TCMT090208-RP4 WPP30G indexable insert for steel machining — Walter Tools

The TCMT090208-RP4 WPP30G is a triangular indexable insert engineered for productive turning and drilling-related operations in steel applications, delivering controlled chip formation and extended edge life.

• Tiger·tec Gold coating for wear resistance
• Triangle 60° shape with 0.8 mm corner radius
• Optimised for steel machining (ISO P)

Prolonged edge life through advanced coating technology

The insert features the Tiger·tec Gold coating combined with the WPP30G grade, a coated carbide formulation developed for balanced wear resistance and toughness. This technology stabilises edge wear under the thermal and mechanical loads typical for steel cutting, which translates into longer tool life and fewer indexings. For production environments this means lower tooling costs per component and more consistent batch output, since the coating supports steady cutting performance and improved resistance to abrasive wear.

Geometry that improves reliability and surface quality

With a triangle 60° configuration and a 0.8 mm corner radius, the insert offers excellent edge strength while enabling reliable finishing performance. The modest corner radius increases load-bearing capacity at the cutting edge, reducing chipping risk during interrupted cuts. The specified 7° clearance assists in reducing rubbing and heat transfer to the flank, improving surface integrity. The RP4 chipbreaker promotes predictable chip control, aiding safe swarf removal and reducing the risk of built-up edge. These combined geometric features make the component suitable for stable turning and light finishing passes in industrial workflows.

Clear operational benefits and application fit

Designed for the ISO P material group, this insert supports a wide range of unalloyed and alloyed steel grades commonly encountered in machining shops. The compact size and standard TCMT designation facilitate use with readily available holders, enabling quick replacement and minimal setup time. Operational advantages include more consistent surface finishes, reduced rework due to edge reliability, and improved process security in serial production. For teams seeking both productivity and repeatability, the combination of coating, grade and geometry provides a pragmatic balance between tool life and machining quality.
