WNMG100612-MM5 WMP20G Turning insert – Trigon 80°, for stainless steel – Walter Tools

WNMG100612-MM5 WMP20G is a coated turning insert optimised for machining stainless steel under medium to heavy conditions

• Tiger·tec Gold coated grade WMP20G
• Trigon 80° geometry for robust turning
• MM5 chipbreaker for secure chip control
• 1.2 mm corner radius for increased edge strength

Superior grade for demanding stainless-steel turning

The WMP20G grade, part of the Tiger·tec Gold series, is a coated carbide solution developed for machining stainless steel where heat generation and built-up edge are critical. The advanced coating improves thermal stability and wear resistance, which translates into longer intervals between indexings and fewer tool changes. For production environments this yields measurable improvements in uptime and component consistency. The insert’s MM5 chipbreaker supports controlled chip formation in difficult-to-cut alloys, reducing the risk of chip entanglement and promoting secure evacuation.

Geometry built for stability and repeatable edge life

With a Trigon 80° platform and a 1.2 mm corner radius, the geometry prioritises edge strength and resistance to chipping during interrupted cuts or heavy cross-sections. The negative 0° rake angle contributes to a stronger cutting edge and stable cutting forces, which benefits heavier cuts and roughing operations. Corner radius choices influence surface finish and edge robustness: a larger radius increases strength and tool life, while maintaining acceptable surface quality for many turning tasks. This insert’s configuration is therefore suited to operations where repeatable performance and predictable tool wear are required.

Integrating the insert into production for consistent results

Selecting the correct insert grade and geometry is the rational route to improved throughput. The combination of Tiger·tec Gold technology and the MM5 chipbreaker reduces vibration and promotes continuous metal removal with fewer interruptions. For shops transitioning from general-purpose grades, this insert offers higher reliability when machining ferritic, austenitic or duplex stainless steel variants. The tolerance class M and coated substrate provide consistent cutting behaviour across batches, simplifying parameter transfer between machines. For best outcomes, pair the insert with a compatible toolholder designed for WNMG geometry and adjust feed to match the corner radius for desired surface finish.

FAQ

Is this insert suitable for austenitic stainless steels?
Yes. The WNMG100612-MM5 WMP20G turning insert from Walter Tools is designed for stainless steel and performs well on austenitic grades, offering stable chip formation and resistance to built-up edge.

Which chipbreaker is fitted and what is its benefit?
The insert features the MM5 chipbreaker, which promotes secure chip control in tough-to-cut stainless steels and reduces the likelihood of chip-related interruptions in automated turning operations.

What does the Trigon 80° form mean for cutting?
Trigon 80° geometry provides a robust seating and stronger cutting edge, improving resistance to mechanical stresses during roughing and intermittent cutting compared with sharper geometries.

Can this insert be used in existing WNMG toolholders?
Yes. The geometry and ISO designation WNMG100612-MM5 WMP20G conform to standard WNMG toolholder interfaces; pairing with a properly clamped holder is recommended for repeatable results.

How does the Tiger·tec Gold coating affect performance?
The Tiger·tec Gold coating enhances thermal stability and wear resistance, extending cutting edge life and enabling more consistent performance when machining challenging stainless steel grades.
