This full mechanical drilling jar offers mechanical jarring in both directions. The load scope of the up jarring and the down jarring is so wide that it can be adjusted in maintenance station or in site according to the requirement. The special flexible extended shaft can cut down the flexural stress of the jar body efficiently, so it is the first selected drilling jar for vertical well, deep well, complicated well and directional well operations.
