Treated material
for stainless steel


The GC4220 series of milling inserts is conditioned with an enhanced coating and a substrate material. This treatment makes the insert optimized for use in medium to heavy duty milling operations, especially in high temperature and speeds when handling or machining hard work pieces. The insert's primary characteristic is its capacity to withstand plastic deformation and crater wear, which are both common challenges in high speed milling applications. This feature, along with its enhanced edge line and overall robustness, minimizes increased cutting data in operations. The GC4220 is specially designed for profiling, dry milling, and face milling operations. During these applications, the tool is capable of sustaining a high quality surface finish almost 30% better than conventional milling and machining tools.
