Multipurpose tool

A multipurpose tool is disclosed which has as one of its purposes anchoring coiled tubing during certain downhole operations such as milling. In the anchor format the tool is run in in the retracted position and then expanded to get a grip on the casing or tubing in the wellbore prior to actuation of a downhole tool such as a mill, which is generally driven by a downhole motor. A flushing mechanism keeps the anchoring assembly free of debris so that it functions properly. The anchoring assembly employs a linkage of two or more links depending on the size of the tubing against which the coil tubing is to be anchored and the amount of anchoring force required. The same tool through a switchout of linkage components can serve a multitude of other functions on separate runs in the well or on the same run with one tool body. The tool can serve as a sleeve shifting tool, a centralizer, or a tubing end locator. The tool can expand to a ratio of greater than 1.2:1 to about 2 to 3:1 and then retract to its original run-in diameter.
