CNMM160612-HU7 WPP30G Turning Insert for Steel — Walter Tools

CNMM160612-HU7 WPP30G is a rhombic 80° indexable insert designed for turning steel, featuring Tiger·tec Gold coated carbide and an HU7 chipbreaker for stable machining performance.

Tiger·tec Gold coating for long tool life Optimised HU7 chipbreaker for stable chips Rhombic 80° geometry for versatile turning Corner radius 1.2 mm for consistent edge strength

Consistent productivity through advanced grade and coating

The Tiger·tec Gold grade WPP30G combines a coated carbide substrate with an optimised microstructure to deliver high wear resistance and repeatable performance when machining steels (material group P). This engineering reduces flank and crater wear under typical turning temperatures, which translates into longer indexable insert life and fewer tool changes. The result is a measurable improvement in machining uptime and predictable tool-cost planning for production environments where cycle time and tool stability matter.

Reliable chip control and surface quality from geometry

The HU7 chipbreaker together with the rhombic 80° form and a 0° (negative) relief produce controlled chip formation across a wide range of feeds and cutting speeds. The 1.2 mm corner radius increases edge strength and supports consistent surface finish on turned components, while the negative rake aids in heavy roughing applications. These geometric properties make the insert suitable for both medium- and heavy-duty turning tasks, improving process security and reducing the likelihood of built-up edge or unpredictable chip behaviour.

Seamless integration and cost-effective operation

Designated as CNMM160612-HU7, the insert fits common ISO toolholder systems for rhombic inserts, enabling quick index changes and straightforward stock management. The combination of coating, grade and geometry allows fewer tool changes and predictable wear progression, supporting lower tooling costs per part. For operations seeking to streamline tool inventories, this insert offers a balance of versatility and economy, particularly when machining a range of unalloyed and alloyed steels typical in production workshops.

Application scope and process guidance

Certified for material group P (steel), the insert is intended for conventional steel turning applications where robust cutting edges and controlled chipbreaking are required. In practice, the WPP30G grade performs well across variable cutting speeds; appropriate feeds and depths of cut should be selected according to the workpiece material and machine rigidity to maximise life and surface quality. For users requiring specific cutting data for unique steel grades, technical consultation is available to align cutting parameters with process targets and to ensure safe, efficient machining.
