English term or phrase: bi-center bit
bi-center bit: (n.) An integral bit and eccentric reamer used to simultaneously drill and underream the hole.


"Various bi-center bits have been used for years in various oil and gas well drilling operations. A bi-center bit is designed to drill and under-ream at the same time. It is commonly used to pass through a smaller diameter hole and then drill a larger diameter hole in one operation. It has been used in several applications, such as for example deepening or re-entry of existing wells, drilling areas where gage problems occur, increasing an annulus for cementing, prevention of drill pipe sticking, and enlarging the diameter of the borehole through the production zone".

agree  Fouad Hassaan: It is "لقمة المثقاب" so this is the correct translation for this term as it is "drilling bit" not "driller" itself
