WNMG060404-MM5 WMP20G indexable turning insert for stainless steel — Walter Tools

The WNMG060404-MM5 WMP20G is an indexable turning insert designed for reliable performance in stainless steel machining, combining Trigon 80° geometry with a 0° negative rake for robust cutting under medium to heavy conditions.

• Tiger·tec Gold coating for extended tool life
• MM5 chipbreaker for secure chip control
• Trigon 80° geometry for stable turning performance
• 0° negative rake suitable for robust cuts

Consistent chip control for uninterrupted production

The Trigon 80° form and the MM5 chipbreaker work together to provide predictable chip formation when working with stainless steel (ISO group M). The chipbreaker is engineered to break swarf into manageable lengths, reducing the risk of entanglement and improving machine uptime. This results in fewer interruptions for chip clearing and a more continuous production flow, which is particularly beneficial in shops focusing on batch turning or heavier engagement cuts. The mechanical stability of the triangular geometry also supports repeatable setup and consistent component quality.

Geometry and cutting angle that support robust machining

The insert’s 0° negative rake and its specified corner radius of 0.4 mm offer a balance between edge strength and cutting forces. A negative rake increases the effective cutting edge robustness, making the insert well suited to medium to robust turning operations where built-up edge and thermal load are concerns. The 0.4 mm corner radius enhances edge durability and helps to maintain surface integrity on demanding stainless steel components, while the Trigon 80° platform provides access and stability on shoulders and interrupted cuts.

Coating and material pairing for improved tool life

The Tiger·tec Gold coating delivers thermal resistance and improved wear characteristics under the high temperatures typically generated when machining stainless steel. Coating technology in this series is aimed at reducing adhesive wear and preserving a stable cutting edge, which translates into longer tool life and fewer indexings. Combined with the solid carbide substrate in the Walter grade, the insert supports consistent surface finishes and repeatable tolerances in production environments where tool-change intervals and process stability matter most.

Practical benefits for daily workshop use

For practical shop-floor application, the insert’s format and chip control reduce manual handling and minimise downtime caused by poor swarf control. The Trigon geometry facilitates secure clamping in most standard toolholders for WNMG-style inserts, making integration into existing toolsets straightforward. Shops processing stainless steel under mixed cutting conditions will find the combination of Tiger·tec Gold and the MM5 chipbreaker particularly useful for maintaining throughput without sacrificing component quality.
