ARRANGEMENT FOR CONTROLLING HYDRAULIC FLOW IN A DIAMOND DRILL BIT

摘要

A drill bit is provided which includes cutting elements cooperatively arranged with apertures in the bit to define flow paths for hydraulic flow proximate each cutting element. Cutting elements are preferably arranged in cutting pads which generally surround the apertures, such that hydraulic flow is forced to flow across the entire surface of the cutting pad. The dimensions of the cutting pad may be varied so as to control the hydraulic flow.
