WNMG080408-MM5 WMP20G indexable turning insert — Tiger·tec Gold coating for stainless steel | Walter Tools

WNMG080408-MM5 WMP20G is an indexable turning insert designed to deliver stable cutting performance in stainless steel applications thanks to a Tiger·tec Gold coating and an MM5 chipbreaker

• Tiger·tec Gold coating for enhanced wear resistance
• Trigon 80° shape for stable heavy cuts
• 0.8 mm corner radius for consistent edge strength
• Optimised for machining stainless steel (ISO M)

High-performance coating for consistent machining results

The insert is equipped with the Tiger·tec Gold technology, a multilayer coating system developed to maintain a stable cutting edge under the elevated temperatures and adhesion tendencies typical of stainless steel. This coating reduces flank wear and supports repeatable process windows, which translates into fewer tool changes and higher overall productivity. Combined with the MM5 chipbreaker, the insert promotes secure chip formation and evacuation, lowering the risk of built-up edge and improving surface finish on demanding materials.

Geometry engineered for rigidity and cutting reliability

A Trigon 80° plate form provides a large cutting edge and improved insert support, making the design particularly suitable for medium to robust turning operations where stability is essential. The 0.8 mm corner radius increases edge strength and resists edge chipping during interrupted cuts, while the 0° (negative) rake angle contributes to a robust cutting geometry that tolerates higher cutting forces. These geometric choices result in reliable performance and predictable tool life when integrated into standard turning holders.

Practical benefits: process security and shop-floor efficiency

Using an indexable solution such as this trigon insert reduces setup time and tool inventory complexity. The standardised WNMG designation facilitates quick replacement and straightforward toolholder selection. For assemblies that require predictable output and easy indexability, this insert supports efficient cycle times and reduced downtime.

FAQ

What materials is this insert designed for?
The WNMG080408-MM5 WMP20G insert is optimised for stainless steel (ISO group M) and supports secure chip formation and stable cutting edges in those applications.

How does the MM5 chipbreaker affect machining of stainless steels?
The MM5 chipbreaker on the WNMG080408-MM5 promotes controlled chip segmentation and evacuation, reducing the tendency for built-up edge and improving surface quality when turning stainless steel.

Is the Trigon 80° shape suitable for heavy cuts?
Yes, the Trigon 80° geometry provides a large engagement face and good support in the toolholder, which enhances rigidity and makes the insert appropriate for medium to robust cutting operations.

What benefit does the Tiger·tec Gold coating deliver?
The Tiger·tec Gold coating extends tool life by reducing flank wear and improving heat resistance, helping to maintain consistent cutting performance on challenging stainless steel grades.

Can this insert be indexable in standard WNMG toolholders?
The WNMG080408-MM5 WMP20G follows the standard WNMG designation and is compatible with corresponding toolholders designed for WNMG inserts, enabling quick indexing and replacement
