The Sandvik CoroDrill® 861 is specifically engineered to provide stability and efficiency in any drilling operations. These tips are capable of drilling deep holes up to 30x drill diameter without dealing with any breakage. These drilling tips are designed with Advanced Chip Management (ACM) that provides secured chip control and repeatability. This in turn, reduces thrust forces to protect the cutting edge from chipping and flaking. It also has an internal coolant hole that deliver cooling agents to the tips for thermal stability. Furthermore, the CoroDrill® 861, has a double offset margin patented geometry that exhibits good stability during drilling operations.
