Product Description

The releasing and Circulating Overshot is an external catch fishing tool designed to retrieve tubular items from the well bore. It is rugged, economical, and easy to use. DX overshots come with a wide range of available accessories. This fishing tools have proven to be the most versatile and reliable in the field.
Construction:
The basic assembly consists of a top sub, bowl, and standard guide. The internal components are used to establish a secure grip on the fish to retrieve it easily. The selection of these components is determined by the diameter of the fish to be retrieved. When the fish diameter approaches the maximum catch of the overshot, a spiral grapple is required. This must also be equipped with a spiral grapple control and type A packer. When the diameter is approximately1/2inch (or more) under the maximum catch of the overshot, a basket grapple is used. It must be assembled with either a basket grapple control or a mill control packer.
Assembly and Operation:
Spiral Catch Equipment-Place the type A packer (with inside lip pointed up) in overshot bowl between upper thread and helix. (note: the lower end of overshot bowl has a longitudinal slot cut into helix.) Assemble top sub to overshot bowl. Thread spiral grapple into left-hand helix in overshot bowl. Stop threading when the grapple has fully entered the helix and the grapple tang has aligned with the keyway in the bowl. Slid the grapple control, tang end first, into overshot bowl until the grapple control tang slides beside tang on grapple. Grapple tang also slides into slot in grapple control. Now assemble the guide to overshot bowl.
