摘要: A drill bit and a method for deep-hole drilling in which the has mechanical cutting means located on its lower face solid surface upon rotation of plurality cavitating liquid jet nozzles spaced around to assist action, being so as discharge downwardly directed concentric jets that cavitate fracture be drilled series non-overlapping slots is rotated.
