BLAST FURNACE TAP HOLE DRILL BIT:A drilling bit for blast furnace tap holes and the like which facilitates rapid drilling of clay within the tap hole and which can be readily and easily machined to accommodate tap holes of different diameters. The bit is characterized in having inclined cutting edges which converge into a point and are separated by flutes into which compressed air is forced to rapidly dislodge the drilled clay from between the cutting edges. By virtue of the convergence of the cutting edges into a point, the bit becomes self-centering during the drilling operation.e type, steel cross bit, carbide cross bit, button bit and etc.
