Standard Taper Taps are not threaded for Guides. Threads will be provided on special orders at extra cost for attachment of a Guide or Skirt and Guide (or Oversize Guides).
The Taper Tap cannot be released. In some cases, you might back one out of a fish by applying left-hand torque, but extreme caution should be used when applying left-hand torque to avoid backing the string off elsewhere.
The Taper Tap is very easy to run. Run it in the hole to the top of the fish. When you think you have it in the top of the fish, rotate to the right with a neutral weight until it torques up whatever amount you need. It is a good idea to let the torque out and make it up again several times before pulling or jarring on the fish. If you pull or jar any length of time, it is a good idea to torque the Taper Tap periodically while doing this to keep it tight in the fish.
The Taper Tap will pull or jar out of the fish fairly easily because of the taper and shallow threads it cuts.
Some thought should be used before running a Taper Tap. If you have a piece of thin pipe or split pipe looking up, you would not run a Taper Tap, because it would only split the fish further as you screwed the Taper down in the fish. The Taper Tap works well on drill collars, in the top of the tubing collar, or upset and in a drill pipe tool joint. Like all other fishing tools, there is a place for the Taper Tap. This should be well thought out before running it or any other tool in the hole.
The Pip Tap is the same as the Taper Tap, except it is very short and used mostly to screw into the box of a tool joint.
