Abstract (en)
[origin: US2015259985A1] A short matrix drill bit is disclosed along with methods of manufacturing the same. The Short drill matrix bit includes a combination shank/blank bonded to a matrix. The combination shank/blank includes a blank portion and a shank portion, which are formed as a unitary component. The combination shank and blank may also include an outer layer formed along at least a portion of the combination shank/blank. In some instances, the outer layer is nickel plating, or some other suitable material, which facilitates wetting of the binder material used to form the matrix.
