Product Description

Product Description

KXJ type bumper sub is a mechanical jarring tool. It allows operators to bump up or down repeatedly until the fishing objectives are met or when the stuck drill stem is released. In event where stuck drill stem cannot be released by lifting and jarring,  the bumper sub can be rotated to engage and disengage releasable fishing tools to release the fish. In milling and cutting operations, the bumper sub is used to provide feeding force to the mechanical internal cutter, ensuring a reliable and even cut. When the bumper sub is used with a reversing unit, it helps to compensate the rising stroke for threads after reversing.
