Product Introduction
Drag bit is a commonly used tool in workover operations. It is used to drill cement plug, punch sand bridge, salt bridge, scrape dirt and hard wax from casing wall and crystallize some minerals. It can also scrape the borehole to make the borehole wall clean and tidy. It can be used in liner drilling, sidetracking drilling (which can destroy the keyway formed during sidetracking) or drilling and grinding the perforation shell cushion. Under the action of drilling pressure, the bottom is fed into the drilled material such as cement, and then rotated to make the Fed part cut in the circumferential direction, gradually drilling the drilled material. Side will be grinded and milled by the drill, cylindrical space, better repair the drilled hole.
