Patent abstract
A process and apparatus for producing screw threads in hard material workpieces with a series of taps. The present invention employs a threaded bore formed in a bracket assembly to align and position multiple taps on a rotary machine. The taps are used in sequence to cut threads progressively deeper into a substrate. The present invention provides a method of aligning and orienting each progressive tap to begin its cut at the same initial starting point.
