Exchangeable-head – CoroMill®316 in HRSA machining
CoroMill 316 is a complement to our
existing solid carbide programme. Insert
geometry is based on CoroMill Plura tools.
• Roughing, semi finishing and finishing
applications in general machining.
• Cost effective solution compared to
CoroMill Plura for larger tool diameters
• Several different geometries and shanks
• Suitable for operations that demand long reach, for example
deep pockets
• High accuracy in finishing operations with long overhangs
