It’s the simplest fishing tool available for engaging a fish internally to catch drill pipes or drill collars.
TO ENGAGE THE FISH
It is necessary only to run the taper tap in the hole to the top of the fish, apply less than one point of weight and rotate sufficiently to embed the tapered threads of the tap into the fish, stop rotation and pull the fish.
How to order-Specify:
1) Hole size; 2) Size I.D. of the fish to be caught; 3) Top connection
