Abstract

New drill bit with hard metal insert for drilling brick, tile and marble, characterized by being constituted by a helical drill, in whose front end, without a tip, the sections of it corresponding to two opposing points of revolution have been deleted, to admit the coupling, by welding of copper, silver, etc., of a piece that supplying the suppressed sections ends in a point; this being the hard metal insert, properly speaking, which is provided with appropriate cutting angles at all its edges.
