Product Description

      Drag bit is a common tool which used to rework operation, for drillig cement plug and sinker drilling sand bridge, salt bridge, scraping off the dirt Ir casing wall and hard wax and some mineral crystallization. Still can scraping well hole , making the wall brightand clean, it may used to drilling ahead in bushing and side track(Can destroy the heyway is formed when side track) or drilling andrubbing the mat of perforating shell, etc.

     Under drilling and pressure effect, drilled goods as thecement is sucked at the bottom, through the rotation, the part or sucked iscutting in the direction of circumference, it will be dilling down gradually. Side lobe will be milled by drilling goods, forming cylindespace so that better dressing the well bore by drilling.
