Sandvik Coromant introduces the CoroDrill 861, a brand new range of solid carbide drills for deep hole drilling applications. Featuring Advanced Chip Management (ACM) flute geometry, the new drills are able to generate small, manageable chips. This, combined with specially designed point geometry to reduce thrust forces and patented double-offset margin geometry, helps provide the high stability necessary for drilling deep holes in the most expedient and efficient manner.
