Zusammenfassung:	A downhole tool includes a section mill, a bridge plug, and a connector releasably coupling the section mill to the bridge plug. A guide is coupled to the connector and maintains the section mill centered within a wellbore during sue of the section mill. A method for setting a bridge plug and cutting casing includes deploying a tool string downhole in a wellbore, with the tool string including a casing cutting tool releasably coupled to a bridge plug. The bridge plug is set within the wellbore and the casing cutting tool is released from the bridge plug. In the same trip during which the bride plug is set, the casing cutting tool is expanded and used to remove an axial section of casing while maintaining the casing cutting tool centered within the casing.
