Sandvik Coromant launched two new micro-drill families designed for precision machining; CoroDrill 462 with -XM geometry and the CoroDrill 862 with -GM geometry.
The CoroDrill 462 offers performance hole making up to 3.00 millimetres. 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. With a drill depth of 6xD, the CoroDrill 462 offers manufacturers a versatile drilling solution.
The CoroDrill 862 is used for making holes from 1.00 mm to 3.00 mm in diameter in all materials, when used with internal coolant. It also supports a variety of other drilling activities, including cross holes, stack drilling and drilling of convex and concave surfaces.
The CoroDrill 462 and 862 are available as both off-the-shelf and customizable solid carbide tools. As part of the range, the tools can be configured based on diameters, usable length, step-diameter length and shank diameter, for manufacturers who require a bespoke approach to micro drilling.
Customers also have the option of purchasing the CoroDrill 862 with a polycrystalline diamond (PCD) vein cutting edge.
