Consistent wear protection for longer production runs

The Tiger·tec Gold technology in this insert provides a high-performance, coated carbide substrate that improves thermal stability and wear resistance under the temperatures typical when machining steel (ISO P). This results in fewer tool changes and a steadier machining process, which in turn contributes to predictable cycle times and lower per-part tooling costs. The combination of substrate and coating is engineered to balance toughness and hardness, enabling the insert to withstand interrupted cuts and maintain a stable cutting edge over extended periods.

Predictable chip formation and surface quality

The RP7 chipbreaker is developed to control chips reliably across a range of feeds and depths of cut, reducing the risk of built-up edge and minimising rework. Controlled chip evacuation leads to improved process security and a more consistent surface finish on turned parts. For operations where repeatability matters — such as batch production or precision shafts — the predictable behaviour of this chipbreaker helps to reduce cycle variability and supports tighter tolerances.

Robust geometry for flexible machining strategies

The rhombic 80° shape with 0° rake and a 1.2 mm corner radius offers a versatile balance between edge strength and accessibility for side and face turning. The insert dimensions (designation CNMG120412-RP7) provide a stable mounting and a larger effective cutting edge, which is beneficial when taking heavier cuts or when minor tool deflection must be avoided. The negative rake geometry enhances the insert’s resistance to edge chipping under load, making it suitable for a wide range of steel grades from general-purpose to tougher, more abrasive steels.

Application benefits and production efficiency

Designed specifically for machining steel, the WPP10G grade targets high process reliability and broad material coverage within ISO group P. The insert supports efficient chip control, consistent surface finishes and fewer interruptions for tool changes — all contributing to improved throughput and lower manufacturing costs. For manufacturers seeking stable, reproducible results in turning, this grade and geometry combination offers a sound, cost-effective solution that integrates well into automated and manual turning workflows.
