CNMG160616-RP7 WPP20G – indexable turning insert, Tiger·tec Gold coating for steel | Walter Tools

A CNMG160616-RP7 WPP20G indexable turning insert designed for steel turning, offering a rhombic 80° geometry with a 1.6 mm nose radius and RP7 chipbreaker for stable machining.

• Tiger·tec Gold coated carbide grade WPP20G
• Designed for ISO P steels
• Rhombic 80° shape, 1.6 mm nose radius
• RP7 chipbreaker for stable chip control

Proven wear resistance for longer tool life

The Tiger·tec Gold coating combined with the WPP20G grade provides enhanced edge stability and wear resistance under the thermal and mechanical loads typical of steel machining. This coating technology reduces flank and crater wear, which translates into consistent surface finish and fewer insert changes during production. Explaining briefly: a coated carbide insert features a hard, wear-resistant layer bonded to a carbide substrate, which improves lifetime without sacrificing toughness.

Stable chip formation and reliable process security

With the RP7 chipbreaker and a rhombic 80° form, the insert controls chip segmentation and evacuation in a wide range of cutting conditions. The RP7 geometry is engineered to produce predictable chip shapes when cutting steels (ISO P), reducing the risk of entangling chips and enabling safer, more efficient cycles. This results in improved machine uptime and a smoother work sequence on turning centres and lathes.

Geometry engineered for accuracy and edge integrity

The negative clearance of 0° and the 1.6 mm corner radius deliver a balance between robustness and dimensional control. A negative rake/clearance angle supports stronger cutting edges for interrupted cuts or heavier depths of cut, while the 1.6 mm nose radius helps achieve repeatable part tolerances and acceptable surface quality. For users less familiar with the terms: a corner radius influences both strength of the edge and the achievable surface finish — larger radii increase strength but may slightly affect detail in small-radius profiles.

Economic performance in steel applications

The grade is specified for the ISO P material group, meaning it is optimised for unalloyed and alloyed steels where heat and continuous chip formation are typical. The combination of a coated carbide grade and a dedicated chipbreaker offers a cost-effective solution by extending edge life and reducing downtime. For production environments focused on repeatability and throughput, this insert supports predictable wear behaviour and stable cycle times.
