Downhole Fin Cutters Section:

Downhole fin cutters aid in the wireline retrieval of MWD tools when stuck pipe situations occur or MWD downhole tool failures occur and the MWD needs to pulled out of the pipe without tripping.  Downhole fin cutters are installed in the drill string at the top monel and are sized to match the connection of that drill collar.  With fin cutters installed it will trim the centralizer blades on the MWD down to 2.2” to successfully retrieve the MWD tool through the drill pipe. SMS stocks all standard connection fin cutters.  We also make custom sizes.
