Sandvik Coromant introduces CoroBore 820, a new addition to its boring tool program. CoroBore 820 is a solution for high-productive boring, especially in roughing operations. The boring range on this tool is 35 mm to 260 mm, and three cutting edges are said to allow a higher penetration rate with maintained tool life. A comprehensive program of tool bodies, slides, shims and cutting inserts allow the CoroBore 820 to be configured to suit a wide range of possible applications. Sandvik Coromant
