TNMG220412-RP5 WPP05G Drehwendeschneidplatte — Tiger‑tec Gold, for steel | Walter Tools

The TNMG220412-RP5 WPP05G is a triangular 60° indexable insert designed for productive external turning of steel, offering a coated‑carbide grade optimised for wear resistance and consistent chip formation.

• Tiger‑tec Gold coating for long tool life
• RP5 chipbreaker for controlled chips
• Triangular 60° geometry, 1.2 mm corner radius
• Negative 0° rake for robust cutting edge

Greater uptime through advanced coating and grade selection

The combination of the Tiger‑tec Gold coating and the WPP05G grade yields a coated carbide solution developed for machining steel (material group P). The multilayer coating improves resistance to abrasive and adhesive wear, which extends tool life and reduces tool changes in high‑volume production. For process planners this means a lower cost per component and fewer unscheduled interruptions: the coating acts as a thermal and chemical barrier at the cutting edge, slowing degradation during typical turning conditions.

Consistent chip control and a stronger cutting edge for tougher cuts

The insert’s RP5 chipbreaker is engineered to produce short, manageable chips when cutting steels, improving evacuation and surface quality. The negative 0° rake increases edge strength and reduces edge chipping under interrupted or heavy cuts, while the triangular 60° geometry and corner radius 1.2 mm balance strength and edge accessibility. For shops transitioning from general‑purpose grades, these geometric choices mean improved reliability when facing varying feed rates and depths of cut.

Practical compatibility and process benefits for production

Marked tolerance class M and the proven series construction allow straightforward integration into standard toolholders for turning operations. The insert’s specification targets universal steel machining needs, supporting both roughing and general finishing when set up with appropriate cuts. For procurement and planning teams, the result is a compact inventory solution: one grade that covers a broad range of steel grades with stable performance, reducing the need for multiple specialised inserts.

FAQ

What steels is this insert designed for?
The TNMG220412‑RP5 WPP05G is specified for material group P, which covers unalloyed and alloyed steels; the WPP05G grade and Tiger‑tec Gold coating are tuned for typical steel cutting temperatures and chip formation.

How does the negative 0° rake affect cutting?
A negative 0° rake on this indexable insert increases the cutting edge strength and improves resistance to mechanical shock; the TNMG220412‑RP5 with RP5 chipbreaker is therefore suitable for heavier and interrupted cuts.

Can this insert be used for finishing operations?
Yes — with appropriate feeds and speeds the insert provides acceptable surface quality for general finishing, benefiting from the coated carbide grade for consistent performance.

What is the role of the RP5 chipbreaker?
The RP5 chipbreaker on the TNMG220412‑RP5 WPP05G promotes short, controllable chips when machining steel, aiding chip evacuation and reducing the risk of surface damage.
