Milling tools

Milling is one of the most varied production processes in metalworking. The process creates precise, complex components that are used in many areas. JINOO provides suitable milling tools for machining different materials depending on the application. The range extends from all-rounders to specialist tools, from conventional roughing cutters to modern HPC/HSC strategies such as dynamic trochoidal milling (GTC) or iMachining (SolidCAM). Different cutting materials are also used for the milling cutters.
