Abstract
The present invention relates to a diverter tool used in a pipe string used to lower a liner and a cutting apparatus on the end thereof into a partially cased wellbore. The diverter tool has a diverter body that defines a longitudinal flow passage and has the diverter ports defined therethrough to communicate a drilling fluid displaced through the pipe string into the liner into an annular space around the diverter tool. The diverter tool has a closure member so that when the wellbore is drilled to its desired depth, the diverter ports through which drilling fluid is diverted may be closed and the liner may be cemented in the wellbore.
