DCMT11T308-RP4 WPP20G indexable turning insert — Tiger·tec Gold, for steel — Walter Tools

A DCMT11T308-RP4 WPP20G indexable turning insert engineered for reliable steel turning with a rhombic 55° geometry and optimised chip control

• Tiger·tec Gold coating for enhanced wear resistance
• Optimised RP4 chipbreaker for reliable chip control
• Rhombic 55° geometry for versatile turning operations
• Corner radius 0.8 mm for robust cutting edges

Longer tool life through advanced coating technology

The insert is equipped with Tiger·tec Gold, a high-performance coating designed to extend tool life under the thermal and mechanical demands of machining steel. The coating’s combination of thermal stability and low friction reduces flank wear and minimizes adhesion, which leads to fewer interruptions for tool changes and higher process efficiency. For production environments, this results in improved productivity and predictable tool consumption, supporting leaner planning and reduced tooling costs.

Stable chip formation and improved surface quality

An optimised RP4 chipbreaker delivers consistent chip shaping and evacuation when machining steels, reducing the risk of built-up edge and erratic cutting forces. Stable chips protect the component surface and the machine spindle, contributing to a more consistent surface finish and reduced rework. The chip geometry favours continuous, controllable chips in common steel grades, supporting higher cutting data and better process security in series production.

Geometry that balances reach and edge strength

The rhombic 55° insert form and a relief angle of 7° enable a versatile approach to external turning tasks while maintaining cutting-edge strength. The corner radius 0.8 mm provides a compromise between edge robustness and fine surface generation, suitable for general-purpose turning and finishing passes. The insert’s size 11 and T3 thickness contribute to sturdy clamping and reliable repeatability, especially under moderate to demanding cutting conditions.

Designed for reliable steel machining and simple integration

Classified for the material group P (steel) and made from a coated carbide grade, the insert supports a broad range of unalloyed and alloyed steels per ISO 513 recommendations. The tolerance class M ensures consistent geometry across batches, aiding predictable setup and reducing adjustment time at the turret. As a standardized indexable solution, this insert integrates into common toolholders and is suitable for workshops aiming for reproducible process results and efficient tool management.
