Sandvik Coromant’s GC1125 is a general-purpose grade that improves performance in parting, grooving, turning and profiling operations across a wide geometry range, the company says. The insert is said to enable machine shops to do more with one grade, offering performance benefits to a greater number of machining operations. Designed to meet the demands of the CoroCut one- to two-edge system, the insert is suited for applications in steel and stainless steels, as well as cast iron and heat-resistant super alloys. Its capabilities stem from PVD coating with multi-TiAIN layers, which combine with fine-grained substrate to deliver a wider application area. It also has the capacity to accommodate increased cutting data. According to the company, the result is improved wear and plastic deformation resistance with higher security, allowing the option of running at higher cutting speeds or for a longer time in cut.
