negative 0° rake for stable cutting

High wear resistance for demanding steel operations

The TNMG160408-MU5 WPP20G combines a modern Tiger·tec Gold coating with a coated carbide substrate to deliver outstanding resistance to flank and crater wear during continuous turning of steel. The WPP20G grade is developed for the thermal and mechanical conditions typical of steel machining and offers a balanced mix of hardness and toughness for long tool life. For production environments seeking lower tooling costs per part, this grade supports sustained performance across varying feed rates and depths of cut without premature edge failure.

Geometry crafted for dependable chip formation and surface finish

The triangular 60° shape together with the MU5 chipbreaker produces a controlled chip flow that reduces vibration and improves surface integrity. The defined 0.8 mm corner radius provides a robust cutting edge that helps avoid micro-chipping when interrupted cuts occur, while the negative 0° rake angle increases edge stability for heavy or roughing passes. These geometrical choices result in repeatable part quality and predictable tool behaviour, simplifying process planning and reducing scrap rates.

Increased process security and economical machining

Using a grade optimised for steel means fewer unexpected tool changes and more consistent cycle times. The coated substrate of the insert reduces adhesive wear and increases resistance to built-up edge formation, which in turn maintains dimensional accuracy over longer tool life. Stability of the cutting edge and the insert’s tolerance class M ensure reliable positioning in standard indexable holders, supporting higher uptime and lower unit costs — measurable benefits for batch production and continuous turning lines.

Application guidance and compatible setups

This insert is suited to general turning applications on unalloyed and alloyed steels in accordance with ISO P material groups. The combination of the MU5 chipbreaker and triangular 60° form is particularly effective for medium to heavy cuts where chip control and edge robustness are priorities. The insert is compatible with standard TNMG toolholders; selection of appropriate clamping torque and holder rigidity will preserve the insert’s performance and contribute to stable cutting conditions. For tailored recommendations, material-specific feeds and speeds can be provided by Metav Werkzeuge’s technical team.

FAQ

What materials is this insert suitable for?
The TNMG160408-MU5 WPP20G insert is formulated for machining steel (ISO P); the WPP20G grade and Tiger·tec Gold technology are optimised for the thermal and chip-forming characteristics of steel.

How does the MU5 chipbreaker influence performance?
The MU5 chipbreaker promotes controlled chip formation and evacuation in turning operations, improving surface quality and reducing the risk of built-up edge when machining steel.

What does the 0.8 mm corner radius mean for cutting?
A 0.8 mm corner radius increases edge strength and resistance to chipping, making the insert suitable for interrupted cuts and applications where a robust cutting edge is required.

Is this insert compatible with standard TNMG toolholders?
Yes, the insert conforms to the TNMG form and tolerance class M, and is compatible with standard toolholders designed for TNMG inserts; correct clamping and holder rigidity are essential for best results.

Can this grade be used for finishing passes?
While the insert performs well across a range of cuts, the WPP20G grade provides a balance of wear resistance and toughness suitable for both roughing and medium finishing on steel; final fine finishing may benefit from a smaller corner radius or a grade explicitly tuned for fine surface finish.
