WNMG080408-FM5 WMP20G (Indexable turning insert) – Tiger·tec Gold, for stainless steel — Walter Tools

A WNMG080408-FM5 WMP20G indexable turning insert engineered for medium to robust conditions when machining stainless steel, offering coated-carbide durability and stable chip formation

• Tiger·tec Gold coating for durable edge
• Specifically for stainless steel (ISO M)
• Trigon 80° shape for secure clamping
• 0° negative rake with 0.8 mm corner radius

Consistent cutting performance for stainless steel

The WMP20G grade, employed in the Tiger·tec Gold series, is a coated carbide solution optimised for stainless steel. The coating and substrate combination promotes stable chip formation and reduces the tendency for built-up edge under the high heat and toughness typical of these alloys. As a result, predictable cutting behaviour and improved edge life can be expected during continual production runs. This makes the insert suitable for demanding operations that require repeatable surface quality and fewer tool changes, supporting productivity goals without adding process complexity.

Secure geometry for repeatable results

The Trigon 80° plate form combined with a 0° negative rake gives the insert a robust cutting edge and reliable clamping interface. The integrated FM5 chipbreaker is designed to control chips from interrupted or heavy cuts, while the 0.8 mm corner radius balances edge strength with acceptable cutting forces for medium cuts. Together, these features reduce vibration and support stable machining behaviour, which contributes to more consistent part tolerances and less scrap in serial production. Operators benefit from a geometry that tolerates tougher engagement conditions while simplifying tool selection.

Practical advantages for workshop efficiency

Standardised form and grade reduce inventory complexity and ease tool management across multiple lathes. The insert's construction supports longer intervals between indexings and replacements, which lowers downtime and increases machining throughput. In addition to machining performance, the coated grade contributes to improved surface finish on components made from stainless steel, lowering the need for secondary operations.
