CNMG120408-FW5 WPP20G turning insert — Tiger·tec Gold grade for steel | Walter Tools

CNMG120408-FW5 WPP20G is a rhombic 80° turning insert designed for robust steel machining with an FW5 chipbreaker and a 0.8 mm corner radius

• Tiger·tec Gold coating for extended tool life
• FW5 chipbreaker optimised for steel machining
• Rhombic 80° form for secure seating
• 0.8 mm corner radius for robust cuts

Increase throughput with a coating engineered for wear resistance

The combination of the Tiger·tec Gold technology and the WPP20G grade yields a coated cemented carbide that is tailored to the thermal and mechanical demands of ISO P materials. This results in improved wear resistance and consistent edge stability, which translates into longer tool life and fewer tool changes. For production lines where uptime matters, the coated grade supports predictable tool change intervals and helps to maintain batch quality across long runs.

Achieve stable cutting and reliable edge strength

The rhombic 80° geometry together with a 0° negative rake provides a robust cutting edge for interrupted cuts and heavy engagement. The 0.8 mm corner radius increases edge strength and reduces the likelihood of micro-chipping under shock loads. As a result, holders with secure clamping obtain a stable cutting process and a consistent surface finish on turned components. The insert’s design supports repeatable seating and minimal vibration when paired with appropriate toolholders.

Better chip control and process economy in steel turning

The FW5 chipbreaker is optimised for steel applications, promoting controlled chip formation and evacuation at typical cutting parameters for ISO P materials. Controlled chips reduce tool nose wear and help to avoid rework or machine stoppages, contributing to a lower cost per part. The grade’s balance of toughness and wear resistance makes it suitable for a wide range of unalloyed and alloyed steels, supporting efficient machining strategies and predictable productivity gains.

Practical advantages for workshop integration

The insert designation aligns with common CNMG toolholder systems and fits standard toolposts designed for rhombic 80° geometry. Marked with tolerance class M, the insert meets industrial expectations for interchangeability and repeatable seating. For workshops seeking straightforward upgrades to existing turning processes, this insert offers a pragmatic mix of process reliability, manageable tool costs and broad applicability across steel grades.

FAQ

What steels is this insert suitable for?
The CNMG120408-FW5 WPP20G turning insert is intended for ISO P materials and is suitable for both unalloyed and alloyed steels, offering a balance of wear resistance and toughness for typical steel turning tasks.

How does the FW5 chipbreaker improve the machining process?
The FW5 chipbreaker on the WPP20G grade controls chip formation during steel machining, which aids evacuation, reduces tool nose wear and helps maintain consistent surface quality.

What advantages does the Tiger·tec Gold coating provide?
Tiger·tec Gold, applied to the WPP20G grade, enhances resistance to abrasive wear and extends edge life under the thermal loads common in steel turning operations, resulting in fewer tool changes and improved process stability.

Is the negative 0° rake suitable for interrupted cuts?
Yes. The 0° negative rake combined with the rhombic 80° form and a 0.8 mm corner radius gives the insert a robust edge that performs well in interrupted or heavy engagement cutting scenarios.
