CNMG120412-RP5 WPP20G indexable turning insert — Tiger·tec Gold coated, for steel — Walter Tools

A CNMG120412-RP5 WPP20G indexable turning insert designed for stable, high-productivity steel turning with a controlled-chip RP5 geometry and a robust 1.2 mm corner radius.

• Tiger·tec Gold coated for longer tool life
• RP5 chipbreaker for controlled chip formation
• Negative 0° geometry for stable heavy cuts
• 1.2 mm corner radius for robust edge strength

Increased productivity for steel turning operations

The combination of a Tiger·tec Gold coating and the WPP20G carbide grade is engineered to extend cutting-edge life while maintaining consistent performance on steels (ISO group P). The advanced coating reduces flank wear and helps to preserve cutting-edge geometry under heat and load, which translates into fewer index changes and higher component throughput. Designed for applications where cycle time and repeatability matter, this insert supports sustained, efficient machining and predictable tool-change intervals.

Predictable chip control and dependable cutting stability

The integrated RP5 chipbreaker and the negative 0° geometry deliver controlled chip formation and high process stability when facing interrupted cuts or heavy-depth turning. The 1.2 mm corner radius strengthens the cutting edge against mechanical and thermal shock, improving resistance to chipping and enabling reliable roughing cycles. With a rhombic 80° shape and tolerance class M, this insert provides a balance between accessibility to profiles and consistent seating in compatible toolholders.

Ease of selection and practical application advice

Available in size 12 with thickness designation 04, this insert addresses a broad range of general steel machining tasks and suits standard turning toolholders designed for CNMG-style inserts. The WPP20G grade targets steel workpieces with typical heat and chip behaviours and is a universal choice for many shop-floor conditions. For specific cutting parameters, holder compatibility or optimisation for particular steels, Metav Werkzeuge’s technical consultants can provide tailored recommendations to maximise tool life and surface quality.

FAQ

What materials is this insert suited for?
The CNMG120412-RP5 WPP20G insert is formulated for machining steels (ISO group P) and the WPP20G grade is optimised for typical steel heat and chip formation.

How does the RP5 chipbreaker affect performance?
The RP5 chipbreaker on the Walter Tools insert produces short, controllable chips for safer swarf handling and consistent surface finish while supporting robust metal removal rates.

Is the insert suitable for heavy roughing cuts?
Yes; the negative 0° geometry combined with the 1.2 mm corner radius gives enhanced edge strength and stability for heavy or interrupted cuts in steel.

Which toolholders are compatible with CNMG120412-RP5 inserts?
Standard toolholders for CNMG-shaped indexable inserts are compatible; ensure the pocket and clamping match the rhombic 80° geometry and tolerance class M for secure seating.

Can Metav Werkzeuge advise on cutting parameters?
Metav Werkzeuge provides application support and can recommend cutting speeds, feeds and depths tailored to the workpiece material and machining strategy for best results with this Walter Tools insert.
