Abstract
A cutting device for downhole operations includes a first cutting structure, and a second cutting structure, wherein at least the second cutting structure is selectively presentable for operation. A method of performing a downhole cutting operation comprises running into a well bore a cutting device including a plurality of cutting structures, performing a first cutting operation with a first cutting structure of the cutting device, moving the first cutting structure to selectively present a second cutting structure of the cutting device, and performing a second cutting operation with at least the second cutting structure. The method may further include aligning movable cutting structures of the cutting device to allow the second cutting structure to be selectively presented.
