Abstract
An earth boring drill bit having a relatively large tool passage port offset to one side of the bit centerline. The port is offset to permit substantially full bottom hole coverage of the cutting structure. The port permits various logging and sampling tools to pass through the bit to allow sampling and testing to be performed without tripping out the drill string.
