Detailed
The surface bumper jar type DX is an effective tool for resolving the stuck problem by producing downward jarring impact to the stuck portion. It is used to joint at the drilling platform, so the tool has the advantages of powerful jarring force, reliable tonnage-adjusting and convenient utilization. It is especially effective for freeing key-seat and tight-hole tool.
