CNMG120408-MW5 WPP20G turning insert – Tiger·tec Gold, for Stahl | Walter Tools

The CNMG120408-MW5 WPP20G is a rhombic 80° turning insert engineered for general Stahl machining, combining a Tiger·tec Gold coated grade with a robust MW5 chipbreaker for dependable productivity in production turning applications.

• Tiger·tec Gold coated grade WPP20G
• Optimised MW5 chipbreaker
• Rhombic 80° geometry for versatile turning
• 0.8 mm corner radius for robust edge life

High, repeatable performance for Stahl applications

Designed around the WPP20G grade and the Tiger·tec Gold coating, this indexable insert provides enhanced wear resistance and consistent cutting behaviour when machining unalloyed and alloyed Stahl. The coated carbide substrate reduces flank wear and helps maintain a stable cutting edge under moderate to demanding conditions, translating into longer tool cycles and fewer changeovers. For production environments where cycle-time and repeatability matter, this solution supports steady material removal rates and predictable tool life.

Stable chip control and improved surface finish

The integrated MW5 chipbreaker is optimised to produce manageable chips and to lower the risk of built-up edge during continuous turning operations. Coupled with the 0° negative clearance, the geometry reduces vibration and scraping tendencies, resulting in more consistent surface integrity. The 0.8 mm corner radius contributes to edge robustness and makes the insert suitable for light profiling as well as medium roughing passes, balancing productivity with acceptable component finish.

Versatile geometry that simplifies tooling choices

The rhombic 80° form and the CNMG size designation enable flexible deployment across common toolholder systems for turning. The plate’s dimensions and tolerance class M ensure secure clamping and repeatability when indexing corners, aiding batch consistency. Because the insert presents multiple cutting edges, it supports economical use in mixed production: a single tool body can cover a range of operations without frequent tool changes, reducing setup complexity and improving uptime.

Predictable integration into production processes

As a coated carbide turning solution from Walter Tools’ Tiger·tec Gold family, the indexable plate is intended for straightforward integration into standard turning cycles for Stahl. The combination of coating, grade and chipbreaker helps to standardise cutting parameters and shorten process tuning time. For engineering teams seeking to increase productivity while maintaining surface quality, this insert offers a pragmatic balance between wear resistance and toughness, enabling efficient, repeatable machining performance.
