WNMG080408-MW5 WPP20G Walter Tools – Indexable turning insert with Tiger·tec Gold coating and MW5 chipbreaker

The WNMG080408-MW5 WPP20G is an indexable turning insert designed for machining steel in general turning applications, offering a balance of wear resistance and process stability.

• Tiger·tec Gold coating for consistent edge life
• Optimised MW5 chipbreaker for steel turning
• Trigon 80° geometry for cutting stability
• 0.8 mm corner radius with 0° negative clearance

Faster, more consistent machining through coated carbide technology

The combination of the Tiger·tec Gold coating and the WPP20G grade delivers measurable improvements in tool life and process reliability when cutting steels. The coated carbide substrate is engineered to withstand the typical temperatures and load cycles of steel turning, which translates into fewer insert changes and longer uninterrupted run times. This performance is particularly relevant in medium-duty production where consistent surface quality and predictable tool consumption are priorities.

Reduced downtime thanks to optimised chip formation and stable geometry

The MW5 chipbreaker, paired with the Trigon 80° format, promotes controllable chip formation and stable cutting forces, reducing the risk of interruptions from tangled or long chips. The 0° (negative) clearance increases robustness for interrupted cuts and tougher operations, allowing higher feed rates without sacrificing stability. Together these features support a smoother process window and reduced machine downtime for shops focused on throughput.

Clear application guidance for reliable process planning

Relevant technical markers are provided for planning: size 08, thickness 04, corner radius 0.8 mm, and tolerance class M. The insert is classified for ISO group P, meaning it is suitable for a wide range of unalloyed and alloyed steels where good wear resistance and stable chip control are required. Selection of this geometry and grade is appropriate for a mix of finishing and semi-finishing operations where a balance between edge life and surface finish is sought.
