CNMG120412-FP5 WPP10G turning insert — Rhombic 80°, 1.2 mm radius, Tiger·tec Gold by Walter Tools

The CNMG120412-FP5 WPP10G is a rhombic 80° indexable turning insert designed for reliable steel machining in demanding production environments.

• Tiger·tec Gold coating for extended tool life
• Designed for steel machining (ISO P)
• 0° negative rake for robust cutting
• 1.2 mm corner radius for stable edge control

Consistent performance for steel machining

The insert delivers high productivity by combining the WPP10G coated grade with the proven geometry of a rhombic 80° insert. The Tiger·tec Gold technology increases wear resistance and thermal stability, which translates into longer tool life and fewer tool changes during batch runs. For operations on ISO P materials, this means more consistent cycle times and reduced tooling costs per component. The coated carbide substrate reduces flank wear in continuous turning and supports predictable tool-change intervals, making the insert a pragmatic choice for serial production and roughing-to-finishing sequences.

Stable cutting edge and effective chip control

Edge stability is ensured by the 1.2 mm corner radius and the FP5 chipbreaker, which together produce controlled chip formation and promote safe evacuation of swarf. The 0° negative rake design provides a robust cutting edge that tolerates heavier depths of cut and intermittent engagement without sacrificing edge integrity. In practice, the geometry reduces vibration and improves surface integrity on turned parts, while the chipbreaker profile helps avoid long, stringy chips that can foul tooling or workpiece fixtures. For operators requiring reliable edge behaviour under varied cutting parameters, this combination enhances process security and repeatability.

Practical application notes and economical use

The insert is supplied in the CNMG120412 format with a nominal size 12 and plate thickness 4 mm, making it compatible with a wide range of standard toolholders. Its execution "G" and FP5 chip control suit turning operations on both roughing and medium-finishing passes in steel. As a coated carbide grade for P-group materials, the insert performs best with cutting fluids in heavy-duty cutting or dry machining in moderate feeds; adapt speeds to workpiece grade and tool life targets. Using these inserts in series production can reduce overall tooling spend through fewer indexings and longer runtimes, supporting both processing efficiency and predictable output quality.

FAQ

What materials is this insert optimised for?
The CNMG120412-FP5 WPP10G is optimised for steel machining and is specified for ISO P materials; the WPP10G grade is tuned for typical heat and chip formation of steel.

How does the FP5 chipbreaker influence machining?
The FP5 chipbreaker promotes controlled chip formation and evacuation, improving process reliability and reducing the risk of chip-related interruptions during turning.

Is the 0° negative rake suitable for interrupted cuts?
Yes, the 0° negative rake provides a robust cutting edge that tolerates interrupted cuts and heavier engagement without rapid edge degradation.

What are the advantages of the Tiger·tec Gold grade?
Tiger·tec Gold offers enhanced wear resistance and thermal stability, which extends tool life and supports consistent component quality in continuous production.

Which toolholder format fits this insert?
The insert corresponds to the CNMG120412 format and fits standard holders designed for CNMG inserts; check holder compatibility with a 12-size insert and 4 mm plate thickness.
