Recovery bell taps

(copy 1)


Generals characteristics

A recovery bell tap will catch the tubular object from the outside and is therefore recommended when an item of relatively small diameter is lost in a large diameter drill hole. The recovery bell tap must have a working range (ex.: small diameter 43mm / big diameter 74mm) which covers the O.D. of the rod (ex. : 60mm). Also, the O.D. of the bell tap should be the largest available but should not exceed the hole diameter.

The type of thread connection chosen should be the same as that of the fishing rod string. A choice: right hand threading or left hand threading?

Right hand threaded bell taps are intended to pull out the complete string from the hole. If the string is stuck a left hand bell tap is used for unscrewing the free part of the string.
