The Ohio River at Cairo is 281,500 cu ft/s (7,960 m 3 /s); [1] and the Mississippi River at Thebes, Illinois, which is upstream of the confluence, is 208,200 cu ft/s (5,897 m 3 /s). [66] The Ohio River flow is greater than that of the Mississippi River, so hydrologically the Ohio River is the main stream of the river system.

Important for the good surface quality is the asymmetrical design of the deep hole drilling tools. The "classical" tools for single-lip deep hole drilling, BTA deep hole drilling and ejector deep hole drilling are, with a few exceptions, designed asymmetrically and have a secondary cutting edge (circular grinding chamfer) and guide pads.
