462 with -XM geometry and the CoroDrill
862 with -GM geometry support industries requiring small part manu- facturing.
“Drilling specialists gener- ally use the term micro drilling when describing holes smaller than 3 mm in diameter,” said a company spokes- person. “This can refer to holes often encountered in the electronics indus- try, where workpieces are just a few hundredths of a millimeter thick, but more common applications include the aerospace industry, mold and die making and medical equipment manu- facturing.”
CoroDrill 462 and 862 drills have been specially adapted to overcome the challenges of micro drilling. For instance, much like macroscale ap- plications, it is critical to have quality coolant to effectively evacuate chips when performing deep-hole drilling with micro tools. The CoroDrill 462 and 862 can drill hole depths of up to 9xD when using external coolant, and a through-coolant option is available for drilling diameters of 1 mm and above and hole depths of up to 16xD.
CoroDrill 462 offers high perfor- mance holemaking up to 3 mm. Suited for drilling blind and through holes, the drill is capable of machining a variety of ISO materials, including ISO P, M, K, N, S, O and H. It provides a drill depth of 6xD.
CoroDrill 862 is designed for making holes from 1 mm to 3 mm in diameter in all materials, when used with internal coolant. In addition to conventional drilling, the CoroDrill 862 supports a variety of other drilling activities, including cross holes, stack drilling and drilling of convex and concave surfaces.
CoroDrill 462 and 862 are available as both off-the-shelf and customiz- able solid carbide tools. As part of the range, Sandvik Coromant has made it
possible to configure the tools based on diameters, usable length, step-di- ameter length and shank diameter, for
manufacturers who require a bespoke approach to micro drilling.
