Sandvik Coromant’s GC3225 grade is for the cast iron turning application area that is designed to provide secure and trouble-free machining, even in the most difficult conditions.

GC3210 grade with high flank wear resistance is suitable for turning in all cast iron materials, in good to average machining conditions. It enhances reliability and productivity in intermittent cuts, high cutting speeds, wet or dry machining, machined surface or light cast skin, the company says.

To provide the edge-line security and wear resistance necessary to optimize performance, the two grades feature a CVD coating combined with a fine-grained hard substrate. Additionally, their design uses optimized micro-geometries to facilitate light cutting action, hence reducing cutting forces and improving tool life, according to the company.

By using the insert GC3225 in machining of nodular cast iron, it was possible to increase tool life by 70 percent compared with a competitor grade, the company says. GC3210 has been tested in the machining of differential case covers with some outstanding results. After changing to GC3210 instead of a competitor grade, it was possible to increase tool life by 38 percent.
