For smaller workpieces, vertical boring mills function almost exactly like a vertical lathe or turning center. The workpiece mounts to a chuck and rotates rapidly, while the cutting tool is stationary. The cutter is lowered into the rotating workpiece, using the motion of the part to bore out the hole.

Second, the horizontal axis design was more efficient and worked better. In general, these mills had four blades mounted on a central post. They had a cog and ring gear that translated the horizontal motion of the central shaft into vertical motion for the grindstone or wheel which would then be used for pumping water or grinding grain.
