  • Patent number: 5176208
    Abstract: A device for providing fluid cross over in a milling operation is set forth. It is particularly used by connection to a pipe string which supports the milling device for cutting junk from a well. It features an elongate hollow tool body having a central portion which defines a trash receiving chamber. There is a pipe inserted into this chamber from below for introducing return fluid after cutting which is laden with metal shavings, chips, and trash. In this chamber, fluid flows upwardly through the pipe, and trash collects in the chamber by surrounding the pipe falling to the bottom of the chamber by weight. The chamber is limited at the top end by transverse wall which has a number of perforations having an aggregate cross sectional area to prevent fluid flow restriction.
